Salmonella, a bacterium commonly associated with moisture-rich foods, demonstrates remarkable persistence in low-water-activity (a<0.85) products like cookie fillings, crackers, peanut butter, and spices. This survival challenges traditional food safety assumptions about dry environments. Research reveals that the interplay between water activity, food composition, and temperature creates niches where pathogens can endure for months, necessitating stringent manufacturing controls. Extended Persistence in Cookie and Cracker Fillings Studies confirm Salmonella survives in cookie and cracker sandwiches far longer than previously assumed. When inoculated into chocolate or peanut butter crème fillings (initial water activity: ~0.30), Salmonella persisted for at least 182 days (6 months) at 25°C,…

When a food recall notice arrives at a grocery store, a meticulously coordinated sequence of events unfolds to protect consumer safety. This process, governed by regulatory compliance and internal protocols, prioritizes swift containment and transparent communication. Immediate Activation of Recall Protocols Upon receiving a recall notice, typically issued by agencies like the FDA, USDA, or suppliers, stores activate a predefined recall management plan. A designated recall coordinator or team assumes responsibility for overseeing the response. This includes verifying the affected products’ details (e.g., lot codes, UPCs, “use by” dates) against inventory records. For instance, during the 2025 recall of Marketside Broccoli…

Buffets offer tempting variety but present unique food safety challenges. By understanding key risks and adopting evidence-based precautions, diners can significantly reduce their likelihood of foodborne illness. Food safety experts suggest several critical strategies: Master Temperature Control The “danger zone” between 40°F and 140°F allows bacteria to multiply rapidly. Avoid hot foods like eggs, meats, and cooked seafood that aren’t actively maintained in heated chafing dishes or on hot plates. Similarly, skip cold items like dairy products, salads, and sliced fruits if they’re not chilled on ice or in refrigerated displays. Perishable foods left at room temperature for over two…

Composting food waste transforms organic discards into valuable soil amendments but requires specific safety protocols to prevent health hazards, environmental contamination, and operational risks. These measures address pathogen control, material management, and operational safety. Pathogen Reduction through Temperature Management Hot composting, which maintains temperatures of 130° to 160°F, is critical for eliminating pathogens and weed seeds. This process relies on aerobic microorganisms breaking down materials, with sustained heat ensuring biological safety. In contrast, cold composting rarely achieves sufficient temperatures for pathogen elimination, posing higher risks if improperly managed. Monitoring with thermometers and regular pile turning maintains consistent heat distribution and…

Airline catering safety audits represent a critical safeguard in the complex journey of in-flight meals from ground kitchens to aircraft galleys. These evaluations systematically assess compliance with food safety protocols across global catering facilities that produce millions of meals daily. The audit framework combines mandatory regulatory inspections, customer-driven audits by airlines, and third-party certifications to address unique risks in aviation food handling. Multi-Layered Audit Systems The U.S. Food and Drug Administration (FDA) requires inspections of airline caterers every three to five years, though resource constraints sometimes extend this interval. During inspections, FDA officials document violations ranging from temperature control failures…

The U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) has issued a public health alert for various ready-to-eat beef jerky products from Top Notch Jerky, LLC, based in Sugar City, Idaho, due to plastic contamination. Food contaminated with foreign objects, like plastic, has the potential to cause severe harm, including choking, injury, illness, damage to teeth, or even death. Background The alert is being issued because the products are contaminated with plastic material. The contamination with plastic was discovered after consumers complained that plastic was found in the impacted products. A recall alert was not issued because the…

The explosive growth of food trucks across American cities has introduced not only new and exciting cuisines, but also unique food safety complexities as a result of their compact, mobile kitchens. These operations face distinctive sanitation hurdles compared to traditional restaurants, primarily stemming from spatial constraints and operational mobility. Temperature Control Vulnerabilities Maintaining proper food temperatures remains a critical challenge, with Suffolk County, NY, citing improper holding temperatures in 43% of food truck violations. Limited refrigeration space and power fluctuations during transit increase risks of foods entering the “danger zone” (40°F-140°F) where pathogens multiply rapidly. The confined workspace also complicates monitoring,…

A recall first announced on June 9, 2025 by Alma Pak International LLC for 400 boxes of organic blueberries due to possible Listeria monocytogenes (Listeria) contamination remains ongoing. Listeria is a bacterium that can cause serious and sometimes fatal infections, particularly in vulnerable populations such as young children, pregnant women, the elderly, and individuals with compromised immune systems. Background The recall notice said that the presence of Listeria was discovered in the finished product during routing testing by the company. The U.S. Food & Drug Administration (FDA) has classified this as a Class 1 recall, meaning that there that exposure to…

The U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) has announced a recall by Kraft Heinz Foods Company of 367,812 pounds of fully cooked turkey bacon product due to possible Listeria monocytogenes (Listeria) contamination. Listeria is a bacterium that can cause serious and sometimes fatal infections, particularly in vulnerable populations such as young children, pregnant women, the elderly, and individuals with compromised immune systems. Background The recall notice said the presence of Listeria was discovered during laboratory testing by the company. Distribution The recalled item was distributed to retail outlets in the United States and exported to both the…

Vending machines offer convenient access to snacks and beverages in workplaces, schools, hospitals, and public areas. However, like any food service system, they come with safety risks if not properly managed. These machines, which operate without on-site personnel, must adhere to strict regulations to ensure that the food they dispense remains safe for consumption. The U.S. Food and Drug Administration (FDA) regulates vending machines under the Federal Food, Drug, and Cosmetic Act, requiring that food be stored and displayed under safe conditions to prevent contamination and spoilage. Perishable items, including dairy products and sandwiches, must be kept at temperatures below 41°F…
