Is frost buildup in walk in freezers a food safety risk?
I just wanted to give a huge thank you to everyone who contributes to this forum. I finished my food science degree a year ago, started my job right after, and got to work learning about SQF and building a Food Safety program with the goal of SQF level 2 certification. After having our certification audit last week, we passed with no majors and just a few minors! Thank you all so much for taking the time to help people like myself wade through codes and help to improve our companies processes and procedures.
Also, a quick question! The auditor got me for some frost buildup in a couple of walk in freezers. Product stored inside these freezers is frozen cookie dough packaged in sealed poly film and then inside taped shut cardboard boxes. I have no problem taking steps to get rid of the frost, but was curious as to what the problem is with there being some frost buildup in a case like this, when I don't believe there is any food safety risk.
Auditors don't like to see frost build up----it's a sign of other PM issues
The risk is, your inside liner could be compromised---frost builds up on the carton, they could thaw and contaminate the product
Same here, all product is covered in freezer but still no frost allowed

Hi Timbeau,
Do you mean a freezer or a frozen cold storage room ? Hopefully not one and the same thing.
I assume you mean a (nominal) <= -18degC freezer.
Assuming you mean significant frost build-up, the implication is that meaningful temperature swings are occurring and/or unusually high humidity is present.
So what is the reason ? Inadequate screening at the entrance ? Overloaded with product ? air leakage ? Hot product directly inputted ?
How about the temperature records ?
