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?
