Sorry I keep posting here, but I have more information from Diamond as to which bags of food might contain the preservative:
"Product with the "best before" date of January 2007 through March 15, 2007
could contain very low residual levels of ethoxyquin from the ocean fish
meal. This food is safe to be fed to your pets. "Best before" dates prior to
January 2007 or after March 15, 2007 will either not contain ocean fish
meal or will contain naturally preserved ocean fish meal, respectively." |
