The simple act of preparing a meal harbors a surprisingly common and dangerous risk: cross-contamination. This unseen threat occurs when harmful bacteria from raw foods like meat, poultry, or seafood spread to ready-to-eat items such as salads, fruits, or cooked dishes via contaminated hands, utensils, cutting boards, or countertops. Recognizing this pervasive hazard, the Hong Kong Centre for Food Safety (CFS) has launched its annual Food Safety Day (FSD) 2025 campaign under the critical theme “Preventing Cross-contamination”. This initiative, closely aligned with the UN’s World Food Safety Day (June 7th), highlighted a global effort to combat foodborne illnesses, which sicken an alarming 1.6 million people…
A recall first announced on July 15, 2025 by Newly Weds Foods, Inc., based in Chicago, Illinois for various bread products 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 How the potential presence of Listeria was found in the impacted products was not announced. Distribution The recalled items were distributed in Florida, Idaho, Illinois, Kansas, Missouri, New York, Oregon, Texas, Washington, and Canada.

Personalized nutrition utilizing genetic testing has expanded consumer access to customized dietary recommendations, but this approach introduces distinct food safety considerations that differ from conventional nutrition guidance. As direct-to-consumer genetic testing grows annually by 11.6%, regulatory and scientific communities are examining potential risks associated with gene-based dietary advice. Scientific Validity Concerns The predictive value of nutrigenomic tests varies significantly across genes and conditions. While certain gene-nutrient interactions like MTHFR variants affecting folate metabolism have stronger scientific backing, many commercial tests analyze genes with insufficient clinical evidence for dietary applications. The field faces challenges in establishing standardized validation protocols and demonstrating consistent health…
Advanced sensor technology, known as electronic noses (e-noses), is increasingly replacing static expiration dates by providing real-time, objective assessments of food freshness. These systems detect volatile organic compounds (VOCs) released during microbial growth, identifying spoilage before it becomes perceptible to human senses. Technology Fundamentals and Sensor Types E-noses operate using arrays of chemical sensors that react to specific VOCs associated with decay: These sensor arrays generate unique composite response patterns (“fingerprints”) for different spoilage states. Machine learning algorithms compare these patterns against databases of known spoilage profiles to determine freshness. Data Processing and Machine Learning Accurate spoilage detection requires sophisticated data analysis…
Rising temperatures and humidity are accelerating pathogen growth in street foods across global megacities, pushing vendors in Mumbai, Lagos, and Bangkok to deploy innovative solutions to protect public health. As climate change intensifies, these cities, where street food sustains millions daily, are becoming testing grounds for adaptive strategies against foodborne illnesses. Climate Pressures on Street Food City-Specific Innovations Mumbai, India Vendors are adopting centralized “clean food hubs” with regulated cold storage and UV-treated water for washing produce. Following climate-linked outbreaks during 2018 floods, the city piloted mobile apps providing vendors with real-time weather alerts and food safety reminders. Rice and dairy-based dishes,…
Public health officials and food safety experts highlight essential measures to prevent foodborne illness outbreaks at weddings, corporate gatherings, and other large catered events. Multiple incidents underscore the risks, including a cruise ship owner’s wedding where guests required medical treatment and a Missouri event that sickened approximately 300 attendees due to suspected food safety failures. Selecting and Vetting Caterers: The primary defense is choosing a reputable, licensed caterer. Event organizers should inquire about the caterer’s food safety practices. Key questions include: where food will be prepared (a licensed kitchen versus home kitchen), procedures for transporting food while maintaining safe temperatures (using insulated…
A voluntary recall by Doehler Dry Ingredient Solutions, LLC, based in Cartersville, Georgia, has been issued for Member’s Mark Freeze Dried Fruit Variety Pack 15 count boxes 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 potential presence of Listeria was found through internal company testing. Distribution The recalled items were distributed through Sam’s Club retail stores and sent to distribution centers in the following states: AL, AZ, CA, CO, CT,…
Health authorities in the United Kingdom have reported a significant increase in deadly E. coli infections, with cases rising 26% to 2,544 in 2024. The surge follows a major outbreak linked to contaminated salad leaves that resulted in two deaths and widespread illness across the UK, according to multiple media sources. Last Summer, Food Poisoning News reported on an outbreak of E. coli in the UK that, at the time, had affected over 100 people but no linked product had been found. The salad contamination outbreak generated 196 cases, with 11 individuals developing life-threatening complications and 126 requiring hospitalization. The incident prompted…
A voluntary recall has been issued by the Canadian Food Inspection Agency (CFIA) and The Butcher Shoppe, based in Ontario, Canada, for genoa salami and soppressata hot salami both sliced by the pound due to potential Salmonella contamination. Salmonella is a bacterium that can cause serious infections in animals and humans, especially those in vulnerable populations such as young children, the elderly, and individuals with compromised immune systems. Background How the presence of Salmonella in the impacted products was discovered was not announced. This recall is likely related to an outbreak of Salmonella in Canada connected to other salami products. Distribution The recalled product…
Hotel ice buckets and ice machines present significant foodborne illness risks to guests when sanitation protocols are inadequate, according to industry reports and scientific studies. These risks stem from multiple contamination points across ice handling and storage systems. Ice Bucket Hazards Hotel ice buckets frequently harbor biofilms, slimy microbial accumulations, due to improper cleaning between guests. Industry observations indicate that staff often rinse buckets with water alone rather than using sanitizing solutions or dishwashers. Compounding this issue, guests sometimes repurpose ice buckets for non-food uses including as vomit containers, trash bins, foot baths, or even makeshift toilets, introducing pathogens directly into containers…
