The average retail price for fresh beef in April was $6.22 per pound — 26 cents higher per pound than it was the month before, according to the Bureau of Labor Statistics. At the same time, at the end of April, the average price for a steer was below $100 per hundred pounds; the five-year average for that same week was about $135 per hundred pounds, according to USDA’s weekly summary.

At the same time, farmers and ranchers desperate to offload their cattle as they reach optimal weight for slaughter are cutting prices so they won’t have to kill the animals without selling them.
