HIGH APC in RTE ice cream desserts.

We continue to get high APC counts above 50,000 cfu/g in our finished product ice cream desserts. There is no kill step. Mix that we use already comes in pasteurized. We have done extensive ATP swabbing of zone 1, mix samples and they all come back clean. What can be the issue?

Perform APC swabbing of Zone 1.

Take APC samples of the mix.  What's the spec say for APC?  Pasteurized doesn't mean sterile.
Have you looked at your packaging materials?  Both as they come in as they're first opened, and after they've been opened - how are they handled/stored?

Also do APC air monitoring if you haven't already. 

Do you add anything to the mix at all?

Hello Marshenko, 

 

We have performed APC of Zone 1 and they come back clean. We have also collected samples of mix and they also come back clean. We have also done ATP swabbing of all packaging material and have also come back clean. 

Also do APC air monitoring if you haven't already.

Hello kconf, 

 

We have done APC on the air, and it come back within range. We add vanilla flavor to the mix, which we have also sent in for testing and comes back clean.
