Outbreak

The Food and Drug Administration (FDA) issued a public warning through its Coordinated Outbreak Response & Evaluation Network (CORE Network) about the E. coli outbreak on October 22. Their initial investigation noted 49 cases of E. coli throughout 10 U.S. states (Colorado, Kansas, Utah, Wyoming, and portions of Idaho, Iowa, Missouri, Montana, Nebraska, Nevada, New Mexico, and Oklahoma). The Centers for Disease Control and Prevention (CDC) at the time did not confirm the origin, but the government agency suspected it was either slivered onions or beef patties. [3] [4] An update to the investigation was published on October 25 with 26 new cases, 12 new hospitalizations, and 3 new U.S. states (Oregon, Washington, and Utah). [5]

On October 22, McDonald's stores in the affected states temporarily removed the Quarter Pounder from the menu or stopped serving it with the specific slivered onions and beef patties. [3] [6] The Colorado Department of Agriculture (CDA) laboratories analyzed subsamples from all the lots of McDonald's brand fresh and frozen beef patties collected from various McDonald's locations in Colorado and found them to be negative for E. coli.

On October 23, a man who fell ill after eating a sandwich at the fast food chain's Greeley, Colorado location filed a lawsuit against McDonald's over an E. coli outbreak linked to its Quarter Pounder burgers. The lawsuit is one of the first in the case. [7]

A second update on the investigation was published on October 30, stating that epidemiologic and traceback information shows that fresh, slivered onions were the likely source of illness in this outbreak. [3] [8] The Food Safety and Inspection Service (FSIS) performed a traceback of beef patties served on Quarter Pounders at McDonald's, and evidence did not point to ground beef as the likely source of contamination. [3] The Food and Drug Administration is looking into a Washington onion "grower of interest". [9]

A third update was published on November 13, adding 14 new cases, 7 new hospitalizations, and North Carolina to the affected states. [1] The FDA tested recalled onions in which one sample tested positive for non-O157:H7 Shiga toxin-producing E. coli. The E. coli found was not the outbreak strain. A fourth and final update was published on December 3, with no additional cases. The CDC declared the outbreak over. [4] [10]

Infection

Escherichia coli O157:H7 is a serotype of the bacterial species Escherichia coli and is one of the Shiga-like toxin–producing types of E. coli. It is a cause of disease, typically foodborne illness, through consumption of contaminated and raw food, including raw milk and undercooked ground beef. [11] [12]

Responses

On October 25, Taylor Farms, the supplier of the slivered onions to the affected stores, initiated a voluntary recall on yellow onions. [5] [6] While there were growers of interest that supplied Taylor Farms, FDA has not been able to implicate the specific grower. [13]

On December 3, 2024, the CDC declared the outbreak was "over," and the FDA announced they had closed their investigation. [10]

<i>Escherichia coli</i> O157:H7 Serotype of the bacteria Escherichia coli

Escherichia coli O157:H7 is a serotype of the bacterial species Escherichia coli and is one of the Shiga-like toxin–producing types of E. coli. It is a cause of disease, typically foodborne illness, through consumption of contaminated and raw food, including raw milk and undercooked ground beef. Infection with this type of pathogenic bacteria may lead to hemorrhagic diarrhea, and to kidney failure; these have been reported to cause the deaths of children younger than five years of age, of elderly patients, and of patients whose immune systems are otherwise compromised.

<span class="mw-page-title-main">Coliform bacteria</span> Group of bacterial species

Coliform bacteria are defined as either motile or non-motile Gram-negative non-spore forming bacilli that possess β-galactosidase to produce acids and gases under their optimal growth temperature of 35–37 °C. They can be aerobes or facultative aerobes, and are a commonly used indicator of low sanitary quality of foods, milk, and water. Coliforms can be found in the aquatic environment, in soil and on vegetation; they are universally present in large numbers in the feces of warm-blooded animals as they are known to inhabit the gastrointestinal system. While coliform bacteria are not normally the cause of serious illness, they are easy to culture, and their presence is used to infer that other pathogenic organisms of fecal origin may be present in a sample, or that said sample is not safe to consume. Such pathogens include disease-causing bacteria, viruses, or protozoa and many multicellular parasites. Every drinking water source must be tested for the presence of these total coliform bacteria.

Romaine or cos lettuce is a variety of lettuce that grows in a tall head of sturdy dark green leaves with firm ribs down their centers. Unlike most lettuces, it is tolerant of heat. In North America, romaine is often sold as whole heads or as "hearts" that have had the outer leaves removed and are often packaged together.

<span class="mw-page-title-main">Quarter Pounder</span> Hamburger sold by McDonalds

The Quarter Pounder is a hamburger sold by international fast food chain McDonald's, so named for containing a patty with a precooked weight of four ounces (113.4 g), or one quarter of a pound. It was introduced in 1971. In 2013, the Quarter Pounder was expanded to represent a whole line of hamburgers that replaced the company's discontinued Angus hamburger. In 2015, McDonald's increased the precooked weight to 4.25 oz (120 g).

The 2006 North American E. coli outbreak was an Escherichia coli O157:H7 outbreak from prepackaged spinach. The outbreak occurred in September 2006, and its origin was an Angus cattle ranch that had leased land to a spinach grower. At least 276 consumer illnesses and 3 deaths have been attributed as a result from the outbreak.

Escherichia coli O121 is a pathogenic serotype of Escherichia coli, associated with Shiga toxin, intestinal bleeding, and hemolytic-uremic syndrome (HUS). HUS, if left untreated, can lead to kidney failure.

Topps Meat Company was a privately owned family company founded in 1940 by Benjamin Sachs in Manhattan, New York. The company later relocated to Elizabeth, New Jersey. The company produced and distributed frozen ground beef patties and other meat products processed at its 3,000-square-foot (280 m2) plant in Elizabeth and posted about $8.8 million a year in sales, according to information reported by Dun & Bradstreet. In 2003, the company was purchased by Strategic Investment and Holdings, an investment firm based in Buffalo, New York and by 2007 it was "one of the country’s largest manufacturers of frozen hamburgers." In 2007 the company ceased operations following Escherichia coli O157:H7 contamination of products and the ensuing recall.

XL Foods Inc. is a Canadian meat packing company. The company is a subsidiary of Nilsson Brothers Inc. based in Edmonton, Alberta. From 2009 until 2013, XL Foods' Lakeside Packers Division was located just west of Brooks, Alberta, in Newell County. This facility was the second largest beef-processing operation in Canada. During this period the company was by far the largest employer in Brooks, employing more than 2,200 people in 2012.

Raw meat generally refers to any type of uncooked muscle tissue of an animal used for food. In the meat production industry, the term ‘meat’ refers specifically to mammalian flesh, while the words ‘poultry’ and ‘seafood’ are used to differentiate between the tissue of birds and aquatic creatures.

2011 Germany <i>E. coli</i> O104:H4 outbreak Foodborne illness outbreak

A novel strain of Escherichia coli O104:H4 bacteria caused a serious outbreak of foodborne illness focused in northern Germany in May through June 2011. The illness was characterized by bloody diarrhea, with a high frequency of serious complications, including hemolytic–uremic syndrome (HUS), a condition that requires urgent treatment. The outbreak was originally thought to have been caused by an enterohemorrhagic (EHEC) strain of E. coli, but it was later shown to have been caused by an enteroaggregative E. coli (EAEC) strain that had acquired the genes to produce Shiga toxins, present in organic fenugreek sprouts.

Pathogenic <i>Escherichia coli</i> Strains of E. coli that can cause disease

Escherichia coli is a gram-negative, rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms (endotherms). Most E. coli strains are harmless, but pathogenic varieties cause serious food poisoning, septic shock, meningitis, or urinary tract infections in humans. Unlike normal flora E. coli, the pathogenic varieties produce toxins and other virulence factors that enable them to reside in parts of the body normally not inhabited by E. coli, and to damage host cells. These pathogenic traits are encoded by virulence genes carried only by the pathogens.

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.

In 2006, there were several outbreaks of foodborne illness from spinach and lettuce contaminated by E. coli O157:H7.

1992–1993 Jack in the Box <i>E. coli</i> outbreak Fast food disease outbreak

The 1992–1993 Jack in the Box E. coli outbreak occurred when the Escherichia coli O157:H7 bacterium killed four children and infected 732 people across four US states. The outbreak involved 73 Jack in the Box restaurants in California, Idaho, Washington, and Nevada, and has been described as "far and away the most infamous food poison outbreak in contemporary history." The majority of the affected were under 10 years old. Four children died and 178 others were left with permanent injury including kidney and brain damage.

Driven by fresh-market use, the consumption of spinach has been on the rise in the United States. Per capita use of fresh-market spinach averaged 1 kilogram (2.2 lb) during 2004–2006, the highest since the mid-1940s. The fresh market now accounts for about three-fourths of all US spinach consumed. Much of the growth over the past decade has been due to sales of triple-washed, cello-packed spinach and, more recently, baby spinach. These packaged products have been one of the fastest-growing segments of the packaged salad industry.

Ground meat, called mince or minced meat outside North America, is meat finely chopped by a meat grinder or a chopping knife. A common type of ground meat is ground beef, but many other types of meats are prepared in a similar fashion, including pork, veal, lamb, goat meat, and poultry.

The 2015 United States E. coli outbreak was an incident in the United States involving the spread of Escherichia coli O157:H7 through contaminated celery which was consumed in chicken salad at various large retailers. A product recall covering more than one dozen states and over 155,000 products has taken place as a result of the incident.

<span class="mw-page-title-main">Food safety in the United States</span>

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.
