Nutro  has reintroduced its dry cat food after the voluntary recall in May, according to a news  report .

The company said its food-safety program now has stricter quality checks for suppliers and extensive testing of inbound raw materials and finished products. It has also reportedly enhanced the ingredient quality.

In May, the company discovered that two premixes from one of its US-based suppliers contained excessive levels of potassium and zinc.

Nutro announced August 7 that all its cat food brands were available at petfood retailers.
