The transition to cold, wet conditions with large fluctuations in temperatures bring physical stress and closely packed herds where animals will hide their symptoms and share diseases. However, cold temperatures are no excuse to just treat, record and move on.

Is overlap of antibiotics used in both animal and human health a threat to humans? Maybe, but I will try and explain why I do not think it is near the threat that some opposed to modern agriculture claim it is.
