In France, Agriculture Minister Stephane Travert said that tests on imported eggs contaminated with pesticide show no risk to public health.
Non-EU Switzerland is also affected.
The EU's executive Commission said on Friday that contaminated eggs have been found at producers in four countries; Belgium, France, Germany and the Netherlands.
The insecticide is said to be harmful to the liver, kidneys and thyroid glands if enough are eaten.
The EU on Friday called an emergency meeting to stop "blaming and shaming" over the insecticide- tainted eggs scandal as it emerged for the first time that the crisis had spread to Asia.
Eggs or egg products from those producers have reached Austria, Britain, Denmark, Ireland, Italy, Luxembourg, Poland, Romania, Slovenia, Slovakia and Sweden, as well as Switzerland and Hong Kong outside the EU. 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).
But the World Health Organization said that, when digested in large quantities, the chemical could cause harm to the kidneys, liver and thyroid glands.
"The Centre for Food Safety is now inspecting eggs coming from Europe closely, no matter at the import, or at the retail level", Chan said.
A spokeswoman in Brussels said the situation was "evolving by the day", as criminal investigators continued to hold two men arrested on Thursday for fraud following a series of raids in Belgium and the Netherlands.
"Because the content is illegal, Danæg Products must withdraw the eggs from their customers".
Eggs, coming mainly from the Netherlands, were found to contain fipronil, a substance used to kill lice and ticks on animals that is banned by the European Union for use in the food industry.
