The state is allowing a Fresno County dairy to resume producing raw milk products after a three-week investigation into four cases of E. coli poisoning in Southern California.

"The recall and quarantine were lifted because Organic Pastures dairy met the requirements of the state to resume manufacturing operations," Steve Lyle, spokesman for the California Department of Food and Agriculture, told the Sacramento Bee.

McAfee, the state’s largest organic raw milk producer, was at the center of an inquiry by the California Department of Food and Agriculture and the Department of Health Services after four children became ill with E. coli poisoning.
