| e. coli o157:h7 is an emerging pathogen in missouri. | dramatic media reports of recent outbreaks of illness caused by escherichia coli o157:h7 have drawn national attention to this emerging pathogen. in 1993, a widely publicized outbreak of over 500 culture-confirmed cases was traced to fast-food hamburgers in washington, idaho, nevada and california. closer to home, the first (and still the largest) reported waterborne outbreak of this disease occurred in cabool, missouri in 1989. that outbreak affected 243 people, of whom 32 were hospitalized, 2 ... | 1994 | 7854310 |

| a multistate outbreak of escherichia coli o157:h7 infections linked to alfalfa sprouts grown from contaminated seeds. | a multistate outbreak of escherichia coli o157:h7 infections occurred in the united states in june and july 1997. two concurrent outbreaks were investigated through independent case-control studies in michigan and virginia and by subtyping isolates with pulsed-field gel electrophoresis (pfge). isolates from 85 persons were indistinguishable by pfge. alfalfa sprouts were the only exposure associated with e. coli o157:h7 infection in both michigan and virginia. seeds used for sprouting were traced ... | 2001 | 11747724 |
| feedstuffs as a vehicle of cattle exposure to escherichia coli o157:h7 and salmonella enterica. | feed has been reported as a vehicle for transmission of salmonella enterica in cattle and several lines of evidence suggest that feed can be a vehicle for transmitting escherichia coli o157:h7 as well. to show whether microbial contamination of feeds could contribute to the populations of s. enterica and e. coli o157:h7 on a farm, we compared isolates from feed samples to bovine fecal isolates from the same farm using pulsed-field gel electrophoresis (pfge). four of 2365 component feed samples ( ... | 2003 | 12935747 |
| outbreak of shiga-toxigenic escherichia coli o157:h7 infections associated with rodeo attendance, utah and idaho, 2009. | abstract objectives: in summer 2009, the utah department of health investigated an outbreak of shiga-toxigenic escherichia coli (stec) o157:h7 (o157) illness associated with attendance at multiple rodeos. materials and methods: patients were interviewed regarding exposures during the week before illness onset. a ground beef traceback investigation was performed. ground beef samples from patient homes and a grocery store were tested for stec o157. rodeo managers were interviewed regarding food ve ... | 2011 | 21657937 |
