It doesn't say. They are made by Del Monte Foods since 1908 and I have been giving the hard version to my dogs for many, many years. My chihuahua can't eat the hard ones, but he loves these soft ones. I feel pretty safe feeding them and they are the only ones that have a little nutritional value.
It shows in large letters on the front label that it is made in NY, USA. Look in the lower left corner of the front label. I wanted to know that too, so it was hard to find, since it's usually buried in tiny font on the back label.
