New vaccine technology decreases E. coli in beef cattle

Despite millions of dollars spent on food safety research over the last 10 years, ground beef recalls due to E. coli O157:H7 were higher in 2007 than in 2006, according to researchers from Kansas State University and West Texas A&M University. E. coli O157:H7 has been linked to foodborne illnesses in humans after consuming contaminated beef and produce.
