In the study, researchers analyzed the entire genome of over 1,600 Listeria strains. These DNA profiles were used to train a machine learning model that learned to identify genetic patterns associated with resistance to disinfectants commonly used in the food industry. 

According to FDA, between 2018 and 2025, 42 people were sickened and 14 died across 21 states after consuming Listeria monocytogenes-contaminated Sysco Imperial and Lyons ReadyCare Frozen Supplemental Shakes that were served at long-term care facilities and hospitals. 

In 2024, UKHSA investigated seven listeriosis outbreaks across England and Wales, linked to various food products including smoked fish, chocolate and strawberry mousse, garlic sausage and pre-packed sandwiches.

As part of its ongoing public awareness initiatives, the Saudi Food and Drug Authority has released information detailing common types of food poisoning linked to fish consumption and crucial preventive measures to protect public health.

Consumer purchase records were successfully used for hypothesis generation in the outbreak investigation and provided a critical foundation for traceback activities.

Initially launched in 2024, the investigation was reopened in April 2025. Whole genome sequencing (WGS) analysis confirmed that the strain of Listeria found at Fresh & Ready Foods LLC matches the strain of Listeria causing illnesses in this outbreak.

The 2023 annual report highlights a few noteworthy outbreaks: illnesses linked to toxins from morel mushrooms, lead linked to cinnamon in applesauce pouches, and Listeria monocytogenes linked to soft serve ice cream cups.

Collaboration between the two agencies suggests that the suspected source of the outbreak involves products under the jurisdiction of both.

A recent study showed the high prevalence of Campylobacter in Nigeria with poultry as the primary reservoir, carrying significant food safety implications, and highlighting the importance of controlling the pathogen from a One Health perspective.

A study has validated and verified two gas-phase hydroxyl radical processes for inactivating Salmonella and several avian pathogens on poultry hatchery eggs without affecting the egg hatch rate or development of hatched chicks, providing a viable alternative to traditionally used, hazardous and toxic formaldehyde treatments.
