Veterinary Products in Waterways

Farmers are suffering at the hands of this Government, and with them so suffers our environment. Will the Minister take this opportunity to reassure the House that her colleagues in the Department for Environment, Food and Rural Affairs are doing everything they can to support our farmers as they balance the agricultural and environmental needs of the land? Will she also ensure that due consideration is given to the restoration of the SFI scheme, so that we can keep making progress on our environmental goals, hand in hand with farmers, and not be distracted from the harms of damaging products such as the neonics that I have been talking about by losing our much needed local and rural allies?

I am aware that this speech has been slightly doom and gloom, but I will now turn to what we can do as an alternative. Research has shown that the likes of coconut oil, citronella oil, good old lavender and eucalyptus provide good natural and, most importantly, non-toxic alternatives for flea and tick repellents. The market is awash with collars for cats and dogs infused with these essential oils, which are both practical and natural. There has been very little emphasis on these solutions. We should be doing much more to promote the benefits of these chemical-free remedies.

As seen in recent developments in Switzerland, where the Government are carrying out water testing, there is a clear need for environmental impact assessments of the use of fipronil and imidacloprid. These should be launched as a matter of urgency, and I would welcome the Minister’s reflections on this point. We Liberal Democrats have called for any emergency authorisations of neonics to be revoked, and for the introduction of tighter restrictions on their use. I invite the Minister to comment on the state of play and whether there is a serious appetite in the Government to address this issue.

It is clear that we have a serious challenge on our hands. As the hon. Member for Truro and Falmouth (Jayne Kirkham) said, these products are advertised widely and sold ubiquitously. I am not blind to the fact that these products have brought undeniable benefits in pest control, but their unintended consequences serve as a stark reminder of the need for sustainable and nature-friendly practices. I genuinely believe that there is a desire to do more to regulate these highly toxic chemicals. Lawmakers were right to impose a blanket ban on fipronil and imidacloprid in agricultural settings in 2017 and 2018. The will should be there to ensure that these products cannot be allowed to continue damaging our freshwater ecosystems. Further regulation is the only way forward to remove harmful contaminants and arrest the degradation of aquatic fauna in this country’s waterways.

The Government also need to go further and faster in regulating our waterways and the water companies damaging them overall. The Water (Special Measures) Act is a good first step, but the Government can and must do more. Ofwat is failing in its duties. The time has come for a new clean water authority to replace it as we up our game in protecting our precious waterways. I see no reason why reforms designed to keep neonics out of our waterways cannot come hand in hand with our push to keep sewage and other contaminants and pollutants out of our waterways.

In the short term, for neonics, restrictions should be placed on the trade of fipronil and imidacloprid, with the only exception to their continued use coming under strict conditions of prescription only by veterinary medical professionals and for a limited time period. We know that Amazon and the over-the-counter market in pet stores can lead to the propagation of those products in our natural environment, so restrictions would make some sense.

When the time allows, a ban for all other usage should certainly be in the Government’s scope. It is clear that decisive action must be taken on this matter. Could the Minister shed some light on whether the Government would be willing to assess the potential merits of moving in that direction? From all that I have seen, that appears the prudent—and perhaps only—direction to take.

On our wider work on neonics, before Christmas we made a written ministerial statement talking about how we wanted to ensure a complete ban in the use of the emergency authorisation. The hon. Lady will know that I declined this year’s emergency authorisation for the use of Cruiser pesticides. That demonstrates the Government’s commitment to tackling some of the concerns that are widely held.

The quality of our water is, of course, essential for supporting ecosystems, providing clean drinking water and producing our food. Maintaining healthy and clean water sources is vital to achieving the Government’s mission for sustainable economic growth, but the public are also concerned about chemicals used for the treatment and prevention of fleas and ticks for pets in UK waterways. The Government are committed to understanding the impacts of veterinary medicines entering our environment.

Speaking more widely about water quality, the flawed water system that the Government inherited is still discharging record levels of sewage into our rivers, lakes and seas. The situation is not just an environmental failure; it is also a public health crisis, demanding our immediate and decisive action to rectify decades of neglect and mismanagement. We need a systematic approach to tackling issues that impact the whole of the drainage and waste water systems, stopping the unnecessary pressure from rainwater and sewage misuse entering the system to the point at which it is discharged into the environment.

As mentioned, the Water (Special Measures) Act 2025 gained Royal Assent on 24 February 2025, boosting the power of water sector regulators to tackle pollution. That major legislation delivers on this Government’s promise to clean up the water sector and is the most significant increase in enforcement powers for water industry regulators in a decade. The Act will give regulators new powers to take tougher and faster action to crack down on water companies damaging the environment and failing their customers. However, we do not just want to give that—oh no, we want to do so much more.

Further legislation aimed at fundamentally transforming how our entire water system operates will be guided by the findings of the Independent Water Commission, led by Sir Jon Cunliffe, which is currently conducting the largest review of the industry since privatisation. I also mention the wonderful start to the day I had today, because earlier this morning, at 9 o’clock, I met Sir Steve Redgrave and lots of young rowers from the University of Reading to discuss how we can improve our water quality for the rivers and lakes that we all love. It was a pleasure to have a cup of coffee with him very early this morning and talk about our shared ambition to clean up our rivers.

Having spoken about the importance of water quality, I will turn in detail to the topic of veterinary medicines in waterways. The Government recognise the presence of parasiticides—I nearly got away with that—in the wider environment as a significant concern, and we are actively gathering evidence on that complex, multifactorial issue. All veterinary medicines undergo a rigorous scientific assessment before approval. As the regulator for veterinary medicines, the Veterinary Medicines Directorate balances the benefits of veterinary medicine for animal health and welfare, as well as human health protection, against the associated risk, which obviously includes environmental risks. Medicines are only ever authorised if the benefit outweighs the risk. The VMD follows internationally recognised guidelines for assessing the environmental risks of veterinary medicines for all animals, including pets.

Fleas and ticks can lead to, as mentioned, discomfort and distress in pets. Those parasites can host microbes that cause disease in pets and potentially in pet owners who encounter the fleas and ticks. Topical flea treatments play a crucial role in protecting both animal and human health from fleas, ticks and disease. It is therefore essential that we take a balanced approach to the benefits of such treatments and their potential environmental impact when considering the issue.

While there is evidence of the presence of fipronil and imidacloprid in fresh waters, it is well established that, as insecticides, these substances are inherently toxic to invertebrates and we do not understand the effects that current levels are having at a population and ecosystem level. We are, however, committed to understanding the potential impacts of veterinary medicines entering the environment. The VMD has led on the formation of a cross-Government group on pharmaceuticals in the environment to develop a co-ordinated strategy to reduce the impact of the substances in the environment. The group includes key governmental bodies, including the Environment Agency, the Medicines and Healthcare products Regulatory Agency, the Health and Safety Executive and representatives from the devolved Governments. While the VMD is prioritising the development of an evidence base, working to resolve the issue will require involvement by all key stakeholders, including the pharmaceutical industry and veterinary professionals.

The work does not come without challenge and stakeholders remain divided on the way forward. Some advocate for the benefits of year-round parasiticide use for humans and animal health, others emphasise the need for more cautious use, while some push for a complete ban. Any decision to limit use must be carefully weighed against the benefits to ensure a balanced approach, as restrictions could impact animal welfare, animal health and even public health. Also, there is still a critical evidence gap in understanding the full impact of those options on both animal and human health, as well as on the environment, and that must be explored further before any regulatory action is taken.
