food recalls...some tools

let's have a look on food recalls...

The EU has one of the highest food safety standards in the world – largely thanks to the solid set of EU legislation in place, which ensures that food is safe for consumers. A key tool to ensure the cross-border follow of information to swiftly react when risks to public health are detected in the food chain is RASFF – the Rapid Alert System for Food and Feed.

Despite ...RASSF, the system does not work...
There is NO proper mechanism in place TO PREDICT emerging hazards, e.g. heavy metals in food.

I copy here the conclusions of this paper of ours...


Data from a considerable number of open field, greenhouse, and laboratory experiments, assessing the correlation between heavy metal content in soil or water and the respective metal content in food tubers, suggest that irrigation of these plants with contaminated water or cultivation of them in contaminated soils may cause build-up of risk elements in the food chain. In most cases, carrots, potatoes, and onions grown in soils with high levels of heavy metals, had significantly higher levels of these elements as opposed to respective tubers grown in control soils.
Also, it has been shown that in many cases, heavy metals induce oxidative stress to tubers, activating, respectively, plants’ enzymes with antioxidant activity. Depending on the type of heavy metal and its dose applied, the physiology of plants can be adversely affected with detrimental effects on their safety and quality. Nevertheless, in some cases, even a high bioaccumulation of heavy metals in plants does not necessarily affect their physiology.
Some implications on the dietary intake of these heavy metals and the legal gaps in the existing food legislation have been discussed suggesting that legal action is needed in order to protect consumers from heavy metal intakes related to potential health risks.
