The European Food Safety Authority (EFSA) has published the last 30 th of july a report on the levels of non dioxin-like polychlorinated biphenyls (PCBs) or organic chemical substances in food and animal feed. This report indicates that the highest contamination levels were found by decreasing order in several fish and fish products, in animal products  such as raw milk, dairy products, eggs and egg products and finally in fruits and vegetables.  In animal feed, the highest levels of contaminations were found in feed containing fish derived products like fish oil. The PCBs having several effect on human health, EFSA recommends to ensure a monitoring of the presence of PCBs in the food chain.

According to a study during which analytical controls were performed on probiotic-containing food supplements, produced and distributed on the Italian market during 2005-2006, the bacteria were often not recovered in the labeled quantity, and even not recovered at all in some cases.

The survey included 41 samples from processing plants and 31 samples of the same brand from retailers collected at timed intervals (3, 8 and 13 months).

For example, the bacteria whose presence was the most often claimed (ie by 25 samples), Bifidobacterium bifidum, was only detected sporadically and always as dead cells. However, we have to remember that the definition of “probiotics” includes, among other criteria, the obligation to ensure the viability of the bacteria in the product at the time of consumption.

These results highlight a lack of analyses on these products along the production & distribution chains. It would be interesting to conduct a similar study in France.
