Following the recent string of product recalls for healthcare manufacturer Johnson & Johnson, the company has faulted lax cleaning procedures and other issues at a manufacturing plant as the culprit for massive recalls of over-the-counter medications, such as Tylenol. The company said it was voluntarily recalling nearly 50 million more units of consumer medications.

Just last week, Johnson & Johnson recalled packages of various kinds of Tylenol, Benadryl, Rolaids and other products and last month, the company recalled all batches of Softchews Rolaids made by an outside manufacturer after wood and metal bits were discovered in the tablets.

J&J’s image has been recently tarnished by repeated recalls totaling nearly 200 million bottles in the past year and could be faced with criminal charges from the U.S. Department of Justice. The recalls have also impacted the company’s bottom line, and has led J&J to seek buyers for some of its brands.
