Free range eggs from Spain were seen on sale at a grocery store in east Hong Kong Island Saturday. The scandal has also spread beyond Europe as tainted eggs have been found in Hong Kong as well.
She said the EU's "priority remains to manage the situation, to continue to coordinate and to reassure our citizens".
The EU countries affected are Belgium, the Netherlands, Germany, France, Sweden, Britain, Austria, Ireland, Italy, Luxembourg, Poland, Romania, Slovakia, Slovenia and Denmark, along with non-EU Switzerland, and Hong Kong, commission spokesman Daniel Rosario said.
France's Agriculture Minister Stéphane Travert said about 250,000 affected eggs had been sold in the country since April, adding that all products containing eggs from contaminated farms would be taken off the shelves. A US egg producer has recalled more than 200 million chicken eggs apparently contaminated with salmonella bacteria after hundreds of people have become sick, according to the US Food and Drug Administration (FDA). Denmark said on August 10 it had found a haul of 20 tons of tainted eggs, imported from Belgium.
Danish food safety authorities say 20 tons of boiled and peeled eggs linked to the pesticide scandal in the Netherlands and Belgium were sold in recent months to a distributor in Denmark, which in turn sold them to canteens, cafes and catering companies in the country.
The Agriculture Ministry says the French farm reported on July 28, as the scandal was coming to light, that Dega 16 had been used on the farm by a Belgian subcontractor, and the ministry claims no eggs concerned have been sold.
As well as dealing with the immediate food safety issue, the European Union is also seeking to calm tempers over the egg row after a series of divisive crises in the bloc in recent years, from Brexit to migration. "Information needs to be shared between (EU) member states without delay".
The Center for Food Safety (CFS) of the HKSAR's Food and Environmental Hygiene Department is "very concerned about" the matter and has implemented measures to deal with problematic eggs, Secretary for Food and Health Sophia Chan told the media.
"We were well aware of a report of the presence of fipronil in the pens of egg-laying hens in November 2016, but there was no indication at the time that fipronil itself was found in the eggs", said Schippers.
Poland said it had discovered about 40,000 eggs imported from Germany.
