About Hantavirus Hantavirus is not the kind of disease most people expect to hear about on a cruise ship. Cruise outbreaks are usually associated with norovirus, contaminated food, unsafe water, or close-contact respiratory infections. But this month, May 2026, a suspected hantavirus cluster aboard the MV Hondius, a polar expedition cruise ship traveling between Argentina and the Canary Islands, drew international attention after several passengers developed severe respiratory illness. According to the World Health Organization, the cluster was reported on May 2, 2026; by May 4, seven cases had been identified, including two laboratory-confirmed hantavirus infections, five suspected cases, three…

Texas Botulism Lawyer Ron Simon on the ByHeart Outbreak ByHeart Whole Nutrition Infant Formula, once marketed to parents as a premium infant nutrition product, became the center of national concern after federal health officials linked the product to a multistate infant botulism outbreak. The recall ultimately expanded to include all ByHeart Whole Nutrition Infant Formula products, including formula cans and single-serve “anywhere pack” sticks, according to the FDA’s outbreak investigation. The CDC later reported that the outbreak included confirmed and probable infant botulism cases and that all ByHeart Whole Nutrition Infant Formula products had been recalled, while also warning families…

Salmonella is one of the most important causes of food poisoning worldwide. It is responsible for millions of infections each year and remains a major public health concern across both developed and developing countries. Understanding Salmonella requires looking at its biology, transmission, symptoms, and especially the different strains (serotypes) that drive outbreaks. What Is Salmonella? Salmonella is a genus of bacteria belonging to the Enterobacteriaceae family. It consists primarily of two species: Within these species, there are over 2,500 different serotypes (strains). Most human illnesses are caused by Salmonella enterica. The Disease: Salmonellosis Infection with Salmonella causes salmonellosis, a type…

Organic food has become synonymous with health, purity, and safety in the minds of many consumers. Grocery stores prominently display organic labels, often at a premium price, and consumers frequently choose them believing they are less likely to cause illness. One of the most common assumptions is that organic foods carry a lower risk of food poisoning compared to conventionally produced foods. However, when examined scientifically, the relationship between organic food and foodborne illness is far more nuanced—and sometimes counterintuitive. What “Organic” Actually Means The term “organic” refers to how food is produced, not how safe it is. Organic farming…

The Scope of Foodborne Outbreaks Foodborne outbreaks can arise from a wide range of pathogens, including Salmonella, Escherichia coli, and Listeria monocytogenes. These outbreaks often involve widely distributed food products, meaning that a single point of contamination can affect consumers across multiple states or even countries. The complexity of modern food supply chains increases the risk of widespread outbreaks. Ingredients may be sourced from multiple locations, processed in centralized facilities, and distributed through extensive networks. Without a clear plan in place, identifying the source of contamination can be time-consuming and difficult, allowing the outbreak to grow. Why Preparedness Is Essential…

Introduction Foodborne illness outbreaks require coordinated efforts across multiple levels of government to identify sources, contain spread, and protect public health. While national agencies such as the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) play critical roles in surveillance and regulation, local health agencies serve as the “boots on the ground” in outbreak investigations. Their direct interaction with affected communities makes them indispensable in identifying cases, collecting data, and implementing control measures. Without the active involvement of local agencies, national-level investigations would lack the detailed, real-time information necessary to effectively trace and control…

Post-infectious irritable bowel syndrome (PI-IBS) is a well-documented condition that develops following an episode of acute gastrointestinal infection, often caused by bacteria such as Salmonella, Escherichia coli, or Campylobacter. While many individuals recover fully after foodborne illness, a significant subset go on to experience persistent gastrointestinal symptoms consistent with irritable bowel syndrome (IBS). Understanding when PI-IBS is most likely to occur, who is at greatest risk, and the mechanisms behind its development is critical for both prevention and long-term patient management. What Is Post-Infectious IBS? IBS is a functional gastrointestinal disorder characterized by chronic abdominal pain, altered bowel habits (diarrhea,…

Hemolytic uremic syndrome (HUS) is a serious and potentially life-threatening condition that often develops as a complication of foodborne illness, particularly infections caused by Shiga toxin–producing bacteria such as Escherichia coli O157:H7. Although many cases of food poisoning resolve without long-term consequences, HUS represents a severe progression that can result in kidney failure, neurological complications, and even death. Understanding when HUS occurs, who is most at risk, and how it develops is critical for both prevention and clinical management. What Is Hemolytic Uremic Syndrome? HUS is a condition characterized by three primary features: These features result from damage to small…

Introduction Escherichia coli (E. coli) is one of the most commonly implicated bacterial pathogens in foodborne illness, particularly associated with undercooked or contaminated meat. A widespread misconception is that freezing meat eliminates harmful bacteria. In reality, freezing does not reliably kill E. coli, and improper handling of frozen meat can still result in infection. Understanding how E. coli behaves at freezing temperatures—and how to safely handle frozen meat—is essential for preventing illness. What Is E. coli? E. coli is a diverse group of bacteria naturally found in the intestines of humans and animals. While most strains are harmless, certain pathogenic…

Introduction Salmonella is one of the leading causes of foodborne illness worldwide, commonly associated with poultry, eggs, and contaminated produce. While many infections are self-limiting, severe cases may require antibiotic treatment. In recent decades, however, the emergence of antibiotic-resistant Salmonella strains has become a major public health concern, complicating treatment and increasing the risk of severe outcomes. What Is Salmonella? Salmonella is a genus of bacteria that infects the intestinal tract. The most common species affecting humans is Salmonella enterica, which includes numerous serotypes such as Enteritidis and Typhimurium. Symptoms of salmonellosis typically include: Symptoms usually develop within 6–48 hours…
