How to work towards a resilient and toxin free food system? Will emerging technologies, to manage and analyse data, be the solution to predict potential risks? These were the questions up for discussion during the 14th edition of the World Mycotoxin Forum.
The 14th edition of the World Mycotoxin Forum was held in Antwerp, Belgium from 9-11 October 2023. The conference brought together 420 participants, who joined a 3 day programme, that was packed with presentations, workshops and network opportunities. This all took place at a unique conference centre located in the Antwerp Zoo.
As with every edition of the World Mycotoxin Forum, the conference was co-hosted by local chairs. For this year’s edition the local conference chairs were Prof. Sarah De Saeger and Prof. Marthe De Boevre from Ghent University.
The topic of discussion was the current challenges impacting the food system and how to ensure the safety and security of the feed and food systems, zooming in on mycotoxin management strategies.
Food system resilience is the capacity of a food system to provide sufficient, appropriate and accessible food to all, in the face of various and even unforeseen disturbances.
Prof. Chris Elliott from Queen’s University Belfast
According to Prof. Chris Elliott from Queen’s University Belfast, UK, there are big things happening at the moment that will bring massive changes for our food system. The 4 drivers of this change are climate change, war, geopolitics and deglobalisation. To cope with these challenges we should move towards a resilience food system, explains Elliott. “Food system resilience is the capacity of a food system to provide sufficient, appropriate and accessible food to all, in the face of various and even unforeseen disturbances.”
Toxin-free food is an Illusion
Prof. Rudolf Krska from the University of Natural Resources and Life Sciences, Vienna, Austria
Food security is one thing, but what about the safety of food? The majority of consumers assume that our food is safe, after all the mandatory quality standards of food are high, but is our food really toxin-free?
Prof. Rudolf Krska from the University of Natural Resources and Life Sciences, Vienna, Austria, has a clear answer to that: “Toxin-free food is an Illusion”. The professor acknowledged that our food is safer than ever before, however a study shows that in Europe people are still exposed to harmful chemical substances and toxins. Even within the legal limits, low levels of exposure could be a risk for human health. Aflatoxins are among these high risk food contaminants, due to their potential role in the development of liver cancer. On the other side it is important to keep in mind that “humans are detoxification machines” that can overcome the harmful effects of these substances, emphasises Krska. He adds: And a healthy and balanced diet is the best way to avoid exposure to excessive doses of harmful substances.
Not only the location of the World Mycotoxin Forum was unique, with a whale skeleton hanging from the roof of the conference room, as well as the weather. Warm and sunny, not what you would expect early October in Belgium. And although it was nice to catch some sunshine during the break, it made the impact of climate change real.
The impact of climate change is clearly one of the major concerns among the mycotoxin community. Krska addressed that climate change is increasing the food safety risk, due to Aflatoxins and other mycotoxins: “Climate change will have an effect on the geographic appearance of mycotoxins and we’re also expecting major variations in emerging and masked mycotoxins. There is still a lack of data on these mycotoxins and therefore little known about the effects.” Regulatory programmes and standards for these emerging toxins are needed, according to the professor, since exposure could be a potential health risk for consumers.
Scientists often lack awareness of proper data collection, curation and sharing.
Chiara Dall’Asta from the University of Parma, Italy
The availability and sharing of data was a returning topic of discussion during the conference. Because not only is there a lack of data about emerging and masked mycotoxins, it appears that there is still little or no data on the link between climate change and mycotoxin occurrence. To be able to make well-founded predictions about mycotoxin occurrence, it is necessary to share more data in the research and business community.
The audience was asked to answer a poll question about the sharing of data:
In her presentation Chiara Dall’Asta from the University of Parma, Italy, not only addresses the need for data sharing, but also emphasises the importance of data quality. “Scientists often lack awareness of proper data collection, curation and sharing.” Therewith, Dall’Asta highlighted that analysts need to be aware of the impact that their data will have on risk assessment. Since overestimation of public health risks can lead to mis-communication to consumers what could lead to lack of trust in the food system. Proper training for the next generation of analysts and risk assessors is the key, according to Dall’Asta.
Another key element in data analysis in the future will be the role of rapidly emerging technologies like AI and machine learning. Both have potential in predicting mycotoxins in food and feed and will facilitate a more data-driven mycotoxin management. During the 3-day event a number of presentations touched on this topic, however it is likely that these developments will receive increasing intention in the near future.
It is clear that the current situation in the world, related to climate change and geopolitical situations have a big impact on our food system. On top of that it is of the upmost importance to ensure food safety. Mycotoxins are still a health threat to humans and animals and good quality and open access data management seems promising in identifying and reducing this risk.
