    Background Human dietary exposure to chemicals can result in a wide range of adverse health effects. Some substances might cause non-communicable diseases, including cancer and coronary heart diseases, and could be nephrotoxic. Food is the main human exposure route for many chemicals. We aimed to assess human dietary exposure to a wide range of food chemicals. Methods We did a total diet study in Benin, Cameroon, Mali, and Nigeria. We assessed 4020 representative samples of foods, prepared as consumed, which covered more than 90% of the diet of 7291 households from eight study centres. By combining representative dietary surveys of countries with findings for concentrations of 872 chemicals in foods, we characterised human dietary exposure. Findings Exposure to lead could result in increases in adult blood pressure up to 2·0 mm Hg, whereas children might lose 8·8–13·3 IQ points (95th percentile in Kano, Nigeria). Morbidity factors caused by coexposure to aflatoxin B1 and hepatitis B virus, and sterigmatocystin and fumonisins, suggest several thousands of additional liver cancer cases per year, and a substantial contribution to the burden of chronic malnutrition in childhood. Exposure to 13 polycyclic aromatic hydrocarbons from consumption of smoked fish and edible oils exceeded levels associated with possible carcinogenicity and genotoxicity health concerns in all study centres. Exposure to aluminium, ochratoxin A, and citrinin indicated a public health concern about nephropathies. From 470 pesticides tested across the four countries, only high concentrations of chlorpyrifos in smoked fish (unauthorised practice identified in Mali) could pose a human health risk. Interpretation Risks characterised by this total diet study underscore specific priorities in terms of food safety management in sub-Saharan Africa. Similar investigations specifically targeting children are crucially needed.

    Thailand's Food Safety Project on Restaurants and Street Vendors: the

    In Thailand, restaurants and street vendors can easily be found along the streets in not only the tourist areas but also in any community in Bangkok and all other provinces. One reason is that today more and more Thais do not cook at home anymore. Smaller families of only two or three and for some, fast-pace city life with less time to spare make cooking a task to avoid. By four or five in the evening, street vendors are ready at their stalls with varieties of already cooked foods to be chosen b y customers on their way home. Thousands of tourists to Thailand each year also find this way of life intriguing. The food looks great, the taste is superb, and the price is cheap. The only question left is safety.
