Cat food investigation finds toxic contaminants in almost every brand

(CNN) – A new investigation into cat food has found toxic chemicals in almost every type and brand.

One hundred of the best-selling cat foods, including wet, dry, and air-dried or freeze-dried, have been tested for more than 120 contaminants.

Toxic plastic contaminants, the herbicide glyphosate and heavy metals such as lead, mercury and arsenic were found in all types of foods tested.

Metal levels according to brands

Among cat food samples from 62 brands, lead was found in 99% of samples. Cadmium, harmful to the kidneys and bones, was found in 96% of samples. Arsenic was found in 94% of samples.

Differences depending on protein type

The report, by the nonprofit Clean Label Project, finds that fish and seafood proteins, especially wet versions, typically contain the most mercury and cadmium.

Chicken versions had higher levels of lead and herbicides.

Nearly 85% of poultry foods met the Clean Label Project purity standard, compared to 25% of fish and seafood products.

Report Recommendations

According to the report, cat owners should try to vary their pet’s diet.

Moist or air-dried products are preferable to dry foods for less lead exposure.

Avoiding foods with plants in the top ten ingredients could help reduce pesticide exposure.
