Salmonella , E-coli and others - for people who are biologists or professionals

[nirge888]

Hello,

1.Do you know if Salmonella, E-coli and others can survive in freezing temprature of -18C ?

 

2.Can they survive in dogs stomach acid in PH level of 1?

 

Thanks!

1) Depends on the method of freezing and the number of bacteria, but mostly yes. Repeated freeze thawing can kill some off, but many will survive.

 

2) I think the pH in the stomach is on average above 1 but again, it depends on how many are sent through. There are pH resistant strains, but even sensitive ones might survive the passage, only with a much lower yield.
