I've just read this, and you may be right, especially regarding Blue Bell.
If it were an environmental problem, then why are they shutting down all 4 plants? Problem is, if they have started their cleaning regime before carrying out extensive swabbing or hot spotting, they may never find an environmental source!
I'd be going through my ingredients, especially those added after the kill stage, to see if anything is implicated there. I'm sure there are additions that are probably high risk and id be testing these first (via carrying out a risk assessment!). Because there is a CoA with ingredients does not mean that the "portion of the batch" they have is clear. the only way that they can guarantee is to carry out 100% testing! I appreciate that the ripples and flavour they may add are low aW, high sugar, low pH but I suspect not all of them do.
It sounds like it is a common ingredient that may have been contaminated post production but prior to getting to the ice cream manufacturer.
I would run both scenarios (contamination and environment) in tandem. Time is Money!

I agree, it appears that Blue Bell was playing Listeria roulette over the years, and Jeni's caught theirs faster before it spread throughtout their entire factory. And, Jeni's jumped on it faster as well. Interesting... |
