YUMA, Ariz. (AP) - A federal report shows no pathogenic forms of E. coli or salmonella were found in samples of romaine lettuce grown in Yuma, Arizona.
The Yuma Sun reported Thursday that researchers collected 118 samples of romaine lettuce from facilities in the Yuma area in December.
The Food and Drug Administration report says that tests did detect one strain of E. coli but the form is not one harmful to humans.
The agency says the samples were collected at random intervals as crops arrived to cooling facilities.
The tests followed an E. coli outbreak linked to romaine lettuce in spring 2018.
The Centers for Disease Control and Prevention recorded about 200 people sickened and five deaths from the outbreak traced to Yuma.
