Eating contaminated food with high numbers of L. monocytogenes is the main route of infection. Where active surveillance of sepsis and meningitis has been carried out, attack rates of listeriosis are ∼0.7 case per 100,000 population [22]. Furthermore, the success of such passive surveillance system largely depends on 1971 Mar;123(3):247-50. In pregnant women it may cause stillbirth or spontaneous abortion, and preterm birth is common.

Educating consumers, especially those in high risk groups, and training of food handlers in safe food handling are among the most critical means to prevent foodborne illnesses including listeriosis. Since then, Chinese medical journals have published hundreds of reports of listeriosis. Although human listeriosis is rare (upper estimate of 12 cases per million population per yr), mortality can reach 50%. However, in rare situations, outbreaks of listeriosis occur in humans. The control of L. monocytogenes is required at all stages in the food chain and an integrated approach is needed to prevent the multiplication of this bacteria in the final food product.
