In February 2015, a class action lawsuit was filed against Purina's parent firm, Nestle Purina Petcare Company, alleging that Purina Beneful dog food had sickened or killed thousands of pets. The plaintiffs claim that their dogs suffered vomiting, diarrhea, internal bleeding, liver problems and kidney failure, reports Cincinnati's WLWT News.
Although the case has not been decided as of October 2015, the allegations against Purina include a claim that the company knowingly used a toxic chemical, propylene glycol, in its food, states WLWT News. The plaintiffs also claim that the food contains high levels of mycotoxins, which are toxic substances produced by fungi found in grains. Nestle Purina denies the allegations and has not issued a recall of the food.
