What is the incubation period for listeriosis?

Listeriosis has a long and variable incubation period. After consuming contaminated food, illness can take a wide range of time to appear because Listeria can grow slowly in the body and factors like the person's immune status or pregnancy can influence onset. The typical window is about 3 to 70 days, but it can extend up to around 90 days in some cases. Therefore, the choice that lists 1-90 days with the usual 3-70 days best reflects the real-world variability of incubation for listeriosis. Shorter time frames like a day, a few days, or two weeks don’t capture howLate the disease can be before symptoms show up.
