The bags list only where it is distributed and there is nothing on the company web site, but if you can request the information from the DelMonte company.
Sending a request for information to the DelMonte Company brought this response...
"Pup-Peroni, along with the majority of Del Monte Pet Products, are produced at our pet food facilities here in the United States.
It may be helpful for you to know that Federal regulations require a product to list the country of origin if it has been produced outside of the United States or one of its territories. So if one of our products does not specifically state the country of origin, then you can assume it was produced in the United States or a U.S. territory.
