Two arrests have been made and millions of potentially toxic chicken eggs have been pulled from European supermarket shelves in what's been dubbed 'Europe's egg crisis'.
It started after the Netherlands warned of possible contamination with the harmful insecticide Fipronil.
Now the scare is spreading, toxic eggs have likely been exported to Germany, France, Sweden, Switzerland and Britain and millions of hens may need to be culled in the Netherlands.
Prosecutors say they've conducted eight raids in Belgium and the Netherlands, confiscating cars, seizing bank accounts and real estate.
Two suspects were arrested on Thursday: directors at Dutch company Chickfriend, which is now at the centre of the scandal.
They're charged with threatening public health.
Fipronil is a popular insecticide to treat pets for fleas and ticks but it is forbidden for use in the food chain.
