WASHINGTON, September 26--President Truman, taking a stand in disagreement with some of his own party leaders, declared emphatically today price ceilings on meat should not be raised or scrapped.

With the meat shortage producing grave new complications, the President issued a statement saying:

1. The shortage is not due to price control but to an "Extraordinarily large slaughter" in July and August when price controls were temporarily off.

2. There will be a "greater quantity and better quality of meat in the near future."

3. Present livestock ceilings are "Fair and equitable."

In addition to this statement, issued at his news conference, the President told reporters he saw no need for a special session of Congress to remedy the situation. He also expressed firm hope that any growers withholding cattle and hogs will now release them for market.
