jla, Hi there. Of course your concerned about
your lower resistance while on Humira.
Salmonella is a gram-negative bacteria that pass from the feces of people or animals to other people or other animals.
Wash your hands with warm soapy water for 20 seconds before and after handling food and after using the bathroom, changing diapers, and handling pets. You should be okay if you always remember to wash your hands appropriately. I have not addressed the salmonella that is spread through food not being prepared properly.
Take care and keep posting.
