Apparently a high percentage of household roaches carry salmonella also. Plus.. who the heck thought to test DEAD RATS for salmonella? I mean.. really?
I'm one that's not so picky about everything being sterile and super clean, but I rarely EVER get sick, never have had(knock on wood) any food borne illness or salmonella. I have a hyper-immune system though. When I work a kitchen, work on food while camping with others, or prepare food that others will consume, I am ANAL about everything being clean and sanitary. It's the basics for food prep to have things clean, and not cross-contaminate items.
I just got chicks from Mice Direct at the local Repticon in Kissimee. Since chicken is often a carrying factor for salmonella, think that could be the cross-contamination origin?
