THE HAGUE, Netherlands (AP) — Dutch and Belgian authorities are carrying out raids as part of a criminal investigation into the illegal use of pesticide at poultry farms.

Marieke van der Molen of the Dutch National Prosecutor's Office says investigators from the country's food safety watchdog are conducting the raids in the Netherlands. She did not provide details on which companies or individuals were targeted.

Van der Molen says the Dutch raids on Thursday are part of a joint action with Belgian authorities.

Dozens of producers in the two countries are being investigated for eggs containing Fipronil, which is potentially dangerous. However, no cases have been reported of people falling sick.

As a result of the scandal, millions of eggs have been pulled from supermarket shelves in Germany as well as Belgium and the Netherlands.
