I have a question.
I recently changed jobs and this is a new industry for me. I went from RTE poultry production to something completely different and I'm still learning.
My Question is about Tempering-
We receive Frozen 2,000 Lbs totes of Chicken Broth and i wrote a program for thawing in which I included maintaining the product temperature at 40°F during the thawing process and 40-50°F during production. (the final Product will go thru a Kill step/CCP)
I can't find any literature/ supporting documentation for me to use the 50°F temperature in my procedure. I know i had it a couple years ago in one of my other jobs but I can't remember. Can any of you help me with your expertise.
Take a look at Chapter 15 and staph aureus. While chicken broth isn't a 'hydrated batter" perse, it does have a high Aw and falls under the same concept of high Aw, close-to-neutral-pH, and loads of stuff for bacteria to eat. Since it's going through a kill step you primarily need to worry about toxin formation versus bacterial growth. In this instance, the FDA reference does state <50F is unlikely to form a toxin. You likely won't need to be worried about outgrowth of any vegetative pathogens provided your kill step is validated.
I will qualify this whole blooming thing in that I'm in bakery, not meat, so I'm not the right source to say that Staph aureus would be your only concern for sure in that industry as far as outgrowth before a kill step.
