hmmmmmmmmm ... I just checked my jar of Great Value Peanut Butter. It has the 2111 code, but we have not gotten sick, and the jar has been 90% eaten. Would the salmonella not disperse evenly through the batch? Weird.
Someone on another website posted that it was the jars themselves that were contaminated, not the pb, so even if you have an opened jar that you've had no problems with, you should get rid of it.
Dole is recalling canteloupes sold in Quebec & on the east coast, for the same reason - salmonella.
