DELMARVA — Federal agriculture inspectors confirmed Thursday they have detected New World screwworm in a 3-week-old calf in southern Texas near the Mexican border. It is the first verified case of the livestock parasite crossing into the United States.
Markets
The discovery sent shockwaves through cattle markets. Livestock futures surged dramatically at the Chicago Mercantile Exchange. August live cattle contracts finished $3.67 higher, closing at $241.52. October live cattle ended $4.80 higher at $233.80. August feeder cattle jumped $10.75. The gains came on oversold conditions and the screwworm news out of Texas.
Disease Concerns
In other livestock developments, highly pathogenic avian influenza outbreaks have been identified in Texas and Utah, adding to disease concerns affecting dairy operations.
Meanwhile, Illinois cattle ranchers are reporting a strong start to this year’s hay season. One rancher says the hay is abundant this year, a welcome contrast to last season’s short crop.
Local Markets
Locally, corn at Laurel Grain Company in Laurel, Delaware is bringing $4.70 a bushel for July delivery. Soybeans are $10.70 for July.
Forecast
Clear skies are expected tonight with a low around 64°. Friday brings mostly sunny conditions with a high near 81°. Fair weather continues into Saturday before a chance of showers and thunderstorms moves in Saturday night.
