A total of 32 people in four states are reported to have been infected by the outbreak strain of E. coli O157:H7 since 13 October. About 32% of those affected have required hospital treatment and two have developed haemolytic uraemic syndrome (HUS). This particular strain of toxigenic E. coli has not been previously reported in the USA.

Epidemiological evidence suggests a link with Field Fresh Chopped Salad with Chicken and Mexicali Salad with Chili Lime Chicken. On 10 November, Glass Onion Catering voluntarily recalled these and a number of other products that could potentially be contaminated with E. coli O157:H7.

The outbreak investigation is on going and more information can be found here.
