Earth Options by Pets1st recipes undergo stringent testing for both quality and safety. They are manufactured at plants which are EU, FDA, and CFIA certified. This means that they must meet a very high standard of sanitation, cleanliness and manufacturing practices. There are specific independent audits performed regularly by well-respected human-food audit companies. We test our ingredients before receiving them at the plant, for a variety of toxins as well as for their nutrient density and proper moisture levels. We then continue testing for salmonella and e-coli during all levels of the manufacturing process, using the standards set by Health Canada. We use state of the art technology to accurately measure protein, fat and moisture levels in our recipes. We record batch numbers so they can be traced back immediately. Finally, we package our product in a bag that provides ultimate protection against rancidity as we use only natural preservatives. This bag contains a plastic layer which is fused to a foil layer. Currently this type of bag is not part of any commercial recycling program. This is why as part of our environmental sustainability commitment, we offer a recycle program that helps keep these bags out of landfills.
