Recently, multiple foodborne outbreaks caused by shiga toxin-producing E. coli (STEC) have been epidemiologically linked to the consumption of wheat flour. This has been a hot topic of discussion with many of our flour milling clients as well as manufacturers and retailers who use flour as an ingredient or sell flour to consumers. Many in the food industry are wondering if they should be changing their hazard analyses, environmental monitoring programs, ingredient testing or finished product testing. Continue reading Technical Tuesday: Recalls Raise Concerns About Shiga Toxin-Producing E. coli in Flour
When consumers purchase chicken from the grocery store, they could be bringing home more than just a drumstick. Campylobacter has crept its way up the charts to become the top bacterial cause of reported foodborne illnesses in the United States. Move over, Salmonella! But how does Campylobacter infiltrate the food supply, and why is it seemingly on the rise? We’ve answered five need-to-know questions about Campylobacter below: Continue reading Don’t Play ‘Chicken’ With Foodborne Illness: 5 Campylobacter Questions Answered
I once jokingly said during a presentation that there were at least 10 ways to sabotage your food pathogen testing program. While no conscientious food safety leader would set out to negatively impact their own program, the high attention to detail and constant organizational discipline required for an effective testing program leave some room for error. If any small step is not well designed and expertly executed, then your entire program may be worthless – or worse – may cost you millions due to a recall or human illnesses. One factor in particular that manufacturers need to focus their attention on is the reliability of their pathogen sampling and compositing (pooling) strategy, as well as the applicability of their pathogen method. Specifically, what test portion should be taken to ensure accurate results, and what method should be used when testing for the presence of pathogens?

In preventing foodborne illnesses, several different factors play a pivotal role in safeguarding final products. Several recent recalls associated with Listeria monocytogenes are prompting food manufacturers to ensure their food safety management plans address all possible sources of in-plant contamination.
Listeria can be life-threatening to individuals with weakened immune systems, pregnant women or older adults. Dairy, prepared foods, produce and seafood were the matrices most commonly contaminated with Listeria over the past five years, according to data from the latest FDA Reportable Food Registry (RFR) report. Continue reading Preventing Listeria and Other Pathogens in Food Production
Over the past decade, the food testing industry has adopted new methods and strategies to reduce turn-around-time and the total duration of testing methods. In addition to the tests themselves, many other factors must be considered when referencing total turn-around-time and the amount of time spent by your staff in filling out and submitting laboratory testing forms.
For a majority of laboratories, turn-around-time begins when the sample is received to start testing. Turn-around-time can be reduced logistically by the use of expedited shipping services and couriers, but the laboratory itself must manage processing the samples in a timely fashion once they hit the laboratory door. Continue reading Optical Character Recognition – Improving the Sample Submission Process
Campylobacter is a less commonly known organism that has quickly become an emerging hot topic in food microbiology in recent years due to various recalls, news articles and evolving government regulations. Surprisingly, this genus of spiral-shaped, microaerophilic bacteria is the most commonly reported bacterial cause of gastroenteritis from foodborne sources in the United States, outranking E. coli, Salmonella, Staphylococcus aureus and other more well known microorganisms. Continue reading Spotlight on Campylobacter
