The tiny duchy of Luxembourg became the eighth EU state to be affected after eggs contaminated with the chemical fipronil were found in Belgium, the Netherlands, Germany, Sweden, Switzerland, Britain and France.
Luxembourg said it had informed the European Commission, which runs the bloc’s food safety alert system.
Discount supermarket chain Aldi had withdrawn suspect batches sold in Luxembourg but “contaminated eggs were sold on the Luxembourg market”, the government announced.
One batch contained so much fipronil it was unsafe to be eaten by young children, said the government statement. The batch posed no threat to consumers, it added.
