Hydrostatic High Pressure (HPP) is a technology that uses pressurized water to pasteurize food. Essentially, the process squeezes out the food’s harmful bacteria, like Salmonella, without changing the food’s taste. HPP is an especially important process for raw dog food and treats because it maintains all of the food’s nutrients. Which is why we’re feeding them raw food in the first place, right?

HPP is an especially important process for raw dog food and treats because it maintains all of the food’s nutrients. Which is why we’re feeding them raw food in the first place, right?
How it Works
HPP was founded in the discovery that bacteria cannot survive at pressures five times those found at the deepest sea level. The process takes only 3 minutes to pasteurize food. During the HPP process, a vessel with the food inside of it is filled with water and brought to a peak water pressure of 87,000 pounds per square inch (psi). The water and food are kept at a relatively low temperatures throughout the process to avoid cooking the food. Afterwards, the food is generally frozen for later processing.
The Benefits
HPP is the only scientifically recognized pasteurization process that doesn’t use heat or irradiation. So, it’s really the only pasteurization process available for raw pet food and treats at this time. It’s an especially important process for senior dogs and dogs with compromised immune systems, who are more susceptible to bacteria that may be present in un-pasteurized raw dog foods. So, while “Hydrostatic High Pressure” may sound complicated, rest assured that the process is just another step that raw dog food producers are taking to keep your pup healthy and happy.
