Cat food testing released in October 2026 has found heavy metals, pesticide residues and plastic-related chemicals in products sold across a wide range of brands.
The Clean Label Project said it analysed 100 top-selling cat food products across 62 brands, testing for more than 122 environmental and industrial contaminants, including lead, arsenic, cadmium, mercury, phthalates, pesticides, glyphosate and acrylamide.
The findings do not amount to a recall, and the organization said the testing does not determine whether a specific product will make a cat sick.
However, the results have renewed questions about how contaminants are monitored in pet food and what information is available to consumers on standard product labels.

What the cat food testing found
The analysis covered dry, wet, air-dried and freeze-dried products, allowing researchers to compare contamination patterns across different formats.
Clean Label Project reported that dry cat food carried roughly three times more lead than wet or air-dried products in its testing.
Fish and seafood-based recipes showed a different concern, with the organization reporting substantially higher mercury levels than foods made with other proteins.
In its wet-food results, Clean Label Project said fish-based products contained about 28 times more mercury than wet foods made with other proteins.
The group also reported that DEHP, a phthalate associated with plastic materials and potential hormone-related health concerns, was detected in nearly half of the products tested.
DEHP levels were higher in canned and pouch products than in bagged products, according to the project’s published findings.
Glyphosate was another focus of the analysis.
Clean Label Project said products with more plant ingredients among the first 10 listed ingredients generally showed higher glyphosate levels, while each additional plant ingredient in that group was associated with an increase of about 40 per cent.
Why the results are not a recall
The report identifies the presence and relative levels of contaminants, but it does not establish that any particular brand or product is unsafe to feed.
Each product was tested from a single batch, meaning the results cannot show how contamination may vary between production lots.
Clean Label Project also acknowledged that its rankings are based on cumulative contaminant scores and are not an assessment of nutritional adequacy or a medical finding.
The organization’s own product list states that a food’s absence from its “Clean Sixteen” does not necessarily mean the product exceeds federal or state limits.
That distinction matters for Canadian shoppers because detecting a chemical is not the same as proving that exposure from a particular serving creates a health risk.
Pet owners should not abruptly change a cat’s diet solely because a product was not included among the project’s top-ranked foods.
What Canadian pet owners should know
Canada does not regulate pet food in the same comprehensive way it regulates food intended for human consumption.
The Canadian Food Inspection Agency says its oversight of pet food is primarily focused on import and export requirements for animal products and by-products, while other federal departments may oversee specific ingredients or claims.
The Public Health Agency of Canada also warns that pet food can carry germs such as Salmonella and E. coli, particularly when products are raw, freeze-dried or dehydrated.
It recommends cooked pet food, including canned food, processed kibble and fresh cooked food, as safer choices from a germ-exposure perspective.
Those recommendations address bacterial risks and do not resolve the separate questions raised by the contaminant testing.
Canadian consumers should therefore treat the new analysis as information about testing transparency rather than evidence that all cat food is dangerous.
How to make a safer cat food choice
Veterinarians can help owners select food based on a cat’s age, health conditions, weight, allergies and nutritional requirements.
- Check whether the manufacturer conducts routine testing for heavy metals, pesticides and packaging-related chemicals.
- Keep the product packaging and lot number in case a safety notice is issued.
- Use caution with raw, freeze-dried and dehydrated products because they can carry bacterial risks.
- Consider rotating approved protein sources where appropriate, particularly if a cat eats fish-based food as its main diet.
- Do not make a sudden diet change without veterinary advice, especially for cats with kidney, urinary, digestive or other chronic conditions.
Clean Label Project published “Clean Sixteen” lists for dry and freeze-dried food and for wet food, highlighting products with the lowest cumulative contaminant scores in its sample.
The lists are not official Canadian safety certifications and should not replace veterinary advice or a manufacturer’s nutritional adequacy information.
What happens next
The testing is likely to increase pressure on manufacturers and retailers to disclose more about contaminant screening and packaging controls.
For now, there is no verified Canadian recall connected to this October 2026 analysis.
Consumers should continue checking Canada’s official recalls database for product-specific notices and contact a veterinarian if a cat develops persistent vomiting, weakness, loss of appetite, difficulty walking or other concerning symptoms.
Pet owners who suspect a product caused illness should keep the packaging, record the lot code and speak with both a veterinarian and the retailer or manufacturer.
Canada’s public health guidance also recommends washing hands after feeding pets and cleaning bowls, utensils and surfaces used with pet food.
Frequently Asked Questions
Was there a cat food recall in Canada because of this testing?
No verified Canadian recall has been linked to the October 2026 contaminant analysis. It was a testing report, not a government recall notice.
What contaminants were found in the cat food analysis?
The testing examined heavy metals including lead, arsenic, cadmium and mercury, along with phthalates, pesticides, glyphosate and acrylamide.
Is dry cat food more dangerous than wet food?
The testing found roughly three times more lead in dry food than in wet or air-dried products, but it did not prove that any food format is inherently unsafe or that a specific product will cause illness.
Why were fish-based cat foods highlighted?
The analysis reported much higher mercury levels in fish and seafood-based products, particularly wet seafood foods, compared with foods made with other proteins.
What should Canadian cat owners do now?
Do not make sudden diet changes without veterinary advice. Check official recall notices, keep packaging and lot numbers, ask manufacturers about contaminant testing and seek veterinary care if a cat becomes ill.
Fact-Checked: Key findings were checked against Clean Label Project testing materials and Canadian government pet food safety and regulatory guidance.
