I believe what your talking about is something like this:
Wash hands, put on gloves, sanitize sampling port, open sanitary container, fill container, close container, return to lab?
We had a procedure for pulling yogurt samples like that. Sanitizing the sampling port was something like sanitizer in a bag and you pushed on the bottom of the bag to have sanitizer rise up, cover the port, and fall back down. I believe we did that like 3 times. We did let some of the product fall out of the sampling port onto the floor before putting it into the container... but yogurt on the floor was nothing out of the ordinary in a days work.
