How important is pet food safety to the average American? The American Pet Products Association has estimated that 70% of U.S. households own a pet, including more than 100 million households with at least one dog or cat. In recent years, consumer demand for premium and specialty pet food products has fueled a spike in U.S. sales of pet food to nearly $30 billion annually. Due to the growing consumer demands for high-quality pet food and an increasingly complex pet food supply chain, it seems the safety of animal food has never been more important.
The beginning of the year brings a time to evaluate the previous year and set resolutions for the next twelve months. As you examine the internal processes at your facility, consider the environmental monitoring data that you put so much time and money into generating. How can you extract greater value from that data to improve your food safety program? Let’s resolve to go beyond reviewing “new” CoAs, updating a spreadsheet of “hot spots” and filing that information away where it’s unlikely to be reviewed again. Continue Reading
A new draft guidance, “Control of Listeria monocytogenes in Ready-To-Eat Foods: Guidance for Industry” was published by the US Food and Drug Administration (FDA) on January 13, 2017. Comments for this guidance were due July 26 and many trade associations and food manufacturers have submitted remarks. This draft guidance offers some excellent background information about Listeria control – more than simply using an environmental monitoring program (EMP). It also includes detailed coverage of many of the prerequisite programs (Good Manufacturing Practices) that are integral for Listeria control. In addition, it provides a comprehensive compilation of industry best practices and includes information about the validation of listeriostatic or listeriocidal formulations and processes.

Technical Tuesday: Does Serotyping Have Value in Modern Salmonella Food Contamination Investigations?Dave Evanson /
The identification and differentiation of bacteria date back to the late 1800s. Primary interest often focused on microorganisms impacting animal or human health. Salmonella falls under this umbrella, as it was first identified during a hog cholera study in the 1880s. Early work relied on phenotypic (observable) characteristics due to the limitations of the science at the time, but advancements in science led to the initial development of an antigenic schema for Salmonella. Over the ensuing years, the use of phenotypic and antigenic characteristics helped define the taxonomy of Salmonella (>2600 serovars). These characteristics have also been used for decades in public health investigations involving foodborne illnesses. Linking a Salmonella isolate from an ill human to a Salmonella isolate from a food through serotyping played a critical role in these investigations. Continue Reading
Major developments in the Food Safety Modernization Act (FSMA) have given the FDA new authority under the law. If the FDA decides to conduct a swabathon at your facility, you should expect a minimum of 100 to 300 swabs to be taken and a team of several investigators to conduct the swabathon. Based on the type of swabathon, you may also be required to hold production in your facility. This need is based on several factors, but, in particular, the zones that will be tested.
The FDA’s goal is to find pathogen isolates of Salmonella and or Listeria monocytogenes in and around the processing environment. As an outcome, the FDA will subsequently perform Whole Genome Sequencing (WGS) on these Listeria monocytogenes isolates for their database. The FDA is now swabbing Zone 4 specifically for this purpose, with a WGS analysis of Salmonella expected to follow. The FDA’s zone focus will differ based on the environment and the specific pathogen they are seeking out. For Listeria monocytogenes, you can expect the FDA to begin sampling no sooner than 4 hours into production. Continue Reading
I recently attended the annual meeting for the International Association for Food Protection (IAFP) in Tampa, Florida. I always enjoy attending the food safety sessions, as well as seeing old friends from across the food industry. My presence at numerous IAFP meetings over the years has afforded me the chance to seek out new EnviroMap customers, but it has also given me the opportunity to speak with many legacy customers.
EnviroMap was developed several years ago, so our time at IAFP helps us move the product forward and provides insight on its real-world application. We have customers who use it for finished products as well as environmental testing. Some feel that the best feature of EnviroMap is reporting, while others claim it is the control/visibility over their local environmental program as well as their enterprise environmental management. I’m also fairly certain the local plant folks would all agree it has made their lives easier and freed up time to devote to other tasks. Continue Reading
Many companies have Environmental Monitoring Programs (EMPs) setup to monitor the processing (and surrounding) environments for transient pathogens such as Listeria monocytogenes and Salmonella. However, it is important to realize that growth niches are likely to occur from these transient guests. If your EMP does not include a “seek and destroy mission,” an event section, (i.e. increasing swab surveillance with roof leaks, construction, etc) or is simply not robust enough, then routine monitoring may be insufficient protection against an FDA swabathon. Additionally, if your site selection is fixed, new sites aren’t being rotated in, a low number of swabs are being taken, you have an infrequent swabbing schedule and corrective actions are not being implemented, the same result will surely occur.
The top priority for most food manufacturers is protecting the food consumers eat. Yet, one of the major causes of product recalls in the food industry is product contamination in the processing environment by pathogens such as Salmonella and Listeria monocytogenes. These pathogens take up residence within the structure of food plants and within the processing equipment itself. Once it makes a home there, it can contaminate the food products it comes into contact with as they make their way through the production process. Continue Reading
