Many news articles make the incorrect assumption that grass-fed beef is better for you than grain-fed beef. Here, we address ten common claims about grass-fed versus grain-fed.
1. Incorrect Claim: Grass-fed animals don’t need antibiotics.
Fact: All antibiotic use contributes to resistance in some way. The real question is whether it’s impacting public health. Multiple studies have reviewed whether antibiotic use in cattle production causes an increased risk to consumers by developing antibiotic-resistant foodborne or other pathogens, and none have found a connection. (Journal of Food Protection, July 2004; Journal of Antimicrobial Chemotherapy, 2003). Some cattle receive a class of antibiotics known as ionophores that promote the good bacteria in the rumen and help cattle better digest and use their food (kind of like a probiotic). The World Health Organization, the U.S. Food and Drug Administration and Centers for Disease Control and prevention (CDC) agree ionophores are not important to human medicine.
