The value of a latex agglutination test (Escherichia coli O157 latex test; Oxoid Ltd.) for rapid presumptive detection of E. coli serotype O157:H7 was determined by laboratory trials and during an outbreak of hemorrhagic colitis. The latex test was found to be a simple, highly efficient and reliable test in detecting E. coli O157:H7 with 100% sensitivity and specificity. It was also found that sorbitol-MacConkey agar cultures were not as useful for food samples as they were for fecal specimens in screening for E. coli O157:H7, but the use of the latex screen was particularly efficient in this setting.
