This is a list of foodborne illness outbreaks by death toll, caused by infectious disease, heavy metals, chemical contamination, or from natural toxins, such as those found in poisonous mushrooms. Before modern microbiology, foodbourne illness was not understood, and, from the mid 1800s to early-mid 1900s, was perceived as ptomaine poisoning, caused by a fundamental flaw in understanding how it worked. While the medical establishment ditched ptomaine theory by the 1930s, it remained in the public consciousness until the late 1960s and early 1970s.
Outside of botulism (which has been well known since the early 1900s and killed often at the time), many other foodbourne illnesses such as salmonellosis were not monitored closely or kept careful track of until at least the late 1970s, with overall monitoring only fully taking off after the 1992–1993 Jack in the Box E. coli outbreak.

Listeria monocytogenes is the species of pathogenic bacteria that causes the infection listeriosis. It is a facultative anaerobic bacterium, capable of surviving in the presence or absence of oxygen. It can grow and reproduce inside the host's cells and is one of the most virulent foodborne pathogens. Twenty to thirty percent of foodborne listeriosis infections in high-risk individuals may be fatal. In the European Union, listeriosis continues an upward trend that began in 2008, causing 2,161 confirmed cases and 210 reported deaths in 2014, 16% more than in 2013. In the EU, listeriosis mortality rates also are higher than those of other foodborne pathogens. Responsible for an estimated 1,600 illnesses and 260 deaths in the United States annually, listeriosis ranks third in total number of deaths among foodborne bacterial pathogens, with fatality rates exceeding even Salmonella spp. and Clostridium botulinum.
Foodborne illness is any illness resulting from the contamination of food by pathogenic bacteria, viruses, or parasites, as well as prions, and toxins such as aflatoxins in peanuts, poisonous mushrooms, and various species of beans that have not been boiled for at least 10 minutes.
Listeria is a genus of bacteria that acts as an intracellular parasite in mammals. As of 2024, 28 species have been identified. The genus is named in honour of the British pioneer of sterile surgery Joseph Lister. Listeria species are Gram-positive, rod-shaped, and facultatively anaerobic, and do not produce endospores.
Listeriosis is a bacterial infection most commonly caused by Listeria monocytogenes, although L. ivanovii and L. grayi have been reported in certain cases. Listeriosis can cause severe illness, including severe sepsis, meningitis, or encephalitis, sometimes resulting in lifelong harm and even death. Those at risk of severe illness are the elderly, fetuses, newborns and those who are immunocompromised. In pregnant women it may cause stillbirth or spontaneous abortion, and preterm birth is common. Listeriosis may cause mild, self-limiting gastroenteritis and fever in anyone.
A product recall is a request from a manufacturer to return a product after the discovery of safety issues or product defects that might endanger the consumer or put the maker or seller at risk of legal action. Product recalls are one of a number of corrective actions that can be taken for products that are deemed to be unsafe.
Boar's Head Provision Co., Inc. is a supplier of delicatessen meats, cheeses and condiments. The company was founded in 1905 in Brooklyn, New York, and now distributes its products throughout the United States. It has been based in Sarasota, Florida, since 2001.
The 2008 Canadian listeriosis outbreak was a widespread outbreak of listeriosis in Canada linked to cold cuts from a Maple Leaf Foods plant in Toronto, Ontario. There were 57 total confirmed cases, resulting in 23 deaths.
Adulteration is a legal offense and when the food fails to meet the legal standards set by the government, it is said to have been Adulterated Food. One form of adulteration is the addition of another substance to a food item in order to increase the quantity of the food item in raw form or prepared form, which results in the loss of the actual quality of the food item. These substances may be either available food items or non-food items. Among meat and meat products some of the items used to adulterate are water or ice, carcasses, or carcasses of animals other than the animal meant to be consumed. In the case of seafood, adulteration may refer to species substitution (mislabeling), which replaces the species identified on the product label with another species, or undisclosed processing methods, in which treatments such as additives, excessive glazing, or short-weighting are not disclosed to the consumer.
The 2011 United States listeriosis outbreak was a widespread outbreak of Listeria monocytogenes food poisoning across 28 US states that resulted from contaminated cantaloupes linked to Jensen Farms of Holly, Colorado. As of the final report on August 27, 2012, there were 33 deaths and 147 total confirmed cases since the beginning of the first recorded case on July 31, 2011. It was the worst foodborne illness outbreak in the United States, measured by the number of deaths, since the Centers for Disease Control and Prevention began tracking outbreaks in the 1970s, or tied with the worst, an outbreak of listeria from cheese in 1985, depending on which CDC report is used.
The 1996 Odwalla E. coli outbreak began on October 7, 1996, when American food company Odwalla produced a batch of unpasteurized apple juice using blemished fruit contaminated with the E. coli bacterium, which ultimately killed a 16-month-old girl and sickened 70 people in California, Colorado, Washington state, and British Columbia, of whom 25 were hospitalized and 14 developed hemolytic uremic syndrome. Odwalla made and marketed unpasteurized fruit juices for the health segment of the juice market.
Listeria virus P100 is a virus of the family Herelleviridae, genus Pecentumvirus.
Food safety in Australia concerns the production, distribution, preparation, and storage of food in Australia to prevent foodborne illness, also known as food safety. Food Standards Australia New Zealand is responsible for developing food standards for Australia and New Zealand.
The 2017–2018 South African listeriosis outbreak, also known as Listeriosis Histeriosis, was a widespread outbreak of Listeria monocytogenes food poisoning that resulted from contaminated processed meats produced by Enterprise Foods, a subsidiary of Tiger Brands, in Polokwane. There were 1,060 confirmed cases of listeriosis during the outbreak, and about 216 deaths. It is the world's deadliest listeriosis outbreak.
Food safety in the United States relates to the processing, packaging, and storage of food in a way that prevents food-borne illness within the United States. The beginning of regulation on food safety in the United States started in the early 1900s, when several outbreaks sparked the need for litigation managing food in the food industry. Over the next few decades, the United States created several government agencies in an effort to better understand contaminants in food and to regulate these impurities. Many laws regarding food safety in the United States have been created and amended since the beginning of the 1900s. Food makers and their products are inspected and regulated by the Food and Drug Administration and the Department of Agriculture.
Milk borne diseases are any diseases caused by consumption of milk or dairy products infected or contaminated by pathogens. Milk borne diseases are one of the recurrent foodborne illnesses—between 1993 and 2012 over 120 outbreaks related to raw milk were recorded in the US with approximately 1,900 illnesses and 140 hospitalisations. With rich nutrients essential for growth and development such as proteins, lipids, carbohydrates, and vitamins in milk, pathogenic microorganisms are well nourished and are capable of rapid cell division and extensive population growth in this favourable environment. Common pathogens include bacteria, viruses, fungi, and parasites and among them, bacterial infection is the leading cause of milk borne diseases.
The 2008–2009 Chilelisteriosis outbreak was an epidemic outbreak of listeriosis in that country, caused by the species Listeria monocytogenes, which spread mainly through foods of animal origin, such as cecina, sausages, cheese and other dairy products. As of August 2009, 164 cases had been recorded, with a total of 16 deaths, among whom different strains of the bacterium were detected.
The 2024 United States listeriosis outbreak is an ongoing widespread outbreak of listeriosis, connected to deli meats produced by Boar's Head Provision Company at a plant in Greensville County, Virginia, near the town of Jarratt. The outbreak was first reported in July 2024, although the first cases were later discovered to have been in May 2024. As of September 25, 2024, at least 10 people in the United States have died and 59 people have been hospitalized from the outbreak.

Between January 1, and June 14, 1985, 86 cases of Listeria monocytogenes infection were identified in Los Angeles and Orange Counties, California. Fifty-eight of the cases were among mother-infant pairs. Twenty-nine deaths have occurred: eight neonatal deaths, 13 stillbirths, and eight non-neonatal deaths. An increased occurrence of listeriosis was first noted at the Los Angeles County-University of Southern California Medical Center; all cases were in pregnant Hispanics, and all appeared to be community-acquired. A systematic review of laboratory records at hospitals in Los Angeles and Orange County identified additional cases throughout the area.
At least 13 people in eight states have died after eating cantaloupe contaminated with listeria, in the deadliest outbreak of food-borne illness in the United States in more than a decade, public health officials said on Tuesday. ... The outbreak appeared to be the third worst in the United States attributed to any form of food-borne illness, in terms of the number of deaths, since the C.D.C. began regularly tracking such outbreaks in the early 1970s. The deadliest outbreak in the United States since then occurred in 1985, when a wave of listeria illness, linked to Mexican-style fresh cheese, swept through California. A federal database says 52 deaths were attributed to the outbreak, but news reports at the time put the number as high as 84. The second-deadliest outbreak was in 1998 and 1999, when there were at least 14 deaths and four miscarriages or stillbirths in a listeria outbreak linked to hot dogs and delicatessen meats. Some sources put the death toll in that outbreak as high as 21. ...
Summer 1985: In Southern California, the largest number of food poisoning deaths recorded in recent U.S. history is traced to Mexican-style soft chesse. Of the 142 reported cases, there were 47 deaths, including 19 stillbirths and 10 infant deaths. The killer -- Listeria monocytogenes.
A total of 146 persons infected with any of the four outbreak-associated strains of Listeria monocytogenes were reported to CDC from 28 states.

Prewashed, bagged spinach from Dole was contaminated with E. coli. At least 205 consumers fell ill; three died. Investigators traced the strain back to the field in California and said that in this instance, washing could not have removed the bacteria.
The Pennsylvania Department of Health and CDC are investigating an outbreak of hepatitis A outbreak among patrons of a restaurant (Restaurant A) in Monaca, Pennsylvania. As of November 20, approximately 555 persons with hepatitis A have been identified, including at least 13 Restaurant A food service workers and 75 residents of six other states who dined at Restaurant A. Three persons have died. Preliminary sequence analysis of a 340 nucleotide region of viral RNA obtained from three patrons who had hepatitis A indicated that all three virus sequences were identical. Preliminary analysis of a case-control study implicated green onions as the source of the outbreak. ...

The incident did not take a toll only on the company, however. Bon Vivant did not have adequate records and controls of production lots and distribution in order to trace the products quickly. The company also did not have the finances or manpower necessary to run a successful recall program. As a result, the FDA had to seize all the Bon Vivant soup throughout the country, more than a million cans in all. FDA said the seizure occupied 125 man years of FDA time, enough for 2,000 ordinary factory inspections for preventive purposes. After some squabbling in the courts, where the owner of the company sought to recover the seized cans for resale under the company's new name, "Moore & Co.," the soup was eventually incinerated, at the cost of nearly $150,000 to the federal government. As for Moore & Co., it appears the resurrection of the company was short-lived.
Representatives of juice maker Odwalla Inc. agreed in a Fresno courtroom Thursday to pay a record $1.5 million criminal penalty for the 1996 E. coli outbreak that killed a Colorado girl and sickened at least 66 other people. The Half Moon Bay company admitted to 16 misdemeanor charges as part of a plea agreement stemming from the outbreak traced to contaminated apple juice made at the firm's plant in Dinuba.
Interviews with former Odwalla managers and company documents show that in the weeks before the outbreak, Odwalla began relaxing its standards on accepting blemished fruit and reining in the authority of its own safety officials, culminating in tense, dramatic moments on the morning of Oct. 7, 1996, the day the contaminated juice was pressed. ...
Mr Walters said one vacuum-packing machine was "wrongly used" for both raw and cooked meats. "It was not uncommon for juices from raw meat to get into the vacpacker. "There was blood on the trays and workers were having to wipe it off while they were packing cooked meat. "One employee said he was told by Tudor not to use the vacpacker for cooked meat whenever food inspectors were visiting."
Ten people were lab-confirmed victims of the outbreak. All required hospitalization. One person, a 37-year-old father of two, died. Nine of the victims had to spend time in intensive care units. Seven of the ICU patients had to be placed on ventilators because the botulism poisoning paralyzed muscles that are used for breathing. ...
