Örjan Brinkman is the president of the Swedish Consumers' Association and the pan-European organization BEUC. He says the latest scandal is proof that there is not enough regulation and monitoring.
"Industry can't afford to do it itself, it needs to be in law," says Örjan Brinkman.
So far in Sweden the insecticide has only been found by one wholesaler. But the Swedish authorities admit they cannot keep track of everything.
Petra Fogelberg at Sweden's Food Agency says they keep track of what is happening in the world, and if they get reports from other countries then they follow up to trace the substances in Sweden, but that it is impossible to keep track of all forbidden substances.
The eggs in question come from the Netherlands. The EU Commission has called a crisis meeting to discuss what action to take. The substance has been found in 15 EU countries and Switzerland and Hong Kong.
The Swedish Food Agency says that the amount of insecticide detected in the eggs from Netherlands is not a level dangerous for humans.
