Outbreak of Non‐O157 Shiga Toxin–Producing<i>Escherichia coli</i>Infection from Consumption of Beef Sausage

Abstract

We describe an outbreak of Shiga toxin-producing Escherichia coli O26:H11 infection in 20 patients (median age, 2 years). The source of the infection was an organic fermented beef sausage. The source was discovered by using credit card information to obtain and compare customer transaction records from the computer systems of supermarkets.
