Europe – EFSA – Foods of Non-Animal Origin: What are the Risks?

EFSA – Full Report at this link efsa

Foods of non-animal origin – such as fruit, vegetables, cereals, and spices – are an important part of our daily diet. Usually these types of food are associated with healthy eating and do not pose any health concerns. However, sometimes their consumption causes mild to severe illnesses.

Over the past 4 years, EFSA has looked closely at the risks posed by foods of non-animal origin. EFSA’s Panel on Biological Hazard, with the support of the working group on foods of non-animal origin, assessed the public health risks posed by pathogens (disease-causing bacteria, viruses and parasites) that may contaminate these foods. The Chair of the Working Group, Jim McLauchlin, guides us through the main findings of this significant piece of work.

What are the risks posed by these foods?

A wide range of hazards are associated with different foods. In our work, we have identified and ranked combinations of foods and pathogens.

The top-ranking combinations of foods and pathogens are Salmonella and leafy greens eaten raw, followed by Salmonella and bulb and stem vegetables; Salmonella and tomatoes; Salmonella and melons; and pathogenic E. coli and fresh pods, legumes or grains.

Other pathogens that can be transmitted are norovirus, Shigella, Bacillus, and Yersinia as well as the hepatitis A virus.

Which foods pose the highest risks?

Amongst raw and minimally processed foods of non-animal origin, those that pose the highest risks in the EU are leafy greens, bulb and stem vegetables, tomatoes, melons, fresh pods, legumes or grains, sprouted seeds and berries.

These foods can be consumed in a variety of ways – from raw to highly processed and are generally free from noxious substances, such as poisonous chemicals, toxins and pathogenic organisms. Occasionally though, their consumption causes serious illnesses, which can be fatal. For example the 2011 sprouted seed-associated outbreak of Shiga-toxin producing Escherichia coli in Germany caused 53 deaths and more than 2,300 hospitalisations.

 

FDA – Reportable Food Registry Annual Report Third Annual Report: September 8, 2011 – September 7, 2012

FDA

This is the third annual report that measures our success in receiving early warning on problems with food and feed. The Reportable Food Registry (RFR) has already proven itself an invaluable tool to help prevent contaminated food from reaching the public.

By providing early warning about potential public-health risks from reportable foods, the Registry increases the speed with which the FDA, its state- and local-level partners, and industry can remove hazards from the marketplace.

The RFR data also is providing valuable data to help meet requirements under the Food Safety Modernization Act. For example, we can use the data to identify hazards associated with products for which we have not previously made such an association and thus identify foods for which preventive controls may be needed. The data are also being used to help target inspections, plan work, identify and prioritize risks and develop guidance for industry. The FDA will continue working closely with the food and feed industries to enhance this important and beneficial tool.

CDC Letter – UK Shellfish Market and Viruses – Hepatitis E

CDC (full letter)

Bivalve mollusks (shellfish), such as mussels and oysters, are filter feeders; they concentrate microorganisms of human and animal origin (up to 100×) from the surrounding environment. Several recent reports have linked the incidence of human infection with hepatitis E virus (HEV) to consumption of undercooked pork, game products, and shellfish (1,2). Infectious HEV has been found in swine manure and wastewater (3); therefore, application of manure to land and subsequent runoff could contaminate coastal water, leading to contamination of shellfish and, subsequently, possible human infection. Because they are filter feeders, bivalve mollusks are biologically relevant sentinels and can indicate potential pathogens that are contaminating the environment. It is essential to ensure that this sustainable resource of coastal areas, where mussels and oysters are farmed or collected wild, is not subjected to environmental contamination that could lead to public health risks.

Risk management for bivalve mollusks, aimed at control of fecal pollution, relies heavily on the use of Escherichia coli as an indicator of fecal (sewage) contamination and is enacted under European food regulations (Regulation 854/2004, www.cefas.co.uk/media/455777/extract_reg_no_854_2004.pdf Adobe PDF file). However, although these regulations probably reduce the number of infections, especially bacterial infections, they are not viewed as adequately controlling the risk for viral infections. Specific risks are posed by the robustness of viruses in the environment and the different behavior of viruses within bivalve mollusks compared with behavior within bacterial fecal indicators.
