Multistate Outbreak of Listeria monocytogenes Infections Linked to Fresh, Soft Hispanic-Style Cheese — United States, 2021

The Microbiology of Cheese and Dairy Products is a Critical Step in Ensuring Health, Quality and Typicity

“…[75] and Clostridium botulinum [76] were detected in dairy products, highlighting the sensitivity of these food products to possible contamination by dangerous microorganisms. In Table 2, examples of pathogenic bacteria contaminating dairy products have been reported [77][78][79][80][81][82][83]. L. monocytogenes can be life-threatening, with outbreaks associated with high mortality rates, typically 20-30% [84].…”

A scalable route to quaternary ammonium-functionalized AgCl colloidal antimicrobials inhibiting food pathogenic bacteria and biofilms

“…Listeria monocytogenes is one of the most dangerous Gram-positive pathogenic bacteria for human health, causing listeriosis by consuming contaminated food [ 12 ]. A foodborne disease outbreak still present nowadays, with a high mortality rate, indicates an urgent warning emphasizing the risk of contaminated products [ 13 ]. Staphylococcus aureus is one of the most common food-poisoning microorganisms isolated from fresh and processed food [ 14 , 15 ] .…”

Quercetin mediated antimicrobial photodynamic treatment using blue light on Escherichia coli O157:H7 and Listeria monocytogenes

“…However, foodborne outbreak related with liquid food such as milk and fruit juice has constantly reported,causing the hospitalization and death of people every year ( Mostafidi et al, 2020 ; Sebastianski et al, 2022 ). Among these outbreak, Escherichia coli O157:H7 and Listeria monocytogenes, were strongly associated with milk and fruit juice contamination, and recently 12 patients and one died due to L. monocytogenes in cheese made by pasteurized milk in 2021 ( Palacios et al, 2022 ; Treacy et al, 2019 ). It is well-known that E. coli O157:H7 can produce Shiga-like toxins that cause hemorrhagic colitis and hemolytic uremic syndrome ( Kolodziejek et al, 2022 ), and L. monocytogenes produces listeriolysin O to escape host macrophages and caused listeriosis, which was especially fatal to expectant mothers ( Pal et al, 2022 ).Therefore, it is of great importance to inactivate these pathogens in liquid food, especially in milk and fruit juice.…”
