A big snow storm that began early Friday caused several meat plants to curtail operations in Texas, Oklahoma and Kansas.

The National Weather Service said the storm should continue through Saturday morning. Forecasts called for 8 to 18 inches of snow from the Texas panhandle north through western Kansas.

Seaboard Corp (SEB.A) said its hog and pork plant at Guymon, Oklahoma, was not operating on Friday because of the snowstorm and a decision would be made later on Friday if the plant would operate on Saturday.

The Seaboard plant has a daily slaughter capacity of about 19,000 hogs.

In addition, Tyson Foods Inc said its beef plants at Amarillo, Texas, and Finney County, Kansas, would not operate on Friday because of the storm.

The storm also caused the JBS-Swift beef plant at Cactus, Texas, to be closed on Friday.
