The use of such extracts in addition to having the inhibitory effect of foodborne pathogens is capable of promoting food preservation, thus being a natural food preservative, which has become a consumer preference when compared to synthetic preservatives. In the case of listeriosis outbreaks due to L. monocytogenes, foods such as meat, dairy products, and fresh products contain it in which this bacterium grows even in adverse environmental conditions, such as high salt concentration, low pH and low temperature (Allen et al. 2015; Rothrock et al. 2019; Bahrami et al. 2020).
Fetal Development and Maternal Diet

Pregnancy’s effect on a mother’s immune system decreases its ability to fight foodborne illness. Listeria monocytogenes (foodborne illness) and Toxoplasma gondii (found in cat feces) are two organisms that can pass to an unborn child if the mother is affected. Pregnant women are ten times more likely than the general population to be affected by listeriosis. If infected with Listeria, a pregnant woman may remain asymptomatic or experience only mild flu-like symptoms. However, Listeria has been linked with miscarriage, infants born SGA, and neonatal sepsis. Cooking meats, fish, and poultry until well done to prevent Listeria is recommended. Other sources of Listeria include unpasteurized milk, unheated hot dogs or luncheon meats, imported or unpasteurized soft cheeses, and smoked seafood.

Maternal-neonatal listeriosis is mostly reported during the second and third trimesters of pregnancy, as sporadic cases or in the context of outbreaks.5 Pregnancy-associated listeriosis can lead to devastating consequences to premature and newborn babies.5 Timely diagnosis and treatment should be performed in neonates.5 Early detection of LM-infected cases, particularly in the prenatal stage, remains a major challenge.5 Strains belonging to clonal complexes 1, 4, and 6, classified as hypervirulent clones, are mostly associated with maternal-neonatal listeriosis.5 Maternal-neonatal listeriosis is a direct consequence of LM-specific placental tropism, which is mediated by the conjugated action of two proteins of LM, the Internalins A and B, at the placental barrier.5 Other key virulence factors of LM, such as the actin assembly-inducing protein and the listeriolysin O, are also involved in LM replication in the placental and dissemination into fetal tissues in a non-specific manner, as is Internalin P.5 LM pathogenicity island 4 is also involved in placental and CNS infection by unknown mechanisms.10

Listeria monocytogenes is a facultative intracellular and Gram-positive bacillus that can appear to be Gram-variable on Gram staining (5, 6). Listeriosis occurs mainly through the consumption of contaminated food, and raises public health concerns because of the severity of the disease (meningitis, septicaemia, and maternal-to-neonatal infection) (7, 8). Importantly, listeriosis is an obstetric emergency with increased maternal susceptibility and severe adverse foetal outcomes. Listeriosis is 18 times more common in pregnant women than in the general population and occurs mainly in the third trimester (9). Listeria monocytogenes travels across the placenta to the foetus and causes obstetric complications. Maternal listeriosis tends to be mild and usually presents with non-specific, mild, influenza-like symptoms, whereas foetal listeriosis has a high mortality rate of 27–33%. Neonatal listeriosis is also often severe and can present as sepsis or meningitis, with severe after-effects and a high mortality rate of 20–60% (10). In our case, prompt diagnosis, antimicrobial treatment, and caesarean section to protect the foetus led to favourable outcomes for both the mother and the foetus.

Listeriosis occurs in particular at-risk groups: pregnant women, older people, immunocompromised people, unborn babies, and neonates [2,9,10]. However, the majority of cases are reported to be associated with older adults and not associated with pregnancy [3,4,10]. In healthy people who ingest high numbers of organisms, Listeria monocytogenes infections might cause febrile gastroenteritis, which is usually mild and self-limiting. But in at-risk patients, listeriosis can lead to severe illnesses, including sepsis, meningitis or encephalitis, abortions or stillbirth, and death. The incidence of systemic listeriosis is much higher in susceptible populations, including pregnant women, older people, and immunocompromised individuals [9]. Healthy individuals can also be asymptomatic, fecal excreters of Listeria. Listeria monocytogenes infections often result in admission to intensive-care unit, which places it among the top five foodborne pathogens responsible for the greatest burden in both total costs of illness and loss of QALYs (quality-adjusted life years) [2,10].
