The Food Standards Agency (FSA) has added four more products to its list of withdrawn products over Fipronil, as the investigation to track down implicated food products continues.

Products include one batch of Profiteroles au beurre and two batches of Profiteroles Butter withdrawn by Pidy UK Ltd, and Wafel Janssen BV 6 Toasting Waffles withdrawn by WM Morrison’s.

Fipronil is an insecticide that was found to have contaminated eggs and egg products in a number of EU countries.

According to FSA, products must be removed from sale if the amount of implicated egg is more than 15% of the final product.

Food businesses must comply with this or show that the egg ingredient used is compliant with the EU’s maximum residue level.

FSA says that it remains very unlikely that there is any risk to public health, but as Fipronil is not authorised for use in food producing animals, the agency will continue to track down implicated food products and ensure that they are removed from sale where they breach the 15% limit.

The agency is also working with the European Commission and is being “updated on investigations by other member states as further information comes to light.”
