Hong Kong, Switzerland and 15 European Union countries have all received eggs contaminated with the chemical fipronil, which can harm human health, the European Commission said.
With concern going global, the commission said it had now called a meeting of ministers and food safety chiefs from affected EU countries, setting a provisional date of September 26.
"Blaming and shaming will bring us nowhere and I want to stop this," Vytenis Andriukaitis, the European Commissioner for health and food safety, told AFP as he announced the meeting.
Dutch Health Minister Edith Schippers, speaking publicly about the matter for the first time, admitted late Thursday that errors had been made in the government's handling of the crisis.

Fipronil is commonly used to get rid of fleas, lice and ticks from animals but is banned by the European Union from use in the food industry.
The EU insists there is no threat to human health, but the World Health Organisation (WHO) says that when eaten in large quantities it can harm people's kidneys, liver and thyroid glands.
European Commission spokeswoman Mina Andreeva said that "this is not, let's be clear, a crisis meeting" and it is being held next month to get "distance to the events".
Brussels said the 15 EU countries affected were Belgium, the Netherlands, Germany, France, Sweden, Britain, Austria, Ireland, Italy, Luxembourg, Poland, Romania, Slovakia, Slovenia and Denmark, along with non-EU Switzerland.
But it also announced that Hong Kong had received some tainted eggs, with the southern Chinese city becoming the first place in Asia known to be affected.
The EU is seeking to quickly end the egg feud and maintain unity after a string of crises including Brexit, a migration influx and debt in the eurozone.
