UPDATE 1-J&J chief won't testify at US House Tylenol hearing
* CEO Weldon recovering from back surgery
* Another J&J official prepared to testify instead
* House committee says hearing still on
WASHINGTON, May 19 (Reuters) - U.S. House lawmakers will not hear from Johnson & Johnson (JNJ.N) chief executive William Weldon at next week's hearing on recalled children's products, as he recovers from back surgery.
J&J spokeswoman Carol Goodrich said Weldon had surgery on Wednesday, but was willing to communicate with the House Oversight and Government Reform Committee about the recalled Tylenol and other products at a later date.
J&J's Worldwide Chairman of the Consumer Group Colleen Goggins is prepared to testify instead, Goodrich said.
Despite calls from some Republicans to postpone the hearing, Democratic Chairman Edolphus Towns said earlier on Wednesday the May 27 hearing would go on as scheduled.
The hearing comes after J&J announced a widespread recall of its liquid Tylenol, Motrin, Benadryl and Zyrtec products for infants and children on April 30. FDA later announced agency investigators had uncovered numerous violations at the company's Fort Washington, Pennsylvania plant.
Lawmakers have also invited U.S. Food and Drug Administration Commissioner Margaret Hamburg to testify, but an agency spokeswoman could not confirm whether Hamburg would appear. (Reporting by Susan Heavey; editing by Andre Grenon)
