Executive Summary: The Clean Label Project, a US non-profit, reported on 6 October 2026 that tests of 100 best-selling cat foods across 62 brands detected lead in 99 percent of samples, cadmium in 96 percent and arsenic in 94 percent, with dry food showing roughly three times more lead than wet. Romanian veterinary officials responded that pet food sold in Romania is tested under strict European Union standards. The exchange has revived the question sitting behind every contaminant finding: what is AAFCO and what does its approval actually guarantee.

What Happened
The Clean Label Project’s latest investigation drew coverage on 6 October 2026 after the RO Times reported its findings and the response from Romanian authorities. For readers asking what is AAFCO’s role in this debate: AAFCO, the Association of American Feed Control Officials, sets model labeling and nutrient standards for pet food in the United States, but maximum allowed levels for contaminants such as heavy metals sit with FDA and state regulators, and critics say those limits do not exist for pet food the way they do for human food.
The study tested 100 of the best-selling cat foods across 62 brands. Lead was detected in 99 percent of samples, cadmium in 96 percent and arsenic in 94 percent. Dry food contained approximately three times more lead than wet food. Some samples also showed residues of pesticides and chemicals associated with plastics, which the organization links to long-term health risks including renal damage and central nervous system reactions.
Background: Detection Is Not a Recall
The findings describe detection of trace elements, not unsafe products or a recall, and no illness data accompanies the report. The Clean Label Project frames the results as evidence of a regulatory gap; the strategy works because the numbers are easy to quote, but the distinction between detection at any level and a health hazard at measured doses is where the scientific argument actually sits. Owners worried about contaminants often arrive through searches about foods toxic to cats, which address a different problem — acutely dangerous ingredients such as onions or lilies — rather than chronic low-level exposure to elements that occur naturally in the food supply.
Romanian veterinary officials, responding to the report’s regional pickup, emphasized that pet food sold in Romania falls under strict European Union standards. Testing is carried out primarily by the Veterinary Sanitary Authority, including laboratories at the Institute of Public Veterinary Hygiene and Health in Bucharest. Officials said products are regularly sampled for bacteria such as salmonella as well as heavy metals and pesticides, and that non-conforming products are withdrawn from the market.
Industry Context
The episode lands in the middle of a transatlantic standards conversation. In the United States, pet food contaminant limits are fragmented, and advocacy outlets such as Truth About Pet Food used the same report to renew the question of whether FDA will ever set maximum allowed levels for heavy metals, pesticides and plastics in pet food. In the European Union, feed and pet food contamination limits are codified, which is why the Romanian response reads as reassurance rather than alarm.
For brands, the commercial layer is just as real. The 62 brands tested sit inside a crowded premium shelf that GPI’s company directory indexes through 110 entries under the cat food brand directory combination. Any retailer or importer fielding customer questions now has two reference frames to explain — US advocacy testing and EU regulatory sampling — and the gap between them is where confusion spreads.
Market & Business Impact
No recalls, illnesses or regulatory actions were announced. The impact runs through consumer sentiment and procurement. Heavy-metal headlines tend to push cat owners toward brands that publish contaminant testing, which favors manufacturers with in-house QA capability and validated supplier chains. Dry food’s higher measured lead load — about three times the wet food figure in this sample — may also feed the ongoing format debate, where wet and fresh formats have been gaining shelf share on hydration and ingredient claims.
For distributors and importers in EU markets, the Romanian statements are the operative facts: sampling regimes exist, non-conforming lots are pulled, and the EU framework — not US advocacy reports — governs what can be sold. For US-market brands, the open question is whether state-level or federal limits follow the publicity.
Companies & Brands Involved
The Clean Label Project is a US-based non-profit that tests consumer products for contaminants and publishes the results. The 62 brands tested were not individually named in the coverage available. Romanian officials spoke for the national testing system rather than any manufacturer. Brands working through contaminant and labeling questions can be compared via the GPI compare tool and profiled through the GPI company directory.
Data & Evidence
100 products, 62 brands tested (Clean Label Project, reported 6 October 2026). Lead detected in 99% of samples, cadmium in 96%, arsenic in 94% (Clean Label Project, reported 6 October 2026). Dry food approximately 3x more lead than wet food (Clean Label Project, reported 6 October 2026). Romanian testing by the Veterinary Sanitary Authority, including Bucharest laboratories, with regular sampling for salmonella, heavy metals and pesticides (RO Times, 6 October 2026).
What This Means for the Pet Industry
GPI’s read: detection studies are becoming a recurring feature of the pet food news cycle, and the companies that handle them well publish their own testing data rather than waiting to be asked. The actionable divide is regulatory: EU sellers answer with the Veterinary Sanitary Authority’s framework, while US sellers still operate without maximum contaminant levels, which keeps the AAFCO and FDA debate alive.
Key Takeaways
- The Clean Label Project tested 100 best-selling cat foods across 62 brands and reported lead in 99 percent of samples, cadmium in 96 percent and arsenic in 94 percent.
- Dry food showed roughly three times more lead than wet food in the same sample set.
- Some samples also carried pesticide residues and plastic-associated chemicals, which the organization links to long-term renal and neurological risks.
- Romanian veterinary officials said pet food in Romania is tested under EU standards by the Veterinary Sanitary Authority, with non-conforming products withdrawn.
- No recall or illness data accompanies the findings; the report renews the US debate over FDA and AAFCO contaminant limits.
Frequently Asked Questions
What did the Clean Label Project find?
The non-profit tested 100 best-selling cat foods from 62 brands and reported detecting lead in 99 percent of samples, cadmium in 96 percent and arsenic in 94 percent, with dry food containing about three times more lead than wet food.
Does this mean cat food is unsafe?
The findings describe detection of trace elements, not a recall or illness data. Health risk depends on dose and exposure, which the reported coverage does not quantify. Romanian officials pointed to EU testing standards, and no regulatory action followed.
What is AAFCO?
The Association of American Feed Control Officials, the body that sets model labeling and nutrient standards for pet food in the United States. Maximum contaminant levels for heavy metals in pet food are not established the way human-food limits are, which is the gap critics highlight.
How is this different from foods toxic to cats?
Foods toxic to cats are ingredients that cause acute poisoning, such as onions or lilies. The Clean Label Project findings concern trace contaminants that accumulate with long-term exposure, a different risk profile.
Who tests pet food in Europe?
In Romania, the Veterinary Sanitary Authority and its laboratories, including the Institute of Public Veterinary Hygiene and Health in Bucharest, sample products for bacteria, heavy metals and pesticides under EU standards.
