Assessing microbiological risks in food

The contamination of food by microbial agents is a worldwide public health concern. Most countries have documented significant increases in the incidence of diseases caused by microorganisms in food over the past few decades. Microbial hazards in food include bacteria such as Salmonella, viruses such as Norovirus, parasites such as trematodes as well as prions. Diarrhoeal diseases are the most common illnesses resulting from the consumption of contaminated food, causing 550 million people to fall ill and 230 000 deaths every year. In addition, diarrhoeal diseases may cause malnutrition and stunting, adding to the amount of Disability-Adjusted Life Years (DALYs) resulting from the consumption of contaminated food.

WHO develops scientific risk assessments, guidelines for risk management and risk communication messages for all stakeholders, including the end users, to assist Member States to improve their capacity to prevent and control foodborne diseases.

JEMRA expert roster

JEMRA is tasked with the evaluation of different aspects of microbiological hazards in the food supply. This roster consists of scientific experts who have submitted applications in response to public calls for experts on Risk Assessment of Microbiological Hazards related to food safety. The applications were reviewed by the FAO and WHO Secretariats and by an external referee, and selections made on the basis of the criteria outlined in the call for experts. Scientists of the roster will be considered for future meetings of JEMRA according to expertise required for the respective meetings.
