 This species, which is sanitary security, is a very important aspect. As we know it, from the consumer's point of view, and from the economic development point of view. But often there are huge gaps in knowledge on the contaminants that affect food that's consumed domestically and exported. In all countries with limited means, we need to tackle the most important problems to be able to get out of the protection of health. We need to make sure food is safe. When it is safe, it keeps diseases away. When we keep our national food supply chain safe, it helps in promoting our trade. We have a lot of contaminants that are contaminated, not chemical contaminants. And this is causing a lot of health problems. For example, we have cancer problems. We also have children's development problems. To be able to do this study in Benin, in Cameroon, in Mali and in Nigeria, we have studied the diet of more than 70,000 menages. We have then collected more than 4,000 samples representative of food habits. A total diet study consists of the production of contaminated food, that we are going to cross with consumption data for the people concerned. All of this will give us exposure data, which will bring us to characterize the risk. We have noticed that some food was strongly contaminated by certain substances. Arachid oil and corn were relatively strongly contaminated by toxins. Some high-carb hydrocarbons were found in very important concentrations of smoked fish. This is also the case for some cooking oils. Almost half of the collected samples contained pesticides, some of them in the form of traces and others in very important containers. The results from this study will actually inform the standard development in Codex because there have always been lack of data from Africa. Now, the study has provided that necessary data and it can be built on by more other countries and generating more data. This study will help us identify national priorities in the elaboration of norms on the different products, especially the products used in the study. This study will also allow us to put in place surveillance plans of these different health risks. We may decide on working on a guidance document for the farmers, for the primary producers, things like guidelines that will help in reducing some of these contaminants in food supply. The study's evidence-based approach provides a scientific basis to meet international standards. In Benin, Cameroon, Mali and Nigeria, as well as the region as a whole. Building on the national priorities identified through the Total Diet study, donors can work with governments to target resources to improve food safety for domestic public health and trade. We need to co-work together in the aspect of even translating the issue of food safety to the level of lower education. I know that everybody has a role to play. It's a collective work. For us to ensure that the national food safety space is secured and safe. It all comes together as consumers, as authorities, as research services, as a double effort to find solutions and then to be able to know the causes of these different risks. Because when we know the cause, it would be easier to find the solution to such or such problems.
