Fifteen EU countries as well as Hong Kong and Switzerland have received eggs contaminated with the insecticide Fipronil. The commission will hold a meeting with ministers and regulators on September 26. Its food safety chief has called countries to stop "blaming and shaming" each other. A row has erupted over how long Belgian and Dutch authorities have known about the contamination. Fipronil is a substance used to kill lice and ticks on animals that is banned by the EU for use in the food industry.
