Antibiotic resistance is one of the fastest-growing threats to global health. As more bacteria evolve to evade our most powerful drugs, infections that were once easily treatable are becoming more dangerous, and sometimes untreatable.

Legionnaires’ disease may sound like a relic of the past, but outbreaks are still happening today, often silently and without warning. Caused by the bacterium Legionella pneumophila, this severe form of pneumonia poses a serious threat in large building complexes, especially hospitals, hotels, long-term care homes, and office towers.

Shigella spp. are bacterial pathogens that cause shigellosis, a gastrointestinal disease known for its highly contagious nature and severe symptoms. Shigella spreads through contaminated food, water, or direct contact with infected individuals, especially in places with limited sanitation such as shelters, schools, or under-resourced communities.

Norovirus GII is infamous for triggering rapid and disruptive outbreaks, particularly in densely populated or semi-enclosed environments like schools, cruise ships, nursing homes, and correctional facilities. Its ability to spread via food, surfaces, aerosols, and even shared spaces makes it one of the most contagious pathogens.

Food safety has never been more critical in our interconnected global economy. As supply chains stretch across continents and processing facilities scale to meet growing demand, the risk of foodborne pathogens infiltrating our food systems has increased exponentially.

Streptococcus pyogenes, commonly known as Group A streptococcus (GAS), is a versatile human pathogen responsible for a spectrum of illnesses, from mild strep throat and impetigo to life-threatening conditions like necrotizing fasciitis and streptococcal toxic shock syndrome.

Every day interactions with our pets and the food we eat can seem harmless, but hidden pathogens like Campylobacter jejuni remind us that microscopic risks are everywhere.

Clostridium perfringens is one of the most common causes of foodborne illness in the United States, sickening about one million people each year.

Prepared meals offer convenience, but they also come with food safety risks if not handled or monitored properly. On June 17, 2025, FreshRealm issued a major recall of its chicken fettuccine alfredo products due to contamination with Listeria monocytogenes, a dangerous foodborne pathogen.

Cambodia is facing a renewed public health threat as human infections with avian influenza A(H5N1) surge in 2025. With 12 confirmed cases so far this year, seven of them in June alone, health officials are sounding the alarm about increasing zoonotic transmission from poultry to humans.

Cruise ships offer a unique vacation experience, but they also present specific health challenges.

In emergency situations, shelters become a lifeline for those displaced by natural disasters, pandemics, or other crises.

In the high-stakes world of biopharmaceutical production, maintaining sterility is not just a regulatory requirement—it's essential for product safety and efficacy.

Hospital-acquired infections (HAIs) are a significant concern in healthcare facilities, posing risks to patient safety and increasing healthcare costs.

Bottled water is a staple for consumers around the world, valued for its convenience, taste, and, above all, safety.

Recreational waters, such as beaches, lakes, and rivers, provide essential spaces for relaxation and outdoor activities, attracting millions of visitors each year.

Healthcare-associated infections (HAIs) are a significant concern for hospitals, clinics, and long-term care facilities, as they impact patient health, extend hospital stays, and increase healthcare costs.

Agricultural irrigation is essential to food production worldwide, allowing farmers to grow healthy crops that feed billions of people.

Ensuring the safety of public pools and water parks is essential to protecting visitors from waterborne pathogens.
