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…

First Live it Up – dietary-supplement Salmonella Lawsuits have already been filed. The outbreak tied to moringa leaf powder became one of the more notable dietary-supplement Salmonella investigations of early 2026 because it expanded beyond a single brand and eventually involved two Salmonella serotypes, Salmonella Typhimurium and Salmonella Newport. According to the CDC’s final outbreak update dated March 17, 2026, investigators identified 97 illnesses in 32 states, with illnesses beginning between August 22, 2025, and February 27, 2026. Of 90 people for whom hospitalization information was available, 26 were hospitalized, and no deaths were reported. CDC stated that epidemiologic, traceback,…

Cantaloupe has earned an unfortunate place in the history of foodborne illness. For most consumers, it looks like a wholesome, familiar fruit: rough-skinned on the outside, sweet and hydrating on the inside, and commonly served fresh at breakfast buffets, hospitals, grocery stores, restaurants, and family tables. Yet over the last several decades, cantaloupe has repeatedly emerged as a vehicle for some of the most serious bacterial foodborne outbreaks in the United States, including outbreaks caused by Salmonella, Escherichia coli O157:H7, and Listeria monocytogenes. The history is not a story of a single freak event. It is a recurring pattern that…

When a foodborne illness outbreak begins, it rarely announces itself all at once. It does not usually start with a press conference, a recall, or a headline naming a specific farm, processor, restaurant, or ingredient. It begins quietly, often with scattered illnesses in different homes, clinics, and hospitals. One person develops bloody diarrhea after eating a hamburger. Another is hospitalized with Salmonella after a family meal. A child’s stool culture grows Shiga toxin-producing E. coli. A laboratory uploads genetic information into a surveillance network. A county sanitarian receives a complaint about several people who became ill after eating at the…

Chicken has occupied a peculiar and stubborn place in the history of Salmonella outbreaks. For generations, it has been one of the most widely consumed proteins in the United States, praised as affordable, versatile, and comparatively healthy. Yet at the same time, it has remained one of the foods most persistently associated with Salmonella contamination, recurring recalls, and multistate outbreaks. This history is not the story of one isolated failure or one reckless company. It is the history of an entire commodity that, because of how chickens are raised, slaughtered, processed, distributed, stored, and prepared, has repeatedly served as a…

Shiga toxin-producing Escherichia coli, commonly called STEC, is one of the most dangerous bacterial infections a child can contract from contaminated food or from contact with animals and their environment. In many cases, the infection begins like a severe gastrointestinal illness, with cramping, vomiting, and diarrhea that often becomes bloody. In a smaller but devastating number of children, however, the illness does not remain confined to the intestine. Instead, the toxins produced by the bacteria enter the body’s circulation and set off a chain reaction that damages blood vessels, destroys red blood cells, consumes platelets, and injures the kidneys. That…

Salmonella, a genus of rod-shaped, Gram-negative bacteria, stands as one of the most notorious culprits behind foodborne illnesses worldwide. Named after American veterinarian Daniel Elmer Salmon, who discovered it in 1885, Salmonella encompasses over 2,500 serotypes, with Salmonella enterica being the primary species responsible for human infections. These bacteria thrive in the intestines of animals and humans, often contaminating food through fecal matter during production, processing, or handling. Common sources include undercooked poultry, eggs, meat, dairy products, and even fresh produce like fruits and vegetables that come into contact with contaminated water or soil. Food poisoning from Salmonella, known as…

Introduction Foodborne illness is often considered an acute, self-limiting condition characterized by symptoms such as diarrhea, nausea, vomiting, abdominal pain, and fever. Most individuals recover within a few days or weeks without lasting complications. However, research over the past several decades has demonstrated that food poisoning can lead to long-term gastrointestinal disorders that persist long after the initial infection resolves. These chronic complications include post-infectious irritable bowel syndrome (PI-IBS), chronic inflammation, gut microbiome disruption, increased intestinal permeability, and functional digestive disorders. These long-term effects can significantly impact quality of life, productivity, and healthcare utilization. Understanding how foodborne infections contribute to…

Introduction Foodborne illness is commonly associated with gastrointestinal infections caused by pathogens such as Salmonella, Escherichia coli, and Listeria monocytogenes. However, botulism represents a uniquely dangerous form of food poisoning that differs significantly from typical foodborne infections. Botulism is caused not by infection, but by ingestion of a powerful neurotoxin produced by the bacterium Clostridium botulinum. This toxin affects the nervous system and can cause paralysis and death if untreated. Foodborne botulism is most often associated with improperly home-canned foods, particularly low-acid vegetables preserved without proper sterilization methods. Because of its severity, its association with preventable food handling errors, and…
