Federal and state health officials are investigating a multistate Salmonella outbreak connected with a potentially contaminated organic packaged coconut that was sold at Natural Grocers stores, a product that was the subject of a recall posted by the US Food and Drug Administration (FDA) yesterday.

In the recall notice, Vitamin Cottage Natural Food Market, Inc., based in Lakewood, Colo., said it was recalling its Natural Grocers brand 10-ounce Coconut Smiles Organic due to potential Salmonella contamination. It said six illnesses have been reported, the company’s own routine tests found Salmonella in some packages, and a sample taken by the FDA was also positive for Salmonella.

The product is packaged in clear plastic 10-ounce bags bearing the Natural Grocers label. All packages with packed-on dates before 18-075 (Mar 16, 2018) are subject to the recall. The products were distributed to 145 Natural Grocers stores in 19 states: Arkansas, Arizona, Colorado, Iowa, Idaho, Kansas, Minnesota, Missouri, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oklahoma, Oregon, Texas, Utah, Washington, and Wyoming.
