New Biological Treatment Improves Food Safety


dairy cattleA new biological treatment could prevent dairy cattle from getting uterine diseases, which would, in turn, improve food safety for people.

UF/IFAS researcher Kwang Cheol “KC” Jeong and Klibs Galvao have conducted both lab and field experiments.

The research team infused chitosan microparticles, an antimicrobial material made of dissolved shrimp shells – into diseased cow uteri. They found that chitosan decreased multiple pathogenic bacteria, including Fusoscobacteria necrophorum, in the uterus and cured metritis, an inflammation in the uterus.

Jeong said more research is needed, but it may be possible for chitosan microparticles to be used to help humans who have become ill from consuming E coli-contaminated food.
