The federal government is going to require growers of leafy greens in the Central Coast Growing Region of California to pre-test for food-poisoning bacteria before they begin harvesting.
It comes after repeated problems every fall since 2017 with E.coli 0157:H7.
One year investigations identified the exact same strain that was causing the food poisoning and massive recalls in a drainage ditch about a mile from the fields growing leafy greens.
That ditch contamination was cattle manure.
