The FDA would not say in which states the pills had been sold, but instead recommended that customers determine whether products they bought are being recalled by checking the store list on the FDA Web site, and the batch list. The batch numbers appear on the container's label.
The FDA does not recommend reading the container label to figure out if the product they bought is being recalled. 
They recommend visiting the web site, determining the batch list of recalled products, and matching that with their container's label, so they do recommend reading the label.
