The Sprouts Farmers Market grocery chain is recalling conventional and organic frozen spinach manufactured by National Frozen Foods of Oregon, because a random test came back positive for Listeria monocytogenes.

The test showed the bacteria in the finished product, according to the company recall notice posted by the Food and Drug Administration. However, the notice from the Phoenix-based retailer did not say whether the testing was conducted by the FDA, Sprouts or the spinach manufacturer.

Consumers are urged to check their homes for the recalled Sprouts brand frozen spinach. No one should eat the recalled spinach and anything used to store or prepare it should be throughly washed.

To determine whether they have the recalled spinach in their homes, consumers should look for the following label information:
