Raw petfood company Stella & Chewy's has developed a patent-pending SecureByNature system to guard against food contamination throughout the manufacturing plant.

A key component of this system is the hydrostatic high pressure process - a technology that eliminates harmful pathogens without cooking out vital nutrients or changing the natural taste, according to Stella & Chewy's.

To verify the efficacy of the company's food safety techniques, each batch is tested by an independent laboratory for Salmonella and E. coli before packaging.
