A very small number of eggs contaminated with a toxic insecticide reached the UK earlier this year. Some of the eggs, which originated from the Netherlands, were also found in France, the country's agricultural ministry said.
The UK's food standards agency say the risk to the public is very low. The agency is "urgently investigating" the issue, but to the best of their knowledge, the affected products are no longer on shelves.
it says there is no need for people in Britain to avoid eating eggs and any potential exposure is unlikely to harm. The revelations come after the supermarket chain Aldi withdrew all eggs from sale in its stores in Germany last week.
Tests had shown the chemical fipronil, which can harm kidneys, liver and thyroid glands, was found in the eggs.
Fipronil can treat lice and ticks in chickens, but should not be used on food-producing animals because of its toxicity.
Shops in Belgium, the Netherlands and Germany, have removed the eggs from sale as a precaution.
About 180 poultry farms in the Netherlands have also been temporarily shut in recent days while investigations are held.
