And the biochemical test for salmonella please.

Answer 1

hi, if you look at my answer on lactobacilli and sourdough you will have your answer. You need to swab the food and lawn it on agar. When the lawn has grow up you need to isolate the colonies on another agar plate.Probably better than lawning a plate is to swab the specimen and grow the sample in nutrient broth and the isolate the colonies on agar.MacConkey agar is good for Salmonella colonies which are not well isolated From there you can perform the biochemical tests which I mentioned in my previous answer. However you do need to know what you're looking for with Salmonella.

I wish I could go on some more, but I just checked the time and I'm running late for a bus! So look at this site:

and it will give you loads of info

Answer 2

You need petri dishes and a lab to do this. Take it on faith that no raw food is sterile. Fortunately, your immune system does a pretty good job handling the bacteria on food. As far as salmonella goes, wash your meat, cook it thoroughly, and wash your hands and all surfaces you used to prepare the meat. This should protect you very well.
