Federal regulations permit the applicant/employee to request the split specimen that was collected at the time of the original specimen be sent to another laboratory for testing. This request should be made to the MRO within 72 hours of the employee being notified of the positive test result.
Shiga toxin-producing E. coli(STEC), also called verotoxinogenic E. coli, usually do not cause disease inanimals but may cause watery diarrhoea, haemorrhagic colitis, and/orhaemolytic uraemic syndrome in humans. Zoonotic STEC include the O157:H7strains and, with increasing frequency, certain non-O157 strains.
E. coli O157:H7 and other enterohemorrhagic E. coli (EHEC) typically cause acute bloody diarrhea, which may lead to hemolytic-uremic syndrome. Symptoms are abdominal cramps and diarrhea that may be grossly bloody. Fever is not prominent. Diagnosis is by stool culture and toxin assay.
