The current study explored the health risk of E. coli O157:H7 to diarrhoeic confrimed and non-confirmed HIV/AIDS patients due to their exposure to presumed ingestion of water, meat, meat products and vegetables ostensibly contaminated with E. coli O157:H7. Strains of E. coli O157:H7 were isolated by enrichment culture and on Cefixime-Telurite Sorbitol MacConkey agar. Average counts of presumptive E. coli O157 were used for dose-response assessment.Probability of infection to confrimed and non-confirmedHIV/AIDS patients was 20 and 27 % from meat and meat products, 21% and 15% from vegetables and 100% due to ingestion of 1500ml person day of water. Drinking water had higher probability of transmitting E. coli O157 :H infections than meat and meat products and vegetables.Prabability of E coli O157:H7 infections were high for confrimed HIV/AIDS patients than for non-confirmed patients. Water and foods consumed by HIV/AIDS patients should be safe of any microbial contaminants, these waters and foods should as well be investigated for other enteric pathogens to establish their safety.
