EFSA: Salmonella main cause of outbreaks

The European Food Safety Authority (EFSA) and the European Centre for Disease Prevention and Control (ECDC) have published their Community Summary Report on Food-borne Outbreaks in the EU in 2007.

This reports shows that Salmonella remained the most common cause of food-borne outbreaks in the EU, followed by food-borne viruses and Campylobacter.

A total of 5,609 outbreaks were reported in 2007, which affected almost 40,000 people and caused 19 deaths.
The report is based on a new robust reporting system distinguishing between possible and verified outbreaks.

While the data vary considerably between Member States, a high number of reported outbreaks do not necessarily indicate a particular food safety concern but may rather be indicative that an effective national monitoring system is in place.

The report showed that Salmonella continued to be the most frequent cause of food-borne outbreaks accounting for 4 out of every 10 reported outbreaks. Of the 2,201 Salmonella outbreaks reported, 590 could be verified by laboratory detection or by analytical epidemiological evidence. The remainders were also likely to be food-borne outbreaks, but no conclusive evidence was available. These outbreaks affected 8,922 people and caused 10 deaths.

As in the previous year, viruses were the second most frequent cause of food-borne outbreaks. Altogether, food-borne viruses accounted for 668 reported outbreaks (of which 111 were verified) affecting over 3,700 people but causing no deaths.

Campylobacter followed in the list of most common causes with 461 outbreaks, of which 29 (excluding a large waterborne outbreak) were verified, affecting 244 people. Broiler meat and other meats remained the most common food source of these outbreaks.

Bacterial toxins, such as those produced by Bacillus, Clostridium or Staphylococcus bacteria were the reported cause of 458 outbreaks in the EU and 4 deaths. Member States also reported outbreaks caused by other bacteria, such as E. coli, Yersinia and Listeria, as well as parasites. 17 waterborne outbreaks were also reported, affecting 10,912 people altogether.

In 2007, a total of 5,609 food-borne outbreaks were reported by EU Member States, a slight decrease from 2006. Of the total number of outbreaks, 36% (over 2000) were verified by laboratory detection of the pathogen in food or by epidemiological evidence showing a link between human infection and the food source. The specific cause of 5 of the 19 deaths caused by food-borne outbreaks could not be identified.
