In 2021, the U.S. Food and Drug Administration (FDA), the Centers for Disease Control and Prevention (CDC), and state and local health and regulatory partners investigated an outbreak of serovar Oranienburg infections linked to bulb onions from Mexico, resulting in 1040 illnesses and 260 hospitalizations across 39 states, the District of Columbia, and Puerto Rico.

- * Affected cows showed signs like decreased milk production, respiratory issues, and altered digestion, with the virus detected in both their milk and tissues.
- * The study highlights the virus's ability to transmit between different species, as it was found to spread from cows to cows and was also detected in other animals, indicating it can cross species barriers.
Article Synopsis
- An unprecedented outbreak of highly pathogenic H5N1 avian influenza (HPAI H5N1) affected bovine herds in the USA in spring 2024, leading to infections in other animals and potential spillover to humans.
- Researchers isolated HPAI H5N1 virus from infected cow milk and studied its impact on mice and ferrets, finding that it spread throughout these animals, including to mammary glands, similar to previous strains.
- Although the bovine H5N1 virus showed some ability to bind to human respiratory tissues and transmit minimally among ferrets, it exhibited features that raise concerns about potential infection and spread in mammals.
The United States are one of the world's leading consumers of melons. In 2020, the Food and Drug Administration (FDA), the Centers for Disease Control and Prevention (CDC), and state health and regulatory partners investigated an outbreak of Newport infections linked to melons from southwest Indiana, resulting in 80 ill persons and 18 hospitalizations reported across 15 states. Epidemiologic and traceback data indicated melons as the vehicle for these infections, but the collinearity of melon varieties purchased and consumed together in combination with the traceback investigation that could not rule out either melon type, did not allow investigators to delineate whether the vehicle was cantaloupe alone or, both cantaloupe and watermelons.
