There are a growing number of pet owners who feed pets on raw, which means, "uncooked" meat and bones. William Burk, a pet food specialist from the Food and Drug Administration (FDA) , believes that feeding raw meat to pets is against its goal of protecting the public from health dangers; besides, raw meat and bones do not have all the required nutrition(营养)that a pet needs every day. Recognizing how popular these foods are, the FDA has provided guidelines for producers of pet foods that contain uncooked meat for dogs, cats, and other pets. The guidelines give rules to protect pet owners and pets from dangers about food safety and lack of nutrition. Pet owners who feed raw meat and bones should deal with these products very carefully to protect themselves against possible dangers, says Burk. Just as when preparing foods for humans, use hot water and soap to wash hands, containers, and surfaces that come into contact (接触) with the food. Don't put your hands near your mouth until you've washed them, and don' t allow your pet to touch your face right after it has eaten meat. If owners choose to feed bones to their pets, they should watch their pet carefully when it is eating bones. Burk also says, "If the pet eats a big piece of bone that won't pass through the digestive system(消化系统) , it could kill the pet."
