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.

Salmonella, is an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Healthy persons infected with Salmonella often experience fever, diarrhea (which may be bloody), nausea, vomiting and abdominal pain. In rare circumstances, infection with Salmonella can result in the organism getting into the bloodstream and producing more severe illnesses such as arterial infections (i.e., infected aneurysms), endocarditis and arthritis.
Listeria monocytogenes, is an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, Listeria infection can cause miscarriages and stillbirths among pregnant women.
Enterohemorrhagic E. coli is a bacteria that causes a diarrheal illness often with bloody stools. Although most healthy adults can recover completely within a week, some people can develop a form of kidney failure called Hemolytic Uremic Syndrome (HUS). HUS is most likely to occur in young children and the elderly. The condition can lead to serious kidney damage and even death.
