Microplastics Found In Majority Of Pet Food Brands, Study Warns

Microplastics have been found in more than three-quarters of pet food products tested in a new study by researchers at the Universities of Sussex and Exeter.

The research identified microplastic contamination in 16 of the 19 pet food brands examined, including several well-known products.

Researchers found that lower-cost "value range" foods for cats, dogs and wild animals generally contained higher levels of microplastics than more expensive alternatives.

Microplastics are tiny plastic particles measuring less than five millimetres in size and have been detected in food, drinking water and the wider environment.

The study also found that while dry pet food contained higher concentrations of microplastics, wet food could result in greater daily intake because animals typically need to consume more of it to meet their nutritional needs.

Scientists are now calling for new regulations requiring processed food manufacturers to test for microplastic contamination, similar to existing checks for chemical pollutants.

Professor Tamara Galloway, Professor of Ecotoxicology at the University of Exeter, said:

"Our results are a reminder that our pets are exposed to the same chemical pollutants as ourselves."

Professor Fiona Mathews, Professor of Environmental Biology at the University of Sussex, added:

"Pets may be inadvertently spreading plastic pollution through their food and faeces, affecting wildlife and the wider environment."

Researchers say the source of the contamination remains unclear and further investigation is needed to determine whether ingredients, packaging or manufacturing processes are responsible.

A spokesperson for UK Pet Food said commercial pet food products comply with all current regulations and food safety standards, adding that microplastics are a broader environmental issue found across many aspects of daily life.

The organisation said it continues to work with regulators and scientists as research into the effects of microplastics develops.

Veterinary charity Blue Cross said more research is needed to understand how pets are exposed to microplastics and what long-term impact this may have on their health.
