Wisconsin officials are recommending residents throw away bags of spinach distributed by a Milwaukee food processor after some tested positive for salmonella.
The Wisconsin Department of Agriculture, Trade and Consumer Protection says consumers should discard 10-ounce bags of Kleen-Pak curly-leaf fresh spinach with use-by dates of April 29, April 30 and May 1.
It says routine food safety tests of the spinach were positive for salmonella.
The bacteria can cause diarrhea, fever and vomiting. Infections can be deadly to young children, the elderly and those with weakened immune systems.
Kleen-Pak spinach is distributed in grocery stories in Wisconsin and Illinois.
