Apples Recalled Due to Positive Screen for One of Three Pathogens

A MN firm is recalling apples because a test indicates the presence of Listeria or Salmonella or E.coli.  So basically, they don't know which because who ever did the test ran a screen which looks for indicator genes for each of the three.

The recall was probably based upon a positive reaction of the test without the isolation of the actually pathogenic organism.  This is the problem with a screen - not sure which organism or it is just a false positive result.
