Abstract:
Metals such as cadmium and lead are natural occurring chemical compounds. They can be present at various levels in the environment: soil, water and atmosphere. Metals can also occur as residues in food because of their presence in the environment, resulting from human activities such as farming, industry, car exhausts or from contamination during food processing and storage. People can be exposed to these metals from the environment or by ingesting contaminated food or water. Rapid Alert System for Food and Feed is established to reduce the direct or indirect risk to human and animal health. We can analyze the trends of heavy metals (HM) hazard from the number of market notifications with maximum level (ML) exceeded, received from Member States and third countries, in 2001-2008.
Cadmium in fishery products (ML 0.05-0.3mg/kg) has a very high peak in 2003 and in 2004 a peak is observed for cadmium in fruit and vegetables (ML 0.05-1mg/kg). Zinc is most common in dietetic food and food supplements.
Too much lead and cadmium is regularly found to migrate from designer ceramics or drinking glassed, ML for lead is between 0.8mg/dm2-1.5mg/l and for cadmium is between 0.07mg/dm2-0.1mg/l depending on composition and area. Migration of lead from food contact materials had a peak in 2005 and now the number of notification is on the rise again, also migration of cadmium has a small increase in 2008. Taking into account data from 2003-2008 Italy, Estonia, Germany, England, Belgium and France have the highest number of notifications regarding HM hazard.
In Romania in 2005, from the number of samples analyzed for determination of HM in food and feed, a percentage of 2.12 are improper to human consumption, compared to 2009, when all samples analyzed have not exceeded the ML set in legislation for HM in food and feed.
