Abstract: Globally, foodborne diseases are estimated to cause over 600 million illnesses and 420,000 deaths each year. Listeriosis is a major foodborne bacterial zoonotic disease that is reported many countries of the world. The disease is caused by the ingestion of Listeria contaminated foods. Almost all infections in humans are caused by Listeria monocytogenes and sometimes Listeria ivanovii may be implicated in the disease. Elderly persons, infants, pregnant women, and immunocompromised individuals are highly susceptible to infection. The bacterium has ability to multiply at refrigeration temperatures. Cross contamination can occur in food industries. Various types of foods including the raw milk, butter, soft cheese, ice cream, meat and others are implicated in the outbreaks of foodborne listeriosis. Listeria monocytogenes has zoonotic potential due to their ability of transmission from animals to humans. Disease is categorized into two forms, namely severe invasive listeriosis and non-invasive febrile gastroenteritis. The organism contains important virulence factors. The definitive diagnosis of listeriosis was based on the isolation and identification of the bacteria in samples. The drug sensitivity pattern of bacteria poses major public health problems since antibiotics have been used since long time. The poor laboratory facilities pose a challenge in early diagnosis in developing countries. The best preventive strategy is to avoid the consumption of contaminated raw foods, especially of animal origin.
