    Fast Facts

    Cases: 49
    Hospitalizations: 10
    Deaths: 1
    States: 10

    Situation summary

    CDC, FDA, USDA FSIS, and public health officials in multiple states are investigating an outbreak of E. coli O157:H7 infections. Most people in this outbreak are reporting eating the Quarter Pounder hamburger at McDonald’s before becoming sick. It is not yet known which specific food ingredient is contaminated.

    McDonald’s is collaborating with investigation partners to determine what food ingredient in Quarter Pounders is making people sick. McDonald’s stopped using fresh slivered onions and quarter pound beef patties in several states while the investigation is ongoing to identify the ingredient causing illness.
    Contaminated food

    McDonald's Quarter Pounder hamburgers are making people sick, with most illnesses in Colorado and Nebraska.

    Quarter Pounder hamburgers will not be available temporarily in some states.
    Investigators are working to confirm which ingredient in these hamburgers is making people sick and if it went to other restaurants or stores.
    McDonald's reported to CDC that it has stopped using fresh slivered onions and quarter pound beef patties in several states. McDonald's is proactively making these changes while investigators work to confirm the contaminated ingredient. Quarter pound beef patties are only used on Quarter Pounders. Fresh slivered onions are primarily used on Quarter Pounder hamburgers and not other menu items.

    What you should do

    McDonald’s has stopped using fresh slivered onions and quarter pound beef patties in several states to protect their customers while a source of illness is confirmed.

    Call your healthcare provider if you ate a McDonald’s Quarter Pounder hamburger and have severe E. coli symptoms:

    Diarrhea and a fever higher than 102°F
    Diarrhea for more than 3 days that is not improving
    Bloody diarrhea
    So much vomiting that you cannot keep liquids down
    Signs of dehydration, such as:
    Not peeing much
    Dry mouth and throat
    Feeling dizzy when standing up

    Symptoms of E. coli

    Most people infected with Shiga toxin-producing E. coli experience severe stomach cramps, diarrhea (often bloody), and vomiting.
    Symptoms usually start 3 to 4 days after swallowing the bacteria.
    Most people recover without treatment after 5 to 7 days.
    Some people may develop serious kidney problems (hemolytic uremic syndrome, also called HUS) and would need to be hospitalized.

    Outbreak Investigation of E. coli O157:H7: McDonald’s Quarter Pounders (October 2024)

    Linked to McDonald’s Quarter Pounders served in certain states. Investigators are working to confirm the source of the outbreak.

    Content current as of:10/22/2024
    ​...
    Product


    A specific ingredient has not yet been confirmed as the source of the outbreak, but most sick people report eating McDonald’s Quarter Pounder burgers. Investigators are working to determine if the slivered onions or beef patties on Quarter Pounder burgers are the likely source of contamination. McDonald’s has temporarily stopped using Quarter Pounder slivered onions and beef patties in affected states. Diced onions and other types of beef patties used at McDonald’s have not been implicated in this outbreak.

    Symptoms of E. coli

    Symptoms begin anywhere from a few days after consuming contaminated food or up to nine days later. Symptoms include severe stomach cramps, diarrhea, fever, nausea, and/or vomiting. Some infections can cause severe bloody diarrhea and lead to life-threatening conditions, such as a type of kidney failure called hemolytic uremic syndrome (HUS), or the development of high blood pressure, chronic kidney disease, and neurologic problems.

    Stores Affected

    McDonald’s stores in Colorado, Kansas, Utah, Wyoming, and portions of Idaho, Iowa, Missouri, Montana, Nebraska, Nevada, New Mexico, and Oklahoma have temporarily stopped using Quarter Pounder slivered onions and beef patties.

    Status

    Ongoing; updates will be provided as they become available.

    Recommendation
    • Consumers who have already eaten at McDonald’s and have symptoms of E. coli infection should contact their health care provider to report their symptoms and receive care immediately.
    • McDonald’s stores in affected states have temporarily stopped using Quarter Pounder slivered onions and beef patties. Diced onions and other types of beef patties used at McDonald’s have not been implicated in this outbreak.
    Current Update

    October 22, 2024

    The FDA, U.S. Department of Agriculture (USDA) Food Safety and Inspection Service (FSIS), and Centers for Disease Control and Prevention (CDC), in collaboration with state and local partners, are investigating illnesses in a multistate outbreak of E. coli O157:H7 infections. A specific ingredient has not yet been confirmed as the source of the outbreak, but most sick people report eating McDonald’s Quarter Pounder burger varieties.

    Investigators are working to determine if the slivered onions or beef patties on Quarter Pounder burgers are the likely source of this outbreak.

    Preliminary traceback and distribution information reviewed by FDA shows that slivered onions served on Quarter Pounders are a likely source of contamination. FDA is working quickly to confirm that these onions are a source of this outbreak and to determine if these onions were served or sold at other businesses. McDonald’s has temporarily stopped using this type of onion in these states. Diced onions used at McDonald’s are not implicated in this outbreak.

    FSIS is conducting traceback on hamburger patties served at McDonald’s in affected states to determine if ground beef is a source of illness. McDonald’s has also temporarily stopped selling Quarter Pounder beef patties in affected states, while the investigation is ongoing to determine the source of the outbreak.

    This advisory will be updated as additional information becomes available.

      The person who died in Colorado and whose death is tied to a multi-state McDonald's E. coli outbreak lived in Mesa County. That's according to Mesa County Public Health, which has not released the identity of the deceased person. According to the Colorado Department of Public Health and Environment, it was a man who was in his older years.​

      Colorado is the only state where a death has been reported, and it is the state with the most cases of people getting sick from E. coli food poisoning linked in McDonald's Quarter Pounder hamburgers.

      "While the specific source of contamination is still under investigation, early information from the Food and Drug Administration indicates the onions on McDonald's Quarter Pounders may be a source of this outbreak," Mesa County Public Health wrote in a news release. "Fresh-slivered onions are primarily used on Quarter Pounder hamburgers and not other menu items. USDA is also looking into the beef patties on the Quarter Pounder hamburgers."

      The CDPHE says there have been 26 cases reported in nine different Colorado counties, and they are located in several different parts of the state:

      Arapahoe County
      Chaffee County
      El Paso County
      Gunnison County
      Larimer County
      Mesa County
      Routt County
      Teller County
      Weld County ...

      Mesa County Public Health officials say the person who died in Colorado and whose death is tied to a multi-state McDonald's E. coli outbreak lived in Mesa County.

        McDonald's takes Quarter Pounder off the menu at 1 in 5 restaurants due to E. coli outbreak

        ​Updated on: October 23, 2024 / 4:35 PM EDT / CBS News​
        By Kate Gibson

        McDonald's has stopped selling Quarter Pounder hamburgers at about one-fifth of its U.S. restaurants as federal health officials investigate an outbreak of E. coli that has sickened nearly 50 people in 10 states, killing one.

        The fast-food chain sold about 1 million Quarter Pounders in the timeframe that the illnesses occurred, a McDonald's spokesperson said Wednesday. The company said it believes more people would have been sickened if the contamination stemmed from the patties themselves, adding that onions used on the burgers may be the culprit. ...

        What may have caused the E. coli outbreak?

        Cesar Piña, the company's North America chief supply chain officer, said in a statement on Tuesday that the company's initial investigation suggests that some of the E. coli illnesses might be linked to slivered onions used in the Quarter Pounder. ...

          Taylor Farms, a California-based produce grower, issued a recall for its yellow onions, a day after sliced onions were named as the possible cause of an E.coli outbreak linked to McDonald’s that has killed one person and sickened 26 people across Colorado.

          It’s unclear if the recall is linked to the problems at the fast food burger chain, but the notice has prompted other businesses to pull onions from menus as a precaution, including Illegal Pete’s, a Colorado-based chain of fast-casual burrito restaurants.

          Managers at Illegal Pete’s, a fast-casual burrito restaurant chain, were told to dispose yellow onions, a day after an E. coli outbreak was linked to McDonald's Quarter Pounders

            McDonald's says beef unlikely but not ruled out as potential source of E. coli outbreak
            ...
            By Breck Dumas FOXBusiness
            ...
            McDonald's North America chief supply chain officer Cesar Piña said in an internal statement following the CDC's announcement that the company is "taking swift and decisive action" to address the outbreak, and reported, "The initial findings from the investigation indicate that a subset of illnesses may be linked to slivered onions used in the Quarter Pounder and sourced by a single supplier that serves three distribution centers."
            ...
            McDonald's spokespeople said Wednesday that the CDC informed the company of the outbreak last week, and the company is working with the agencies involved to determine whether beef or onions — the two ingredients in the sandwich that could be carriers for E. coli — are the cause.
            ...
            But if beef is the source, it would mean multiple McDonald's restaurants did not cook the patties to the standard 175 degrees required by the chain, given that E. coli is killed at 160 degrees.

            McDonald's is also looking closely at the fresh slivered onions used as a topping because they are a raw ingredient that came from a single source. However, if the onions are determined to be the cause, it would be the first time onions have been the source of an outbreak of this particular strain of E. coli — E. coli O157:H7.
            ...

            McDonald's and multiple government agencies are still investigating the source of an E. coli outbreak linked to Quarter Pounders after 49 people reported getting sick and one died.

              Fast-food chains hold the onions after McDonald's E. coli outbreak

              LONGMONT, Colorado, Oct 24 (Reuters) - U.S. fast-food chains were pulling fresh onions out of their menu items on Thursday after the vegetable was named as the likely source of an E. coli outbreak at McDonald's (MCD.N), opens new tab restaurants that has sickened 49 people and killed one.

              Restaurant Brands International (QSR.TO), opens new tab, parent of McDonald's rival Burger King, and Yum Brands (YUM.N), opens new tab said they were removing fresh onions from menu items. Roughly 5% of Burger King locations have removed onions from the menu, a Burger King spokesperson said in a statement.

              McDonald's said on Thursday that Taylor Farms was the supplier of the sliced onions that have been removed. Taylor Farms did not immediately respond to a request for comment. The company has recalled several batches of yellow onions produced in a Colorado facility, according to a recall memo on Wednesday by US Foods (USFD.N), opens new tab, one of the largest U.S. suppliers of food service operations.

                Investigation Update: E. coli Outbreak, McDonald's Quarter Pounders - October 22, 2024

                KEY POINTS
                This is a fast-moving outbreak investigation. Most sick people are reporting eating Quarter Pounder hamburgers from McDonald’s and investigators are working quickly to confirm which food ingredient is contaminated. McDonald’s has pulled ingredients for these burgers, and they won’t be available for sale in some states.

                Notice Locations Timeline

                October 25, 2024

                CDC, public health and regulatory officials in several states, the U.S. Food and Drug Administration (FDA), and the U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA-FSIS) are collecting different types of data to investigate a multistate outbreak of E. coli O157:H7 infections.

                Epidemiologic data show that Quarter Pounder hamburgers served at McDonald’s are contaminated with E. coli and are making people sick. Early information from FDA indicates onions may be a source of this outbreak. Investigators from all agencies are working quickly to determine the contaminated ingredient.

                Epidemiologic data

                As of October 24, 75 people infected with the outbreak strain of E. coli O157:H7 have been reported from 13 states. Illnesses started on dates ranging from Sept 27, 2024, to October 10, 2024. Of 61 people with information available, 22 have been hospitalized, and 2 people developed hemolytic uremic syndrome, a serious condition that can cause kidney failure. One death has been reported from an older adult in Colorado. This person is not one of those who developed HUS.

                The true number of sick people in this outbreak is likely much higher than the number reported, and the outbreak may not be limited to the states with known illnesses. This is because many people recover without medical care and are not tested for E. coli. In addition, recent illnesses may not yet be reported as it usually takes 3 to 4 weeks to determine if a sick person is part of an outbreak.

                Public health officials collect many different types of information from sick people, including their age, race, ethnicity, other demographics, and the foods they ate in the week before they got sick. This information provides clues to help investigators identify the source of the outbreak.

                The table below has information about sick people in this outbreak (“n” is the number of people with information available for each demographic).

                Demographics Information

                Age
                (n=74)
                Range from 13 to 88 years
                Median age of 29

                Sex
                (n=75)
                40% female
                60% male

                Race
                (n=59)
                95% White
                3% African American/Black
                0% Native American or Alaska Native
                0% Asian
                0% Native Hawaiian or other Pacific Islander
                2% reported more than one race

                Ethnicity
                (n=55)
                91% non-Hispanic
                9% Hispanic

                State and local public health officials are interviewing people about the foods they ate in the week before they got sick. Of the 42 people interviewed, all 42 (100%) report eating at McDonald's, and 39 people report eating a beef hamburger. Of 36 people who remember the specific beef hamburger they ate at McDonald's, 31 (86%) report eating a Quarter Pounder hamburger. Some people in this outbreak reported traveling to other states before their illness started. At least three people ate at McDonald's during their travel.

                Traceback Information

                Investigators are working to determine if the slivered onions or beef patties in Quarter Pounder burgers are the specific source of this outbreak.

                Preliminary traceback and distribution information reviewed by FDA shows that slivered onions served on Quarter Pounders are a likely source of contamination. FDA is working quickly to confirm that these onions are a source of this outbreak and to determine if these onions were served or sold at other businesses.

                Taylor Farms, the supplier of slivered onions for affected McDonald’s locations initiated a recall of yellow onions. Customers were contacted directly and asked to remove products. FDA is working closely with the implicated firms and will continue to provide updates including any additional recalls that might be needed for businesses who received recalled onions.


                FSIS is conducting traceback on hamburger patties served at McDonald’s to determine if ground beef is a source of illness.

                Public health actions

                McDonalds has stopped using fresh slivered onions and quarter pound beef patties in several states to protect their customers while a source of illness is confirmed. Quarter Pounders will not be available for sale temporarily in some states. Call your healthcare provider if you ate a McDonald’s Quarter Pounder hamburger and have severe E. coli symptoms.

                  Beef Patties Test Negative for E. Coli at CDA Lab

                  Sunday, October 27, 2024

                  On Tuesday, October 22, the Colorado Department of Agriculture (CDA) laboratories received multiple lots of McDonald’s brand fresh and frozen beef patties collected from various Colorado McDonald’s locations associated with the ongoing E. Coli investigation.

                  The CDA Microbiology Laboratory analyzed dozens of subsamples from all the lots and all samples were found to be negative for E. coli. CDA has completed all beef testing and does not anticipate receiving further samples.

                  The federal investigation has focused on ground beef patties and onions. At this time, CDA also has no information suggesting onions grown in Colorado are linked to this outbreak.

                  The FDA is leading the traceback investigation of onions for this outbreak. For more information, please contact the FDA Office of Media Affairs at FDAOMA@FDA.HHS.GOV. USDA’s Food Safety and Inspection Service (FSIS) is the lead agency for meat in the U.S. and can be reached at FSISPress@usda.gov. The Colorado Department of Public Health and Environment is the lead Colorado agency on this incident response in Colorado. To reach CDPHE, please email hope.shuler@state.co.us.
                  Las hamburguesas de carne de res dieron negativo en la prueba de E. coli en el laboratorio del CDA


                  El martes 22 de octubre, los laboratorios del Departamento de Agricultura de Colorado (CDA) recibieron varios lotes de hamburguesas de carne fresca y congelada de la marca McDonald's recolectadas de varias ubicaciones de McDonald's de Colorado asociadas con la investigación en curso sobre E. coli.

                  El Laboratorio de Microbiología del CDA analizó docenas de submuestras de todos los lotes y se encontró que todas las muestras dieron negativo para E. coli. El CDA ha completado todas las pruebas de carne y no prevé recibir más muestras.

                  La investigación federal se ha centrado en las hamburguesas de carne molida y las cebollas. En este momento, el CDA tampoco tiene información que sugiera que las cebollas cultivadas en Colorado estén vinculadas a este brote.

                  La FDA está liderando la investigación de rastreo de cebollas para este brote. Para obtener más información, comuníquese con la Oficina de Asuntos de Prensa de la FDA en FDAOMA@FDA.HHS.GOV. USDA-APHIS es la agencia líder en materia de carne en los EE. UU. y se puede contactar en aphispress@usda.gov. El Departamento de Salud Pública y Medio Ambiente de Colorado es la agencia líder de Colorado en la respuesta a este incidente en Colorado.

                  Our commitment to food safety isn’t the responsibility of any one person, team, department, or leg of the stool.

                  Our commitment to food safety is everyone’s primary responsibility, and this week we’ve been reminded why.

                  First, I want to thank once again the health authorities with whom we’ve been partnering. They can count on McDonald’s continued close partnership in their vital work, now and well into the future.

                  As someone who has worked in food safety for two decades, it has been meaningful to see the strong partnership between McDonald’s and public health officials, including CDC, Colorado Department of Public Health and Environment, Colorado Department of Agriculture, USDA, FSIS, and FDA. 

                  It was especially important to all of us—across the entire System—when CDC noted that our proactive steps resulted in the risk to the public being “very low.”

                  This was also a reminder of how our values must guide us every single day: we put people first, and we do the right thing.

                  The issue appears to be contained to a particular ingredient and geography, and we remain very confident that any contaminated product related to this outbreak has been removed from our supply chain and is out of all McDonald’s restaurants.

                  That said, health officials have noted that with increased awareness, more people will seek medical attention and case counts will grow. This awareness is a good thing, as it can lead to people being vigilant and connecting with medical professionals.

                  As the CDC has shared, symptoms usually start 3 to 4 days after consuming contaminated food, and most people recover without treatment after 5 to 7 days. That said, it can take 3-4 weeks for public health agencies to confirm if an ill person is part of the outbreak. 

                  While we understand that slivered onions from this facility were distributed well beyond McDonald’s System to other quick service restaurants and food service providers, public health agencies’ interviews at this stage will likely focus on patients who note visiting McDonald’s. This could also account for more cases being linked to McDonald’s.

                  We are committed to making this right for any customers who have eaten at McDonald’s and suffered an illness as a result of the outbreak.

                  As Joe shared last week, we will continue to be guided by our principles while managing this situation and earning our customers’ trust:
                  • Continue to do the right thing
                  • Partner closely with health authorities and let science lead our decision making
                  • Take swift and decisive action
                  • Deploy the full breadth of our resources
                  • Continue to communicate quickly and transparently

                  With that, there are a few important updates that we’d like to share.
                  • Over the weekend, McDonald’s was informed that the Colorado Department of Agriculture has completed their testing, the results of which confirm that there was no detection of E. coli in the samples taken of Quarter Pounder beef patties from restaurants in this area. We’ve been informed there is no further testing planned for beef patties.
                  • Overlaying the CDC's Epidemiological data with our Supply Chain traceback data, we have ruled out Quarter Pounder patties as the source.
                  • Last week, out of an abundance of caution, we stopped distributing Quarter Pounder beef patties to the impacted area. Based on the above information, we are now confident in asking our beef suppliers to produce a new supply of fresh beef patties for the impacted areas. We will resume distribution of that fresh supply and the Quarter Pounder is expected to be available in all restaurants in the coming week. This will be on a rolling basis based on delivery and resupply operations. 
                  • The 900 restaurants that historically received slivered onions from Taylor Farms’ Colorado Springs facility will resume sales of Quarter Pounders without slivered onions. Those restaurants are in Colorado, Kansas, and Wyoming, as well as portions of Idaho, Iowa, Missouri, Montana, Nebraska, Nevada, New Mexico, Oklahoma, and Utah.
                  • A brief FAQ document is available here and for more information on McDonald’s Food Safety see here. 

                  The FDA is continuing its investigation into Taylor Farms’ Colorado Springs facility. As a reminder, McDonald’s removed slivered onions from this facility from our supply chain on October 22 and shared that we had decided to stop sourcing onions from Taylor Farms’ Colorado Springs facility indefinitely. Over the past few days, you’ve likely seen that additional food service providers and restaurant brands that received onions from this facility have moved to stop selling and/or recall onions.

                  I want to thank all of you for your support, for your efforts to promote public health, and for upholding our core values.

                    Investigation Update: E. coli Outbreak, Onions Served at McDonald's - October 30, 2024
                    Key points

                    Epidemiologic and traceback data show that fresh, slivered onions served at McDonald’s are the likely source of this outbreak. Onions were pulled from affected McDonald’s locations and Taylor Farms recalled yellow slivered onions sent to other food service operators.​

                    October 30, 2024

                    CDC, public health and regulatory officials in several states, the U.S. Food and Drug Administration (FDA), and the U.S. Department of Agriculture's Food Safety and Inspection Service (USDA-FSIS) are collecting different types of data to investigate a multistate outbreak of E. coli O157:H7infections.

                    Epidemiologic and traceback data show that fresh, slivered onions served at McDonald's were the likely source of this outbreak.
                    Epidemiologic data

                    As of October 30, 90 people infected with the outbreak strain of E. coli O157:H7 have been reported from 13 states. Illnesses started on dates ranging from Sept 27, 2024, to October 16, 2024. Of 83 people with information available, 27 have been hospitalized,and 2 people developed hemolytic uremic syndrome, a serious condition that can cause kidney failure. One death has been reported from an older adult in Colorado. This person is not one of those who developed HUS.

                    The true number of sick people in this outbreak is likely much higher than the number reported, and the outbreak may not be limited to the states with known illnesses. This is because many people recover without medical care and are not tested for E. coli. In addition, recent illnesses may not yet be reported as it usually takes 3 to 4 weeks to determine if a sick person is part of an outbreak.

                    Public health officials collect many different types of information from sick people, including their age, race, ethnicity, other demographics, and the foods they ate in the week before they got sick. This information provides clues to help investigators identify the source of the outbreak.

                    The table below has information about sick people in this outbreak ("n" is the number of people with information available for each demographic)....
