Update on Fipronil in Eggs. food.gov.uk. September 21, 2017. We continue to trace the distribution of eggs from farms in the Netherlands and Belgium affected by Fipronil. Since our previous update, one additional product has been withdrawn, as detailed in our updated withdrawal list. This is a waffles product, sold in smaller retail stores and catering outlets. 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 maximum residue level. The FSA continues to  work with the European Commission and we are being updated on investigations by other member states as further information comes to light.

It remains very unlikely that there is any risk to public health, but as Fipronil is not authorised for use in food producing animals, we continue to track down implicated food products and ensure that they are removed from sale where they breach the 15% limit. There is no need to change how you buy or consume eggs.
As a precaution, eggs from a substantial proportion of the UK flock size have been tested for Fipronil. No Fipronil has been found, and testing will continue.
Investigations are on-going, and we will continue to publish updates on a regular basis.
