The recall began when the Tennessee Department of Agriculture sampled one of brands where the source was from Deutsch Kase Haus, but went through a middleman packaging operation, MDS Food manufacturing facility in Tennessee. It will be interesting to see if this contamination originated at teh MDS facility. At the least, this MDS facility would need to worry about the fact that cross contamination could be an issue in that facility. And while they recalled the Colby cheese product produced on the same line, to what degree do they need to worry about other cheese packed in that facility.
In general, the more post-process handling and processing that occurs,such as wtih slicing and packaging, the more opportunity there is for Listeria contamination.
