August live cattle futures fell $1.40 to $245.825 and feeders lost $3.45 to $369.825 on Friday, with profit-taking led by feeders. NWS cases in the US rose to 27, all in Texas and New Mexico, and a sterile fly plant opened in Chiapas, Mexico.
Expanding screwworm cases keep cattle supplies tight and support prices, while the sterile fly plant could eventually ease the threat and limit upside over time.
