Recurring Listeria outbreaks in the United States is a growing public healthcare concern. Although no associated reported death, 17 were hospitalized out of the 18 reported illnesses in the recent outbreak in 15 US states. The United States has experienced about 30 Listeria outbreaks in the last decade with 524 Listeriosis cases and 80 deaths. The identified origin were ice cream, leafy greens, mushroom, meat slice, dairy products like cheese, packaged salads, cooked chicken, hard‐boiled egg, pork product, frozen vegetable, raw milk, packaged caramel apple, bean sprout and soya products. Although rare, Listeria may lead to serious illness (invasive listeriosis) or death. Listeriosis is critically harmful and medically complicated, especially in the pregnant, the old above 65 years and in the immunocompromised. It could cause premature birth, miscarriage or even neonatal death. Hospitalization is often necessary in the geriatric, being fatal at times. Among Listeria sp., Listeria monocytogenes is often human infection‐associated. It is a gram‐positive, non‐sporulating, motile bacillus opportunistic pathogen. Food‐borne listeriosis is often associated with frozen foods due to its ability to thrive at low temperatures. Hypervirulent strains of L. monocytogenes with an ability to infect the respiratory system (the lungs) was recently reported in the coronavirus disease‐19 patients during the pandemic. L. monocytogenes seemed to have developed antimicrobial resistance to ciprofloxacin and meropenem, possibly acquired through the food chain. An early onset of listeriosis in the newborn is evident in the first 7 days postparturition. As the bacteria colonize the genitourinary tract, majority of such cases result from teratogenic transfer during vaginal delivery. Premature newborns, neonates born outside healthcare facilities and low‐birth‐weight babies were increasingly predisposed to an early onset of listeriosis. Listeria outbreaks were earlier reported in South Africa, Australia and Europe, with an unclear origin of the outbreaks. Social media updates about such outbreaks, the most likely food source, and measures to self‐protect are suggested as preventive measures. The article deals on various such aspects related to listeriosis primarily originating from food, to ensure better public healthcare and human wellness.

Listeriosis is a saprozoonotic infection caused in humans mainly by the species Listeria monocytogenes. Its source can be objects of the external environment (soil and water of open reservoirs with a high content of organic compounds, plants) and more than 90 species of animals. The high metabolic activity of listeria and resistance to adverse factors create the possibility of an easy transition from a saprophytic to a parasitic type of metabolism when ingested by the host. A variety of transmission routes and "entrance gates" cause the emergence of a variety of primary localized forms of infection, the most common of which is gastrointestinal. Invasive forms of listeriosis develop mainly in people with immunological insufficiency. "Risk groups" are pregnant women, newborns, people with comorbid conditions, over 60 years old, drug addicts, etc. They are characterized by polymorphism of symptoms, the absence of specific manifestations. Pathogenicity factors of L. are important in the pathogenesis of infection. monocytogenes, providing their incomplete phagocytosis, intracellular parasitism, high rate of colonization of neighboring healthy cells, the formation of antibiotic resistance. The pathological expression of changes caused by listeria in cells is the formation of small granulomas — listeriomas. The "diversity" of listeriosis, the high mortality rate (up to 50% or more) and the low alertness of doctors regarding this infection create difficulties in making a diagnosis, and therefore the improvement of microbiological diagnostic methods is of particular importance.
