Listeria, a bacterium responsible for listeriosis, presents a significant concern due to its relatively high mortality rate, leading to approximately 260 deaths annually in the United States, according to the Centers for Disease Control. Unlike some isolated super-bug, Listeria monocytogenes is commonly found in soil and water, and animals can carry the bacterium without showing signs of illness, potentially contaminating foods of animal origin. Moreover, when Listeria enters a food processing factory, it can persist for years, posing a threat to food products. Consumers and food processors alike are keenly aware of the need for effective prevention measures. While consumers can refer to resources like the CDC and FDA for prevention information, food processors must focus on stringent practices and standards. Areas such as cleaning and sampling, ensuring proper temperatures during processing, and implementing strategies to prevent cross-contamination play a crucial role in minimizing the

Pick the right meter. A pH meter with more than minimum requirements may be the better option. Product requirements and regulations change with time. Meters with advanced features will allow for a wider range of testing and documentation of results.
Know the basics. The meter's algorithm and displayed value expresses the amount of potential difference between the electrode’s reference to a sample being tested. During the process of electrode equilibrium (or end-point), a blockage or slowing of an electrode’s reference junction can impact the electrode's ability to perform its task.Remember electrodes need to be rinsed and blotted before each test.
Maintenance is critical. Periodic and proper cleaning is required. Protein and other contaminants can build up on the electrode reference junction or sensing areas, often resulting in a longer time to endpoint. Cleaning solutions specifically designed for differing electrode
