NEW YORK (Reuters) - Lawmakers will hold a hearing on Johnson & Johnson's recall of Children's Tylenol and other over-the-counter medicines later this month, and have asked the company's CEO to testify.

The House Committee on Oversight and Government Reform will hold a hearing on May 27, and has asked J&J Chief Executive William Weldon to testify, according to the panel's website.

The company recently recalled 40 widely used children's pain and allergy medications, saying some may have a higher concentration of their active ingredients, while others may be contaminated. J&J has had four recalls in the past year of over-the-counter medicines.

Food and Drug Administration inspectors have said they found thick dust, grime and contaminated ingredients at the J&J plant that produces Children's Tylenol and dozens of other products.

J&J has called the manufacturing problems unacceptable and vowed to fix them. The company has suspended production at the Pennsylvania plant where the recalled children's products are made.
