Outbreak focuses attention on non-O157 E. coliThe recent outbreak of E. coli O145 infection linked to shredded romaine lettuce, which affected at least 26 people in five US states, has prompted a discussion questioning the regulatory focus solely on E. coli O157:H7.
According to a recent New York Times article, the outbreak has caused a reassessment of the situation, with legislators planning to introduce a bill that would make it illegal for many pathogenic strains of E. coli to be present in ground beef. This measure would also require the meat industry to conduct tests for at least six different pathogenic strains. The article states that the USDA has been discussing such a measure for some time, but has faced opposition from industry. American meat producers consider that outbreaks of pathogenic E. coli strains other than O15:H7 have not been associated with beef and that measures to control E. coli O157:H7 will also be effective against other strains.
Although the meat industry tests regularly for E. coli O157:H7, it does not test for other strains. This is partly because rapid tests are not yet available for the six other verocytotoxigenic E. coli (VTEC) strains of concern. Furthermore, little is known about their prevalence in beef, although recent independent testing suggested that 0.7% of retail ground beef samples were contaminated.
