Recalled beef that had been meant for public school lunches will be dumped at the Waimanalo Gulch landfill in West O'ahu beginning this morning. The process of dumping as many as four loads could take two days to complete.

The state Department of Health will oversee the disposal of the 3,700 cases, each weighing 40 pounds, in the landfill.

Two Mainland meat-packing companies have been barred from supplying school lunch and other programs while federal investigators look into videotapes showing workers mistreating sick dairy cows.

One of the companies is a major supplier to the USDA program that distributes beef to needy families, the elderly and schools through the National School Lunch Program.
