Fifteen EU countries as well as Hong Kong and Switzerland have received eggs contaminated with the insecticide fipronil, the European Commission says.
The commission will hold a meeting with ministers and regulators on 26 September.
Its food safety chief has called countries to stop "blaming and shaming" each other.
A row has erupted over how long Belgian and Dutch authorities have known about the contamination.
Eggs, coming mainly from the Netherlands, have been found to contain fipronil, a substance used to kill lice and ticks on animals that is banned by the EU for use in the food industry.
It is thought it was used to combat lice in some chicken farms, affecting the eggs of laying hens.
What do we know about the Europe egg scare?
The insecticide can damage people's kidneys, liver and thyroid glands if eaten in large quantities. However, food standards agencies are playing down the risks for anyone who has already eaten the tainted eggs.
Which countries are affected?
Farms were shut down in the Netherlands, Belgium, Germany and France after authorities confirmed that fipronil had been used, European Commission spokesman Daniel Rosario said on Friday.
The EU countries that have received the eggs are the UK, Sweden, Austria, Ireland, Italy, Luxembourg, Poland, Romania, Slovenia, Slovakia and Denmark. Non-EU Switzerland is also affected.
