Taste of the Wild uses food-grade BPA-free packaging for its High Prairie Grain-Free Dry dog food, and other food products. BPA is a harmful chemical. In the past, people would use BPA-plastic packaging for a lot of things. That includes food packaging as well. However, people have observed that such type of packaging is harmful. Thus, Taste of the Wild avoids such packaging and uses only BPA-free food-grade plastic packaging.
