Can E. Coli o157:H7 or Salmonella survive after dessication?

Question

I wan to know if E. Coli o157:H7 or Salmonella can survive on a dry surface.

Answer 1

sure can, alot of bacteria will form endospores with hard membranes that will enable them to last through periods that are not conducive to growth like a dry counter top. chances are bacteria are still there waiting for an opportunity to start reproducing. So simply drying out a cutting board will not sanitize it, you need chemicals, heat or UV to do this.  

Answer 2

Yes. E. coli and Salmonella do not form spores, but they do not die easily. They can survive on a dry surface for some time, especially when the surface is dirty or the humidity of the air is high.
