Some animal treats may have made some dogs and cats sick or even killed them.

There was a recall back in January, of some of those chicken jerky treats which were made in China. In a story from News 10 ABC, the mystery of why these treats are killing pets is still going on, with research being done by the Food And Drug Administration. Much of the research is being done in the New York State Agriculture And Markets Food Safety Lab in Albany.

This research has been ongoing for about six years after some pet owners reported the animals were getting sick. They found some potential antibiotics contaminating the jerky treats. They’re not allowed in poultry products. The findings happened in January, which is when the treats were recalled. It’s still not certain if that’s what caused the illness or deaths of the animals.

According to an article in Timenewsfeed.com on Tuesday, the Chinese jerky treats are what caused a mysterious outbreak which killed around 600 pets, mostly dogs and a small number of cats. The companies that withdrew  some of those products were Milo’s Kitchen and The Nestle Purina PetCare Company.
