Study: Mislabeling a widespread issue in the pet food industry by The Good Shopping Guide | Jul 13, 2018 | Ethical Shopping Blog | 0 comments A new study published in the journal BMC Veterinary Research has found further evidence of widespread mislabeling of pet food products. The study, led by Rebecca Ricci and co-authored by several others, sheds further light on what is considered an ongoing issue within the pet food sector: namely, the problem of contamination and the problem of mislabeling protein sources. Using microarray analysis, the researchers assessed 40 products (9 dry novel protein diets, 22 wet novel protein diets, 6 dry hydrolyzed protein diets and 3 wet hydrolyzed protein diets). Of the 40, only 10 presented ingredients that matched the label while 5 did not contain any trace of the declared animal species. It was found that, in the majority, 23 products contained some presence of undeclared animal species. Furthermore, the researchers found that undeclared animal species was more often found in dry than wet pet foods. In short, 13 out of 14 brands were found to have at least one product guilty of mislabeling. Mislabeling seems to be a widespread issue in pet foods used as elimination diets. Contamination can occur in all types of products used for the purpose, although dry NPDs are the main issue. Due to the high risk of contamination, particular attention should be given to both the selection of raw material suppliers and the production process.
