Keeping South Dakota’s Food Supply Safe: A Look Inside the Animal Disease Research and Diagnostic Laboratory
Food safety is critical—this truth resonates deeply within South Dakota’s agricultural landscape, where the Animal Disease Research and Diagnostic Laboratory (ADRDL) plays a pivotal role in safeguarding the state’s food supply. Let’s dive into the intriguing world of food testing and the tireless professionals who ensure that what ends up on your plate is not just delicious, but safe.
The Man Behind the Cart: Zachary Lau’s Mission
When Zachary Lau, a senior microbiologist at SDSU’s ADRDL, strolls through grocery stores in his state vehicle, his cart filled with beef, chicken, and seafood, he often becomes the focal point of curious glances. "Do people think I’m a bodybuilder?" Lau chuckles, reflecting on these moments.
Each month, he embarks on a unique mission: sourcing various meats and seafood to bring back to the lab for rigorous bacterial testing. This hands-on approach is not merely routine; it’s part of a larger national food surveillance effort that aims to protect consumers from harmful pathogens.
Inside the ADRDL: A Fortress of Food Safety
At the ADRDL, a constant stream of meat samples flows in from butchers and processing facilities. For places not large enough to be inspected by the U.S. Department of Agriculture (USDA), the South Dakota Animal Industry Board steps in, providing inspection services facilitated by the ADRDL.
The lab performs daily testing across a myriad of products, not just meat—think canned jellies, jams, pickles, and even raw milk! Every sampled item follows a meticulous process. Once received, samples undergo an overnight enrichment process where liquid media stimulates bacterial growth. "This step is crucial," explains Kara Hendrickson-Guttum, a research associate II, emphasizing the importance of detecting even the smallest bacterial contaminations.
What Are They Looking For?
The ADRDL specifically hunts for major culprits of foodborne illness: listeria, E. coli, salmonella, and campylobacter. Although positive results are infrequent, they do occur. What happens next? A rigorous confirmation process isolates the bacteria to ensure accurate identification—vital for public safety. As Laura Ruesch, a research associate III, elaborates, this ensures only actionable findings reach stakeholders, helping to prevent potential recalls before they escalate into a public health crisis.
The Role of Technology in Food Safety
Innovation is key in the ever-evolving field of food safety. Ruesch, who began her journey in the ADRDL as a student, highlights the technological advancements that have transformed testing methods over the years. From enzyme-linked immunosorbent assay to cutting-edge polymerase chain reaction testing, the lab’s capabilities have significantly improved.
Less than a decade ago, the accuracy of tests was a growing concern. Now, with triggered advancements, false positives have decreased, saving resources for producers and enhancing consumer trust. This is particularly relevant in a landscape where a Gallup poll revealed a growing public skepticism towards federal food safety efforts.
National Collaboration: The Federal Emergency Response Network
In response to significant threats, such as the events of September 11, the U.S. government established the Federal Emergency Response Network, and since 2005, the ADRDL has been an integral part of this initiative. The lab has assisted in various applauded efforts, including testing during widespread food recalls. Through GenomeTrakr, the lab contributes to public health by sequencing the genomes of pathogens to efficiently track and analyze foodborne illness outbreaks nationwide.
A Commitment to Community
Yet, despite the impressive technological infrastructure, the heart of the ADRDL is its commitment to the local community. Hendrickson-Guttum expresses pride in aiding local producers and small businesses, particularly during the challenges posed by the COVID-19 pandemic. The surge in demand for local processing highlighted the tremendous need for reliable testing support—ensuring that consumers could access safe, locally-sourced foods.
“That connection keeps us grounded,” Ruesch adds. “We’re big enough to have advanced technology but small enough to maintain our personal touch with the food industry.”
Conclusion: A Bright Future for Food Safety in South Dakota
In a world where food safety concerns loom large, the ADRDL’s commitment to safeguarding South Dakota’s food supply is commendable. Through rigorous testing, innovative technology, and a heartfelt connection to local producers, this unique laboratory stands at the forefront of food safety.
Whether you’re a consumer or a small business owner, it’s reassuring to know that dedicated experts like Zachary Lau and his team are working tirelessly to ensure that every bite you take is both delicious and safe.
