The Singapore Agri-Food and Veterinary Authority has destroyed eggs valued at approximately $700,000 as a result of alleged antibody residues.

This action denotes the risks associated with extra-label use of antibiotics in flocks producing eggs. Regulatory authorities worldwide are under pressure from consumer groups to conduct routine assays of livestock products using highly sensitive analytical equipment.

The action in Singapore is reminiscent of the wide-scale surveillance for nitrofuran residues in poultry from Southeast Asian countries during the late 1990s.

It is anticipated that the Food and Drug Administration will implement a program to assay eggs produced in the U.S.
