Johnson & Johnson is creating a new position to oversee companywide quality, manufacturing and compliance issues, and is appointing chief quality officers for each of its three major business units.

The moves come as the health care giant’s once-stellar reputation for quality is being tarnished by repeated recalls of nonprescription medicines.

J&J on Wednesday named corporate Vice President Ajit Shetty to oversee the push for quality improvements in its pharmaceutical, consumer products and medical device and diagnostics groups.

Since September, the New Brunswick, N.J., maker of Band-Aids and Tylenol has announced eight different recalls. They cover tens of millions of bottles of pain relievers Tylenol, Motrin and St. Joseph aspirin, allergy drug Benadryl, heartburn tablets Rolaids and Simply Sleep pills.

The recalls involved products made at both a Fort Washington, Pa., factory shut down in April — and expected to remain closed for another year while it is upgraded — and another factory in Las Piedras, Puerto Rico.
