Title Another Flour Recall Due to Potential Salmonella Contamination
Introduction MPL Laboratories provides cGMP and ISO 17025 compliant testing services for sterility and microbial contamination in foods and beverages, pharmaceuticals, cosmetics and consumer products.
Sparta, NJ, May 23rd, 2019

Over 12,000 cases of unbleached all-purpose flour was voluntarily recalled in March due to potential microbial contamination. The recall notice, posted by the U.S. Food & Drug Administration (FDA), stated that two specific lot codes that can be found on 5 pound bags of the flour are part of the retail-level recall initiated because of Salmonella contamination concerns.

In January of this year, another popular flour producer announced a similar recall of 5 pound bags of unbleached flour. That recall was also prompted due to fears of Salmonella contamination.

The FDA reports that Salmonella, the name of a group of bacteria, is one of the most common causes of food poisoning in the United States. Usually, symptoms last 4-7 days and most people get better without treatment. But, Salmonella can cause more serious illness in older adults, infants and people with chronic diseases. Preventing foods contaminated with Salmonella from reaching consumers is essential as the Centers for Disease Control and Prevention (CDC) estimates that in the U.S. alone, infections from the bacteria cause 450 deaths, 23,000 hospitalizations and 1.2 million illnesses annually.

The laboratory specialists at MPL Laboratories provide microbial and sterility testing for a broad spectrum of contaminants, including Salmonella, E. coli, Listeria and other types of bacteria. They offer testing of raw materials, finished products and production surfaces. This type of proactive testing not only protects the public from exposure risks, it is also vital to prevent costly product recalls, damaging public relations and the expensive legal fees that are frequently associated with these types of events. Testing can also be instrumental in pinpointing the source of a foodborne outbreak if one has already taken place.
