Hi Pierce and Trinity,

Thank you for leading the discussion and writing a great summary of the MGR last week.

The role of antibiotics in agriculture contributing to antibiotic resistance was something that stood out to me in the MGR last week. The federal government recently created regulations requiring farmers to obtain a prescription from a veterinarian for medically important antibiotics for livestock. 1 Medically important antibiotics include those used to treat human infections, and importance is also affected by whether alternatives exist for the antibiotic. 1 This regulation aims to increase veterinarian oversight of agricultural antibiotic use and reduce the use of antibiotics in livestock, especially those important for treating human disease. Interestingly, lab-grown meat would likely require significantly less antibiotics compared to livestock. 2 Risk of exposure to bacteria is reduced by sterile lab conditions and cellular agriculture is much faster, reducing the potential for bacterial exposure. 3 Additionally, a widespread shift from traditional to lab-grown meat would decrease the number of livestock and reduce contact between humans and animals, lowering the risk of zoonotic diseases. 3 I’m not sure if lab-grown meat will be popular, but it sounds like it would help combat agriculture-related antibiotic resistance! I look forward to hearing everyone’s thoughts on other methods to reduce antibiotic use in agriculture.

All the best,
