INDIANAPOLIS, Aug. 8, 2017 /PRNewswire/ -- Pharmaceutical recall activity saw a disturbing rise not only in the volume of products recalled last quarter, but also in the severity of risk to consumers, according to the latest Recall Index released today by Stericycle ExpertSOLUTIONS (NASDAQ: SRCL ). More than a hair out of place Pharmaceutical recalls increased 6 percent over the previous quarter to 86. More jarring, the volume of recalled drug units circulating in homes and store shelves climbed 444 percent over the previous quarter, making it the most active quarter since Q4 2014. Most concerning was the number of recalls for Class I situations, safety issues that pose the highest risk of serious adverse consequences or death, according to the Food and Drug Administration (FDA). There were 11.6 million Class I pharmaceutical units recalled in Q2, making it the highest since at least 2004.
