'We have now established that more eggs from affected farms than previously identified came to the UK.
The Food Standard Agency (FSA) are continuing to withdraw egg-based products from British supermarkets after it was found that more than 700,000 eggs were implicated in the European Fipronil contamination scandal.
In response, Morrisons, Sainsbury's, Waitrose and Asda in the United Kingdom had withdrawn a total of 11 products - including sandwiches, sandwich fillers and salads - from sale. We regularly inspect and conduct sampling of the eggs and hen farms to ensure compliance with our food safety and animal health standards and requirements.
Health minister Sophia Chan said Saturday authorities were "strengthening" inspections of eggs from Europe.
Eggs containing the banned insecticide Fipronil have so far been found in more than half the European Union nations, along with Switzerland and Hong Kong, officials said.
Twenty tonnes of the contaminated eggs have been sold, according to the Denmark's food safety authority.More news: 'Let's See' What N. Korea Does With Guam
The chemical, Fipronil, is not authorised for use as a pesticide around food-producing animals as it can make its way into milk and eggs.
Last week, the UK's FSA said around 21,000 eggs were shipped to the country; today, it said it was "likely that the number of eggs that have come to the United Kingdom is closer to 700,000". The substance is used to treat lice, fleas and ticks, and in large quantities, it can cause liver, kidney and thyroid gland damage.
Around 85% of eggs consumed in Britain are laid in the UK.
Two non-EU countries, Switzerland and Hong Kong, have also received contaminated products originating from affected poultry farms in Belgium, the Netherlands, Germany and France that have been treated with fipronil.
The eggs scandal that has led to millions of eggs being withdrawn from supermarket shelves in a number of European nations has reached Danish shores.
Similarly, early last month, a small quantity of liquid pasteurised egg - with a "use-by" date of July 20 - was supplied to a number of food businesses for use in bakery products, the FSAI added.
