Chinese researchers discover an environmental virus capable of eliminating salmonella

Chinese researchers have confirmed that salmonella

 bacteria, responsible for food contamination and resistant to antibiotics, can be neutralized using a naturally occurring virus found in the environment. This discovery opens a new pathway to enhance food safety and combat antibiotic resistance worldwide.

According to a report relayed by Sky News and published in the journal Applied and Environmental Microbiology, the bacteriophage “W5” acts like a highly precise guided missile, capable of eliminating harmful salmonella found on food and packaging materials. It can also destroy biofilms on milk, meat, and eggs under storage conditions that simulate real-life environments.

In this context, Huitian Guo, head of the research team at Gansu Agricultural University, stated that this eco-friendly solution leaves no harmful chemical residues. Studies are currently underway to explore its use in animal feed, as a surface disinfectant in processing plants, or as a spray to preserve fresh products throughout the food supply chain.

This discovery opens promising prospects for addressing growing health threats, particularly salmonella, which causes thousands of infections and deaths each year. Bacteriophages could thus represent a strategic alternative to traditional antibiotics in protecting global food security.
