USDA has announced the availability of financial investments to combat the ongoing highly pathogenic avian influenza H5N1 outbreak, including $500 million for farm biosecurity and $100 million for the development of chicken vaccines and other therapeutics.
Field studies led by Wageningen University have demonstrated the efficacy of two vaccines in reducing mortality in poultry infected with the Highly Pathogenic Avian Influenza (HPAI) H5N1 virus, although it is too early to draw accurate conclusions about transmission.
A rodent study using real-world non-typhoidal Salmonella strains, conducted by University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers, has shown the potential of a developing vaccine that is based in a novel, nontraditional delivery method.
An Oxford University researcher was awarded £5 million to develop a Campylobacter vaccine for livestock, which will be made possible by data gathered through a global metagenomic surveillance network that is established through collaboration with 19 partner countries.
In support of its proposed regulatoryframework for Salmonella in raw poultry, USDA-FSIS has notified veterinary biologics manufacturers of its interest in vaccines for serotypes of public health significance.
A recent study suggests that global control measures for Highly Pathogenic Avian Influenza (HPAI) H5N1 infection in poultry and dairy cattle are insufficient. Gaps in control measures exist, including resistance to modern vaccines and surveillance technologies.
At the 2024 Farm Progress Show, U.S. Department of Agriculture (USDA) Secretary Tom Vilsack revealed that the agency is beginning field trials for a vaccine to address the ongoing outbreak of Highly Pathogenic Avian Influenza (HPAI) H5N1—also known as “bird flu”—in cattle.
To encourage the use of Salmonella vaccines for poultry flocks, the U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS) intends to exclude current commercial vaccine subtypes of Salmonella confirmed in FSIS raw poultry samples from the calculation used to categorize establishments under the raw poultry Salmonella performance standards.
Researchers from the Washington University School of Medicine in St. Louis are developing a vaccine for human norovirus, which is the leading cause of foodborne illness worldwide.
