One of the many benefits of Simply Raw is that our food is freeze-dried raw, making it the safest and most effective way to feed your dog a raw diet. Freeze-drying is a high pressure food preservation method that removes water and pathogens at extremely low temperatures without cooking food. The freeze-drying process is so effective at removing pathogens from food that this is the preferred method of food preservation used in the long term food storage industry, including disaster preparedness food designed to last on the shelf for up to 25 years. Due to its high level of safety, freeze-dried raw dog food has one of the lowest recall rates of all dog food categories.
