Johnson & Johnson is recalling several types of Rolaids in the U.S. because of reports of metal and wood particles in the products.

The products include Rolaids Extra Strength Softchews, Rolaids Extra Strength plus Gas Softchews, and Rolaids Multi-Symptom plus Anti-Gas Softchews. The company says the materials were potentially introduced into the products during the manufacturing process at an outside manufacturer.

The New Brunswick, N.J., company -- which has issued multiple recalls in recent months -- is suspending production of the Rolaids products in question
