What Do the Recalls Say?

The FDA has recorded 2 recalls under this product code since 2008. None was by a company in China. The root cause the FDA records most often is Labeling False and Misleading (1).

A recall is a fact about one product and its maker, not a grade for every manufacturer of the type.
