This is what Publix had to say:
Our pet food is produced here in the US by Mars Petcare in TN. The manufacturer informed me that they source their ingredients from the United States using suppliers located near their manufacturing facility when possible. While this is the case for most of their ingredients, some of their vitamins and minerals must be sourced from Asia. To ensure they receive high-quality ingredients, all of their suppliers must comply with their strict and thorough Supplier Quality Assurance program and undergo frequent quality audits. Their products are made with some of the highest quality standards in the industry, and their manufacturing plants perform more than 600 Quality & Food Safety checks daily.
