Are we geared to handle aflatoxin problem meaningfully?
By Emeritus Professor
The media is full of information about the dangers of aflatoxins, increasing fear in the minds of public. Exposure to extremely small doses of aflatoxins of the order of micrograms per kilogram for long periods leads to liver cancer in humans and animals. Aflatoxins can also cause deaths within a few days if people are exposed to extremely high doses of it. In the world, there has been only one such recorded incident due to toxicity; 105 people died after consuming aflatoxin contaminated maize, during a famine in a neighbouring country. The toxic dose was around 20 mg per kilogram. That was in 1975.
In addressing a sensitive issue such as toxicity of human foods, the background scientific information needs to be understood in its correct perspectives to discuss and explore benefits of science to mankind. Aflatoxins are present in most foods in minute quantities. Unfortunately, none of the common food processing and preparation methods including heat processing or cooking could remove the aflatoxins significantly. In case of edible oils, aflatoxins could be removed industrially, only by chemical (alkali) refining. The treatment removes 98% aflatoxins in oils, bringing down aflatoxin concentrations in edible oils to levels safe for consumption. Other methods of ‘refining’ cannot remove aflatoxins. There is a patented process in Sri Lanka to remove aflatoxins in coconut oil using solar radiation. It needs to be scaled up for industrial use.
Humans do not live in an ideal world. We survive in a world of toxins, whether it is aflatoxin, other mycotoxins (mould toxins), heavy metals, like cadmium, mercury, lead or arsenic, or histamine in tuna fish, which causes allergic reactions, familiar to some of us. The list is much longer. We have learned to consume manioc containing cyanide by boiling in open pots to remove toxicity. Manioc is the staple diet in some of the African countries, but they live with it. Sri Lankans have learned to use goraka as a means of checking histamine producing bacteria in tuna fish. Panic should be avoided when it comes to understanding and handling the problems associated with foods.
Science has developed mechanisms to understand the amount of toxins that could be metabolized by the human body safely. Based on this information, risk level for each of the toxic entities in foods is worked out. The risk level is finally established at a concentration a few 1000 times less than concentrations experimentally established to be safe to humans. This simply means world possess regulatory systems, and dependable accredited testing systems, to make food consumption safe, avoiding naturally occurring undesirable constituents. It applies to aflatoxins as well. The volume of a food consumed by a human is also considered in deciding acceptable or tolerable levels, expressed based on per kilogram body weight of the consumer. Weight of the human body and the concentrations of deleterious entities that could be consumed without harmful effects are combined in establishing no-risk levels. Human health is primary in the efforts of sound science to make us live longer. That is food safety.
Ever increasing human populations against available lands and other resources to produce foods require new mechanisms to ensure food security. This is where strict application of ‘good practices’ in agriculture, food processing, and hygiene contributes to the well-being of humans through safe foods. There is the need for striking the best balance between protection of human health and possible application of good practices in food production to enable humans leade healthy lives without becoming a burden to the public health systems.
The food regulations meant to trike this balance continue to change with increasing scientific knowledge of human health as well as fast developing food processing technology. In the developed countries, food regulations are revised frequently to strike the above balance beneficially for humans. The same cannot be said of most developing countries. Sri Lanka is no exception. However, there are ample opportunities for countries, without adequate resources, to develop their own regulations adopting scientifically designed international “Codex” food standards, without reinventing the wheel.
“Codex” stands are developed by the Codex Alimentarius Commission, which is a joint committee of the FAO and WHO.
The international system gives the opportunity for every country to improve its knowledge, taking into consideration the developments in the scientifically advanced countries, and practices of food handling. Codex knowledge helps all countries to develop food standards in line with world trade, which is also an important aspect in our export trade. Sri Lanka needs to be more tuned to get these benefits.
Taking the current global thinking and Sri Lanka’s needs into consideration, the table for aflatoxin regulatory limits was computed with the field experience of the author on food safety issues in more than 25 countries. It was made available to the health authorities in Sri Lanka a few months ago and Institutions interested in standards a week ago. It addresses the levels of acceptance or tolerance (ML = meaning maximum limit that could be tolerated in a food) for aflatoxins in common foods and feeds in Sri Lanka. The proposal also considered the test results generated in local accredited laboratories.
It focuses on the direction to be followed by Sri Lanka to address aflatoxicity problem. The responsible administrators and policy makers may use it. The scientific reasoning to keep the balance between health and food processing is summarised as notes in the table against each recommendation.
This information would be useful to the public, and those who are interested in understanding regulations in relation to presence of aflatoxins in foods in Sri Lanka. The proposed regulations would not contradict any of the globally used regulations in food trade.
Establishing standards is one thing. Applying it through testing only is the proof of the pudding. The interpretation of the generated test results is even more vital. The writer has tested more than 1,000 samples of foods including large number of coconut oil samples for aflatoxins in Sri Lanka and the US, working at the bench, and interpreting results for internationally recognised publications. The aflatoxins tend to adhere to laboratory glassware, and give a positive reaction for the next sample tested unless special cleaning techniques are used. This adherence can happen with any storage surface including container and bowser surfaces. The surfaces of bulk storage systems are never cleaned to get rid of the aflatoxins. Cleaning to remove storage tanks is practically impossible.
The interpretation of test results should be done with deep knowledge of background information. In interpreting test results for field samples, we need to be mindful that local coconut oil contains small concentrations (of the order of 5 -15 parts per billion) of aflatoxins and the imported oil (100 – 300 parts per billion, if what we hear in the press is correct). Skills of the scientist must go far beyond analyst, and the digits generated by instruments through the testing step. Interpretation of results is not a job for the layman. The testing requires demonstrated competency of analysts through continuous practice. Therefore, we need to resort to a laboratory accredited for the purpose. Gazetting a laboratory as public analyst or use of laboratories which holds accreditation for other tests, but not for aflatoxins, particularly oils, are not the best scientific approaches. Let us be mindful that we are discussing handling of human health through assessing an invisible toxin.
I sincerely believe that the decision makers take the above aspects into consideration in data interpretation responsibly, without leaving it to the newsmakers.
SUSTAINING ECONOMIC PROGRESS AND OBTAINING ‘SYSTEM CHANGE’
by Jehan Perera
A year after the protest movement took off into a mammoth public display of the popular desire for change, it appears to be no more. What appears on the streets on and off is a pale imitation of the mighty force of people rich and poor, from north and south, who occupied the main roads of downtown Colombo for more than three months. The government under President Ranil Wickremesinghe is leaving no room for the people to get on the streets again. This has been through a combination of both efficient and repressive policies that exceed those of the predecessor government.
The government has addressed the immediate causes that brought the people out on to the streets. The crippling shortages of vehicle fuel and cooking gas that caused long lines stretching for kilometers are not to be seen. There is enough to go around now as the demand for these basic commodities has dropped considerably following the tripling of their prices. There is an outward appearance of normalcy that belies the economic difficulties that the masses of people are facing. The three-wheel driver lamented that his monthly electricity bill of Rs 700 was now Rs 3200 which made keeping his refrigerator unaffordable. Government officers on fixed incomes are struggling to survive having pawned their jewellery and mortgaged their lands for survival. Those who can leave the country seem to be leaving.
The government has also shown it is prepared to use the security system to its maximum. This has won some supporters especially among the upper social classes and ethnic minorities who are always worried whether mobs of the under classes will invade their neighborhoods and subject them to looting and violence. After becoming president, President Wickremesinghe showed his resolve in bringing the protest movement to heel by sending the police to break it up and arrest the leaders. Protestors have been warned that their protests should not inconvenience the general public.
Those who do not heed the police guidelines have found themselves being tear-gassed, baton-charged and arrested. In contrast to the heyday of the protest movement a year ago, any voice of public dissent is liable to be quickly suppressed. A case in point would be that of the unfortunate hooter. As reported extensively in the media, a government minister who was laying a foundation stone for a religious shrine was hooted by a businessman who was travelling in his vehicle. The media reported that “the police acted swiftly, pursuing and apprehending the suspect. He will now be produced before the court for obstructing a religious ceremony.”
The contrast with what happened a year ago could not be more stark. The main slogans of the Aragalaya protests was to arrest the rogues who had bankrupted the country and compel them to bring back to the country their ill-gotten gains. The draft Anti-Terrorist law that has been approved by the Cabinet to replace the Prevention of Terrorism Act is, in many ways, a more repressive law that will encompass a much wider swathe of social and political life. Clause 105 in it defines a “person” who can be taken into custody under this law to mean an individual, an association, organisation or body of persons.” Readers of George Orwell’s classic novel of authoritarian government, “1984” would feel a chill if that new law is passed when they think of protesting against the government.
A key demand of the protest movement last year was the demand for “system change.” At its core this was a desperate call for a change of government that had bankrupted the country and accountability and punishment for those who had impoverished the people by their mis-governance, corruption and indifference to the people’s plight. Another terminology for “systems change” would be to say that the people called for a new “social contract.” The notion of a social contract between rulers and ruled was developed over four centuries ago in Europe by Enlightenment era thinkers such as by John Locke in England and by Jean-Jacques Rousseau in France who gave the name “The Social Contract” to his 1762 book.
The social contract theorists argued that people left the state of nature where without government life was “solitary, poor, nasty, brutish and short” (as described by their predecessor Thomas Hobbes). People entered into a social contract with those who would govern them. In terms of the social contract, the people would give up some of their rights and freedoms in exchange for protection and order by the government. In modern democracies, people elect their representatives who form the government of the day and look after the best interests of the people. But in March 2022, the people of Sri Lanka felt hat their government had not lived up to the social contract and demanded they leave office and return their ill-gotten gains.
Those who continue to come out on the streets in protest demand elections and also demand to know why the government has not made efforts to bring back the money that was stolen. What is visible at the present time is that most of the government members who were responsible leaders of the previous government continue to remain in positions of power, either frontally or behind the scenes. There continue to be allegations of corruption and abuse of power. In one appalling instance, two government ministers resigned from a watchdog committee they were appointed to. They complained that they were not getting the information they required to play their assigned roles.
Sri Lanka has yet to address the monumental failure of government that took place in the early part of 2022 that plunged the country from a middle income level to a low income level. When the people went out on to the streets to protest and call for a “systems change” they were demanding that the government should step down and go. But it did not go and instead re-arranged itself and continues to be in power. Much to the chagrin of the protest movement, the government they wanted to go has grown stronger under the leadership of President Ranil Wickremesinghe and is ignoring the demand for “system change” and those who call for local government elections which are overdue.
Speaking to students at Harvard University last week through the internet, President Wickremesinghe made it known that the government would abide by the Supreme Court’s decision with regard to the elections. A confrontation involving the three branches of government would signify a “systems breakdown” in place of the “systems change” that people fought for a year ago. The president has also taken pride in announcing that the government will soon be passing into law the best anti-corruption legislation in South Asia in parliament soon. If the president’s vision of sustainable political stability and economic recovery is not to be a re-enactment of the Orwellian dystopia of 1984, there needs to indeed be a “systems change”, a plan for the future prepared in consultation with the opposition and civil society and a new “social contract” in which elections would be the first step.
Free Education, Social Welfare and the IMF Programme
by Ahilan Kadirgamar
Sri Lanka’s seventeenth IMF agreement sealed last week may well prove to be the most devastating one of them all. The reason is that the agreement comes along with Sri Lanka having defaulted on its external debt for the first time in its history. The IMF amounts to being the arbiter of the debt restructuring process with Sri Lanka’s external creditors, which will provide considerable leverage for Sri Lanka to be held accountable to IMF conditionalities.
The fallout of the IMF package will be wide and deep, greater than the Structural Adjustment Programm e with the IMF in the late 1970s, when our cherished social welfare system came under attack. In this Kuppi column, I address some of the dangers facing our education system. Education is inextricably linked to welfare and democracy, and in the years ahead the nexus of the IMF and the current avatar of the neoliberal state are likely to impose an authoritarian regime of dispossession. The future of Free Education in our country now depends on tremendous resistance by our students and teachers along with solidarity from all quarters of the working people.
Welfare and democracy
Social welfare in Sri Lanka reaches back to the 1940s. It included food subsides, free education and free healthcare, which were all universal schemes. The IMF packages and the World Bank programmes since the neoliberal turn in the late 1970s have consistently attempted to weaken such universal social welfare programs in the interest of creating a market economy, including through the commercialisation of education and healthcare. Neoliberal ideology privileges the individual, and by the same token places the entire burden of wellbeing on the individual. As the British Prime Minister Margaret Thatcher—who, along with US President Ronald Reagan, initiated the neoliberal age on a global scale—famously said, “there is no such thing as society”.
This rejection of society is at the heart of the attack on social welfare, as the IMF and World Bank are now in the process of changing the very idea of social welfare itself into a narrow concept of targeted cash transfer programmes. This attack on the social aspect of welfare entails both granting enormous discretionary power to those in power to determine which individuals can obtain minimal support, in addition to the monetisation of such entitlements, which over time would likely be reduced or inflated away.
Historically, universal social welfare came after the policy of universal adult franchise in 1931. Furthermore, universal free education policies, as they emerged in the mid-1940s, were framed in terms of strengthening the ability of Sri Lanka’s citizens to exercise power through their democracy. In this context, today’s attack on universal social welfare is a key part of the agenda of an illegitimate and undemocratic regime in power. Moreover, the regime’s vision of the education system derives from the IMF’s technocratic assumption that the goal should be to create subservient employees for a market economy, rather than democratic-minded people who can become agents of social, economic and political change.
Austerity, dispossession, and resistance
The attack on education is not only ideological, in terms of the neoliberal emphasis on individualism. The austerity measures that are inherent to the current IMF programme are also material. They are bound to reduce the allocations for education. The Government is being forced to find avenues to create a primary budget surplus by next year. This will further lead to initiatives for the commercialisation of education; for example, the expansion of fee-levying programs in the state university system, loan schemes for education, and the initiation of private educational institutions, including private universities.
The logic of the IMF programme and the unfolding developments will dispossess people of one of their most important social welfare entitlements: education. There is already evidence of rising school dropouts, of children not being sent regularly to school, children fainting at school due to the lack of food, and children having to labour for their existence. University students are finding transport costs unaffordable and even lunch packets are becoming out of their reach. These are the consequences of a contracting economy due to the austerity measures that have been imposed. Indeed, our economy has contracted by as much as a fifth over the last few years. The critical gains of social welfare made after the Great Depression of the 1930s in our country are now in danger of being completely rolled back because of the ongoing economic depression along with the IMF programme making it worse.
The dismal prospects for our country can only be addressed by solidarity and resistance. We need to regain our sense of social belonging, which was undone through the very attack by neoliberalism on the idea of society, while taking forward the struggle for democracy. The great struggles last year that dislodged an authoritarian populist president provide hope that despite decades of neoliberal policies, working people’s capacity to envision society, solidarity, and resistance are very much alive.
We are going through the most painful period of our postcolonial history. It is a moment in which, even as our economy is collapsing, our elite are working in cahoots with the IMF and global finance capital, which have achieved a stranglehold on us by leveraging the default and the bankrupt state of our country. In the context of this existential danger, for those of us concerned about safeguarding free education and, for that matter, any meaningful system of education, this time around that struggle must begin from a broader defence of social welfare and democracy.

The Box of Delights – II
Seeing through testing times and future
Text of the keynote address by Prof Rajiva Wijesinha
at the 8th International Research Conference on Humanities and Social Sciences,
University of Sri Jayewardenepura on 16 March, 2023.
Sadly, too, the GELT materials we produced are now forgotten, though in the end they were taken up by Cambridge University Press in India and prescribed too at some Indian universities. But in this country producing materials is a way of making money and so, though three years ago the UGC asked about using our materials again, they were prevented from making use of these, and individual universities demanded autonomy and nothing went forward as swiftly as our poor youngsters needed.
Delay also affected the curriculum reform I initiated when I chaired the NIE AAB [Academic Affairs Board]. I had told the then Education Secretary Tara de Mel that we should move immediately, but for once that normally efficient lady was diffident, and said we should wait. Six months later she told me to go ahead, and we did, swiftly, but then Chandrika Kumaratunga lost a year of her Presidency through carelessness and the new President and his Minister simply did not understand the need for continuity, and the vital changes we had embarked on were forgotten.
But Mahinda Rajapaksa and Susil Premjayanth did continue with perhaps the most important initiative begun under Tara—the English medium in secondary schools in the government system. That had begun in 2001, but was sabotaged by Ranil Wickremesinghe, who became Prime Minister at the end of that year. But his Minister of Education, Karunasena Kodituwakku, a former Vice-Chancellor of this University, was more enlightened, and ignored Ranil’s instructions that he halt the programme, and it continued. He was lucky not to be tear-gassed, but, in those days, there were some restraints on unbridled authority with the forces then more supportive of alternatives.
But the teacher training programme I had started with support from Paru and Oranee, had to stop. The NIE then took that over and completely destroyed the learner friendly approach we had initiated, with its hierarchy promoting formulas, such as three Ts and then five Es and seven Ks, gloriously asserted in lengthy sentences such as ‘Also the teacher should closely observe the children learning, identifying students’ activities, disabilities, providing feedback, developing the learning capacities of the students and making implements to extend the learning and teaching outside the classroom are some other tasks expected from the teacher.’
As I commented on this in English and Education: In Search of Equity and Excellence?, ‘It might seem churlish to cavil about the two main verbs in this sentence, were this not an instructional guide to English teachers, with three language editors who have doubtless been well paid for their pains, or the lack of them.’
Training then was in the hands of the NIE, and the programme began to flounder. But, fortunately, the contract to produce books had been for two years, and Nirmali continued in charge of this, so at least a good foundation was laid, though after that the Ministry and the NIE took over and the usual tedious stuff was reintroduced. Our efforts to introduce wider knowledge, and creative thinking, were abandoned totally, unsurprising given the ignorance I had found in those entrusted with producing textbooks at the NIE (which managed once to produce a history syllabus which left out the French and the Industrial Revolutions in the whole secondary school curriculum). Let me, to prove my point, give you an extract from what the NIE managed to produce
‘Red the story …
Hello! We are going to the zoo. “Do you like to join us” asked Sylvia. “Sorry, I can’t I’m going to the library now. Anyway have a nice time” bye.
So Syliva went to the zoo with her parents. At the entrance her father bought tickets. First, they went to see the monkeys
She looked at a monkey. It made a funny face and started swinging Sylvia shouted.
“He is swinging look now it is hanging from its tail it’s marvellous”
“Monkey usually do that’
And, so it seems does the NIE, was my comment. Unfortunately, I cannot in a speech make clear the carelessness with regard to punctuation and spelling, but a printed version will show just how appalling the NIE usage of English is and the callousness of inflicting half-baked stuff on our children.
Despite all this English medium has survived, but that it could have done so much better is obvious from the continuing proliferation of private English medium schools. Interestingly, the former Permanent Secretary to the Ministry of Education, Dharmasiri Peiris, whom I met after many years, reminded me that in the early nineties he had wanted me to work at the Ministry to remedy the situation, but he had abandoned the effort when officials at the Ministry opposed this, understandably so given that I do not tolerate nonsense. And though Tara was made of sterner stuff, and did make use of my services, two changes of regime before things could be consolidated meant that our children still get short shrift as far as English Language Learning is concerned.
I have spoken thus far of English at university level and in schools. I have also worked on English for vocational training, first thirty years ago when the World University Service of Canada commissioned a basic textbook for those starting on vocational training, then more comprehensively when I chaired the Tertiary and Vocational Education Commission.
Having discovered that what were termed NVQ Levels 1 and 2, supposed to prepare youngsters for vocational training, hardly existed, I started Career Skills courses at those levels, to develop other soft skills and in particular English capacity, and these rapidly became the most popular courses in the system. After all, I had done a trawl and found that parents wanted something for their children to do in the fallow period after the Ordinary Level examination. Uniquely, Sri Lanka wastes the time of its youngsters by delaying the resumption of school, a boon to the tuition industry which embarks on recruitment and hooks youngsters for the next few years.
Needless to say, when I was sacked, the English courses were abolished, and successive Ministers of Education, who now have charge also of vocational education, bleat about the need for more English but do nothing to promote this. Least of all do they think of learning from the past, and far from reinventing the wheel, they simply talk about movement while allowing all means of transport to be dismantled, with parents and children who have been left in the lurch turning if they can to private education, tuition in particular.
As your former Vice-Chancellor perceptively put it, when I was last here, the education system is abandoned by those who have the means to pursue alternatives, and it is only the most deprived who cling to it. And whereas any country with a conscience would do its best by the deprived, decision makers in Sri Lanka do not care about them – like the Mr Lokubandara, who ranted against English in the state system and sent his son to an international school, and then when I reprimanded him told me sanctimoniously that it was his wife who had insisted on that.
Is there then no hope? I fear not, and now I can understand the despair of Mabel Layton in Paul Scott’s brilliant analysis of the failure of the British in imperialism, and her lament that “I thought there might be some changes, but there aren’t. It’s all exactly as it was when I first saw it more than forty years ago. I can’t even be angry. But someone ought to be.”’ I rather fear then that your Vice-Chancellor’s observation will prove even more apposite in the years to come. There was a brief moment three years ago, when covid first hit us, when I thought the system would bestir itself to provide alternatives, but I fear nothing of the sort happened.
But let me end now with what should have happened. Given that the onset of covid saw closure of schools and institutions, there should have been efforts to develop curricula appropriate for a time when face to face contact would not be easy. And this required, as I started by saying, thinking as learners do, and tailoring the content of curricula, as well as systems to convey it, to the abilities of learners, not teachers.
This was particularly important in the context of 2020 in which learners had limited access to teachers. But our decision makers could not think on these lines, nor understand that the key to this was simple materials, that are not just user friendly but that will allow learners to gain not only knowledge but also relevant thinking skills on their own. Provision could and should have been made for guidance, but this had to be minimal, and also provided through small group clusters, where students could learn from each other, in addition to getting guidance at a higher level as available. I recall vividly the brilliant initiative of Oranee Jansz, in insisting that all GELT students not only did a project, but that they dramatized this. This proved a wonderful motivating factor, and students in the remotest of areas worked hard together, and the synergy they developed, to use one of Oranee’s favourite words, led to rapid learning by even those who had been initially very weak.
Such a system was especially important for youngsters in rural communities, and could have been activated in 2020, at a time when communication was difficult, and where the panacea authorities developed, of online contact, was not easy, and in many instances not even possible. But as I have noted, those rural communities are of no concern to our decision makers, whose main motivation is to have their children advance through educational systems different from those the majority of our children have to undergo. They are not at all like Oranee, or one of the academics I remember most fondly from my time at this university, Prof Wickremaarachchi, who started an accountancy course in English medium only, and noted that one had failed as a teacher if one’s students did not end up better than oneself.
To continue, in the midst of a country in a desperate plight, with the positives this university could develop, I will revert to the last time I was here, in December, and highlight again the initiative I mentioned when I began, to work through the national library system to promote English through entertainment for early learners. The project which has been developed suggests at last, after two decades, an effective approach to extending opportunities and means of learning.
This can easily be taken further, at all levels – and work on this has begun – to fill gaps that the state has sedulously ignored for several decades. Costs would be minimal, if only innovators such as the personnel here responsible for the initiative were given a free hand. I can only hope that, with the support of the hierarchy here, and the other players who have combined to take this forward, from the Governor of the Northern Province to the Chairman of the National Library Services Board, that this initiative will lead to the proliferation of user friendly materials and personnel able to use them productively.
