Nutro would not reveal zinc levels in their food so Pet Food Products Safety Alliance (PFPSA) tested the food and found that zinc levels were 2100 ppm! As Dr. Hansen told Consumer Affairs, that's "sky high".

Dr. Hansen:
Tests Find 'Sky High' Zinc Levels in NUTRO Cat Food
At PFPSA's site you will see that dog food was tested in 2008. High zinc levels were found, but findings were ignored by Nutro and FDA.
The problem with Nutro has been going on for YEARS! There are over 900 complaints on Consumer Afairs website.
