Grass-fed cattle will not shed E. coli.

Explanation:
The ability to shed E. coli is not eliminated by a grass-based diet. Cattle harbor E. coli in their intestines and can shed it in their feces regardless of whether they are grass-fed or grain-fed. Diet can influence gut microbial populations and possibly the level of shedding, but it does not guarantee zero shedding. Pathogenic strains like E. coli O157:H7 can be present in healthy grass-fed cattle, so the idea that grass-fed cattle will not shed E. coli is not supported. This is why the statement is false: shedding can occur across feeding regimens, and human risk is more tied to contamination during slaughter and processing, along with proper cooking and hygiene.
