Scientists at Europe's food safety watchdog have updated advice on the risks from Listeria
The Scientific Panel on Biological Hazards (BIOHAZ) of the European Food Safety Authority (EFSA) recommends that efforts to reduce risks to human health should focus on risk reduction practices both during the production process of ready-to-eat foods (RTE) and at home by consumers.
The Panel recommended that to better assess the risk of the foods responsible for listeriosis it was necessary to investigate listeriosis cases more thoroughly and generate and analyse data on the consumption in the EU of ready-to-eat foods in which Listeria
, a bacterium causing a food-borne disease which is on the increase, can be found.
Different approaches are taken by public authorities across the world in monitoring the levels of Listeria
. In the European Union, there are maximum safety tolerance levels for Listeria
in food products.
The panel concluded that keeping to these limits leads to very low numbers of listeriosis cases in humans as most listeriosis cases are due to the consumption of ready-to-eat foods which support growth of Listeria
and develop a high concentration of Listeria
along the food chain.
In its advice to industry, the panel identified the following as key areas for attention: food packaging and preparation practices in the food chain (such as the slicing of RTE meat products), storage temperatures, general industrial good hygiene practices and the education and training of food handlers.
The Panel also advised that consumers should continue to observe recommended storage temperatures and keep food appropriately chilled at all times, and take note of the shelf-life of food in their refrigerators. Good food hygiene and preparation principles also play an important role in the prevention of Listeria
and other food-borne infections.
Listeriosis is a rare but potentially lethal food-borne infection caused by Listeria
monocytogenes which has a high mortality rate. Elderly people and pregnant women are particularly vulnerable to listeriosis as are people suffering from immuno-compromising diseases.
The work by the BIOHAZ panel follows a request by the European Commission to EFSA to update the scientific review of literature on listeriosis related to ready-to-eat foods.
