The Food Standards Agency says it is investigating how eggs that may have been contaminated with a toxic insecticide ended up on United Kingdom supermarket shelves.
According to Schmidt, there were no more contaminated eggs in German supermarkets. All eggs in Belgium were blocked from sale.
The scare over the use of insecticide fipronil and how it got into batches of eggs has widened - with United Kingdom government agencies issuing a warning that a small number of contaminated eggs have got into Britain's food chain and have already been consumed.
"We are now testing chicken meat in the poultry farms where eggs were infected to determine whether the meat is contaminated as well", Tjitte Mastenbroek, spokesman for food security agency NVWA, told AFP.
Following revelations last week that eggs in the Netherlands had been found to be contaminated with Fipronil, Schmidt has estimated that 12 of Germany's states were affected.
The decision to scrap food product boards in 2014 has also made the sector vulnerable, Schuttelaar said.
The lots were sent to establishments in the Vienne and ME et Loire regions, southwest of Paris, the ministry said. Supermarkets have since pulled millions of eggs from their shelves.
Last week FoodIngredientsFirst revealed how the Dutch food and product safety board (Nederlandse Voedsel- en Warenautoriteit, or NVWA) banned 180 poultry farms from sending their eggs to market because they may be contaminated with the pesticide - which is used to treat lice and ticks in chickens and some tests show that it can harm kidneys, the liver and thyroid gland in people.
The contamination is alleged to have come from a product meant to eradicate red lice in breeding farms, which was apparently used despite European Union regulations banning such products in animals destined for the human food chain.
Eggs tainted with the insecticide were discovered in Belgium in early June, and in the Netherlands.
Belgium and Dutch authorities have since vowed to offer full transparency on their national investigations. Questions have been raised as to why alerts went out long after the finding.
Hard-hit Germany on Tuesday called on Belgian and Dutch authorities to quickly shed light on what it termed a "criminal network" involved in the contamination of eggs with fipronil.
