Food Safety News: Company officials knew a Dole salad plant was contaminated with Listeria for a year and a half before they shut it down — then they only took action after the U.S. and Canadian governments traced a deadly outbreak to the facility. Inspection reports (483) obtained by Food Safety News revealed the timeline of positive Listeria results and inaction. Dole Fresh Vegetables Inc. finally suspended production at its salad plant in Springfield, OH, on Jan. 21 this year after a random test by state officials showed a bagged salad contained Listeria monocytogenes.
By that time, at least 33 people in the U.S. and Canada had been sickened with the same strain of Listeria as was found when Ohio inspectors tested the Dole salad they collected from a retailer. All 33 victims had such severe symptoms they required hospitalization. Four of them died.
