Just like Nigeria’s noodle scare, beans scare and chicken scare; an egg scare is rocking the whole of Europe.

Countries are pulling eggs from the shelves even as Netherlands remains poised to cull millions of chickens.

The fear is that some eggs have been contaminated and people have bought and consumed some of them.

Britain said 20,000 of the contaminated eggs have already been sold and consumed, according to its Food Standards Agency.

The eggs were imported between March and June, it said.

The scare began in Belgium in June after it was learnt that a dangerous insecticide, fipronil had been used to treat pests on chickens.

The chemical is potentially harmful to humans as well.

Fipronil is commonly used in veterinary products to get rid of fleas, lice and ticks. But it is banned from being used to treat animals destined for human consumption, such as chickens.

The substance is absorbed into the skin or feathers of chickens and then passes into the eggs.

In large quantities, the insecticide is considered “moderately hazardous” by the World Health Organization, and can have dangerous effects on people’s kidneys, liver and thyroid glands.

France also said Monday that some insecticide-tainted eggs may have entered their countries, as the egg contamination scare spreads in Europe.

As a result, supermarkets in Germany, the Netherlands and Belgium have pulled millions of eggs from the shelves since Belgium gave the European Commission the first notification on July 20, while retailers in Sweden and Switzerland have followed suit.

The Commission said Monday that under its EU rapid alert system it had been determined that eggs under suspicion of contamination had also been distributed to France and Britain via Germany.
