McDonald's E. coli outbreak cases under investigation in New Mexico
ALBUQUERQUE, N.M. – Across the nation, and in New Mexico, people are sick with E. coli tied to McDonald’s quarter pounders.
At least five New Mexicans are recovering from the E. coli outbreak. KOB 4 spoke with state health officials about the concerns here, and what symptoms should be on your radar.
“They may have blood in their stool, may become dehydrated and may have pretty severe vomiting. Normally this starts two to three days after exposure. Most people, it lasts five to seven days without medication. Most people recover, but certain people with other medical conditions are at a higher risk,” said Jose Acosta, director of the Division of Public Health at the New Mexico Department of Health.
Acosta says it is very important older people and children get to the hospital right away if they are experiencing these symptoms.
He says at risk populations can experience the most complications. They are also working with the CDC to make sure cases stay up to date.
“We track visits to the emergency room, whether it be related to the flu or related to COVID. This is something we track and identify and report it, and then we investigate it,” said Acosta.
KOB 4 went to some local McDonald’s Wednesday and spoke to some people who were thinking of grabbing a bite. They say they’re relieved to know McDonald’s has taken quarter pounders off the menu for now.
But many of them say this is definitely making them think twice about how much fast food they eat.
“Yeah, definitely, it makes me think more than twice about that. It is definitely gross. I used to eat like fast food a lot, and then I mean I have heard things about that, so I have just started cooking from home.”
What’s the timeline investigators are narrowing down for when people ate the infected burgers? The CDC reports the illnesses started between Sept. 27 and Oct. 11, and symptoms usually start a few days after you contract the bacteria.
NBC News reported earlier Wednesday the famous diced onions on the burgers could be the culprit. But investigators are still looking into the origin of the bacteria.
Besides monitoring symptoms and going to the doctor, is there anything else folks should do if they’re worried they’ve contracted E. coli?
The Department of Health has a 24/7 hotline at 1-833-SWNURSE (1-833-796-8773) to get connected to a nurse in case you want to run your situation by them.

Monday’s Top Stories
Monday’s Five Facts
[1] ABQ City Councilor aims to bolster protections for renters amid unseasonable warmth – Albuquerque city councilor is looking to make sure city landlords are not only providing cooling systems, but also ensuring they actually work when they’re needed. City Councilor Tammy Fiebelkorn spearheaded an ordinance in December of 2024, requiring all Albuquerque rental properties to have a cooling system. Now, Fiebelkorn is taking it a step further, hoping to establish cooling system performance requirements. The ordinance is expected to be voted on in final action at Monday’s city council meeting.
[2] Rio Grande showing dry spots in Valencia County amid record-low snowpack – Portions of the Rio Grande are now seeing dry spots earlier than expected. Officials say the timing is not normal. In Valencia County, parts of the river are already running dry. Near the river crossing in Los Lunas, the river has open pockets. Further south, it is being reported as dry as well. There is a slight positive outlook for the monsoon season, with forecasters and officials predicting a strong season in the Middle Rio Grande Valley.
[3] Very spotty rainfall, warmer, & mostly calm week – Warmer weather will continue building in across the state throughout the upcoming week. A few isolated rain chances will return Monday in parts of New Mexico, but some of that rain may evaporate before reaching the ground. Temperatures will continue to increase through the middle of the week.
[4] NM representatives celebrate grand opening of new office with open house – A new state legislative office made its debut for representatives Eleanor Chavez and Yanira Gurrola. The new location is just one of the handful of new legislative offices now open across the state. They hosted a grand opening for the building that was open to the public. Representative Gurrola says it’s just one step towards modernizing the state’s legislature. The new office will allow residents to stay more connected to each representative.
[5] New Mexico Motorfest 2026 takes place in celebration of Route 66 Centennial – Another Route 66 celebration took place over the weekend and this one was all about cars. The New Mexico Motorfest happened at the Expo New Mexico racetrack. Over 300 vehicles from classic hot rods to lifted trucks were featured at the event. Some of the proceeds went to New Mexico veterans.
