Primal adheres to a science-forward approach, always striving for the most optimal safety and quality measures. High-Pressure Processing (HPP) is a unique process that kills pathogenic bacteria through high-pressure, water-based technology. High-Pressure Processing is a USDA-approved, 100% natural process, and is allowed for use on organic and natural products.
We have studied HPP since 2008 and have a thorough understanding of its benefits. We have performed enzyme testing on both non-HPP and HPP raw pet foods and the findings show that there is virtually no change in the nutritional integrity of the product if the process is performed accurately and with the correct scientific and production knowledge.
