from hospitals were contaminated with Salmonella. This contamination was more severe during the summer. The Salmonella replicated in moist food but survived longer in the cockroaches. Kirby and Davies [24] showed that Salmonella replicated rapidly in mixed foods and on surfaces that have been washed but were not adequately sanitized. These survival times are very long if the organism is not exposed to sunlight. It was shown that Salmonella oranienburg in feces of P. americana for more than 3.25 years on cornflakes, 4.25 years and on crackers, 3.67 years is stable. These feces can contaminate mice and poultry [25]. In this work, it was shown that some of the isolated Salmonella were resistant to antibiotics and Salmonella contaminated almost 71% of B.
