Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, whether her Department has made an assessment of the presence of fipronil and its metabolites in drinking water in the UK stemming from pet parasite treatments; and whether she can confirm that UK drinking water is free from those chemicals.

Regulation 4 of The Water Supply (Water Quality) Regulations 2016 stipulates that ‘drinking water must be wholesome meaning it does not contain any substance at a concentration or value which is harmful to human health’.

Information on veterinary medicines in drinking water is available in a Drinking Water Inspectorate report.
