For symptomatic patients, diagnosis is confirmed only after isolation of Listeria monocytogenes from a normally sterile site, such as blood, spinal fluid, or amniotic fluid or placenta. Stool samples are of limited use and are not recommended.  Can be isolated readily on routine media, but care must be taken to distinguish this organism from other Gram-positive rods, particularly diphtheroids. Selective enrichment media improve rates of isolation from contaminated specimens. You can expect that that the cultures will take one to two days for growth. Importantly, a negative culture does not rule out infection in the presence of strong clinical suspicion. Serological tests are unreliable, and not recommended at the present time.

People get listeria by eating food contaminated with Listeria monocytogenes. Babies can be born with listeria if their mothers eat contaminated food during pregnancy. However, healthy people may consume contaminated foods without becoming ill. People at risk can prevent listeria by avoiding certain higher-risk foods and by handling and storing food properly.

However, in some ready-to-eat meats, such as hot dogs and deli meats, contamination may occur after factory cooking but before packaging or even at the deli counter. Also, be aware that Mexican-style cheeses made from pasteurized milk and likely contaminated during cheese-making have caused infections.

Pregnant women may experience a fever and other non-specific symptoms, such as fatigue and aches, followed by fetal loss and meningitis in their newborns.
