We manufacture high end, RTE imitation crab.
Starting 2 weeks ago, we received a positive listeria result on some product.
We have since had several more positive results on the product
We have followed all protocols, sent additional samples to a 3rd party lab for further testing (negative for L. Mono.)
We have done additional cleaning, more environmental swabbing (40 areas on the line) swabbed our QC lab, etc.
We have a kill step that is closely monitored (88°C)
We've added more boot wash and hand washing stations, changing hand dips more frequently.
EVERYTHING (environmental) we have tested is coming back negative. Yet some product is still testing positive.
We have currently shut down production and are doing a total plant clean up.
I'm currently searching for a 3rd party lab that will come to our facility and do some in-house testing/swabbing.
Does anyone have any ideas on what other steps we can take? Does anyone have a lead on a 3rd party lab within a couple hours of the Seattle area or even BC Canada? (We're between Seattle & BC)
