Let’s be frank, grass fed beef is not pathogenic E. coli free despite all the marketing bullshit. Please take a long look at my Op-ed of a few years ago.
FSIS was notified of an investigation of E. coli O157:H7 illnesses on June 25, 2014. Working in conjunction with the Massachusetts Department of Public Health and the Centers for Disease Control and Prevention (CDC), FSIS determined that there is a link between ground beef purchased at Whole Foods Market and this illness cluster.
Based on epidemiologic investigation, 3 case-patients (including one HUS caused death) have been identified in Massachusetts with illness onset dates ranging from June 13, 2014 to June 25, 2014. While the onset of illnesses was in June, on August 13, 2014, additional laboratory results provided linkages between the 3 MA case-patients and ground beef purchased from Whole Foods. Traceback investigation indicated that all 3 case-patients consumed ground beef purchased from 2 Whole Foods Market prior to illness onset.
The meat – yes, grass fed, that went into the ground beef, came from Rain Crow Ranch.
