Belgium free-range eggs recalled

May 21, 2004, as reported by just-food.com: Thousands of free-range eggs have been recalled by Belgian supermarket chain Delhaize. The eggs were removed from shelves after initial testing showed abnormally high levels of cancer-causing chemicals.

The eggs tested were found to contain between two-and-a-half and five times the normal level of PCBs, environmental contaminants that have been linked to cancer, reported the Independent.

Belgian food safety agency Afsca is investigating possible causes of the contamination. PCBs are found in many foods in low concentrations and are not thought to be harmful to humans in small doses.
