Cleaning removes germs (like bacteria) and dirt from surfaces and objects. Cleaning works by using soap (or detergent) and water to physically remove germs and dirt. This process doesn’t necessarily kill germs, but by removing them, cleaning lowers the number of germs and the risk of spreading infection.
Disinfecting kills germs on surfaces and objects. Disinfecting works by using chemicals, such as bleach, to kill germs. This process doesn’t necessarily clean dirty surfaces and objects or remove germs, but by killing germs after cleaning, disinfecting can further lower the risk of spreading infection.

Common sense must prevail when handling raw meat. You do this all the time when you prepare a meal for the family. After handling raw meat for your pets, do wash your hands before eating your own food. Sterilize any knives, surfaces or utensils used in the preparation or handling of your pets' food. We recommend using a stainless steel or glass dish (see Food bowls), which is washed thoroughly with soap and hot water after every meal. Discard any uneaten food and store raw pet food in such a way it does not contaminate human food. After thawing the food, we recommend it is only kept in the refrigerator for 2-3 days.
