Americans ate nearly 100 pounds of chicken per capita in 2020, making the fowl our favorite meat. But it’s also a favorite among bacteria, causing one in five cases of salmonella in the U.S. Biotech is helping farmers fight back.
New technology can improve detection of harder-to-spot varieties of salmonella,University of Georgia reported. The technology, CRISPR-SeroSeq, identifies the molecular signature of bacteria’s CRISPR regions, a specialized part of the DNA.
What they did: After poultry companies reported “the salmonella they find on the farms is not the same type of salmonella they find in the processing plant,” researchers investigated how and when different types of salmonella infect processed chicken.
The key finding: The more dangerous strains of salmonella identified in the processing plants were also present on the farm, but were hidden by the presence of a more common, less dangerous strain that is removed during processing.
Why it matters: The CRISPR-based technology will allow for better screening of salmonella, and inform decisions about what types of vaccines to give chickens on the farm, the study authors said.
This is not the only way CRISPR is helping chickens. Researchers at Edinburgh and Cambridge have attempted to combat avian flu utilizing gene-editing technology that is “a more precise version of the conventional selective breeding of animals,” The Guardian reported last year.
The context: The recent bird flu outbreaks have posed concerns about risks to wild and domestic birds, farmers, and human health—and emphasized the need for a One Health approach.
