Using 1,204 samples collected during 2016–2023, the researchers observed statistically significant reductions in the median time from sample collection to the issuance of a national genomic surveillance report to 26 days, despite sample numbers doubling in 2022 and 2023.

For those foodborne illnesses where a specific food item was identified, vegetables represented the single largest food category in terms of reported illness cases, followed by composite meals, seafood, and buffet food.

In the face of the alarming rise and spread of antibiotic-resistant bacteria, researchers set out to find and develop non-antibiotic biological disease control and prevention options for aquaculture.

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.
