Yum! Brands and Burger King removed onions from some of their locations as the restaurant industry investigates an E. coli outbreak first traced to McDonald’s Corp.

Yum withdrew fresh onions from some Taco Bell, Pizza Hut and KFC locations “out of an abundance of caution,” the company said Thursday in a statement without disclosing which stores and regions were affected or naming suppliers.

“We will continue following supplier and regulatory guidance to ensure the ongoing safety and quality of our food,” the company said.

Burger King said Thursday that it gets some of its onions from a Colorado facility run by Taylor Farms, which supplied the McDonald’s restaurants that have been impacted by the outbreak.

Taylor Farms issued a recall of some its yellow onion batches despite finding no traces of E. coli as of Wednesday. Restaurant distributors U.S. Foods Holding Corp. and Sysco Corp. have also notified customers of the recall.

“Despite no contact from health authorities and no indications of illness, we proactively asked our 5% of restaurants who received whole onions distributed by this facility to dispose of them immediately two days ago and we are in the process of restocking them from other facilities,” Burger King said.

Fat Brands Inc., owner of restaurants including Johnny Rockets, said it pulled all of Taylor Farms’ fresh onion products.

The restaurant industry is on alert after the U.S. Centers for Disease Control and Prevention said Tuesday that an E. coli outbreak likely tied to preslivered onions served on McDonald’s Quarter Pounders sickened dozens of people in the U.S. and killed one. Burger King said it buys whole onions that are cut, peeled and sliced in its restaurants.

McDonald’s pulled the popular product from about 20% of its more than 13,000 U.S. restaurants, and it’s working with health authorities to confirm the source.

Tesla soars to best day in over a decade after forecast reported

Tesla’s shares surged the most in more than 11 years after the carmaker reported surprisingly strong earnings and forecast as much as 30% growth in vehicle sales next year.

Third-quarter results were buoyed by Tesla turning a corner with the Cybertruck, which generated profit for the first time. Lower material costs, an expanding energy business and sales of regulatory credits to automakers that need help complying with emissions limits also contributed to Tesla’s best quarterly earnings in more than a year.

CEO Elon Musk offered an upbeat outlook for 2025, citing the rollout of more affordable models that Tesla has yet to identify. “Something like 20% to 30% growth next year is my best guess,” he said on a webcast.

Tesla’s shares jumped 22% Thursday in New York, the biggest gain since May 2013. That helped add tens of billions of dollars to Musk’s net worth and sent the stock into positive territory for the year, erasing a slump in the weeks since the CEO unveiled self-driving taxi and van prototypes.

CVS workers reach tentative contract agreement

The unions representing more than 7,000 CVS workers in Southern California have reached a tentative agreement on a contract after workers went on strike over the weekend demanding better pay and staffing and more affordable health care.

The walkout, which affected four stores in Los Angeles and three in Orange County, began Oct. 18 and continued through that weekend. The union filed unfair labor practice charges against the company over using intimidation tactics and preventing workers from speaking to their union representatives.

A bargaining session was scheduled for Wednesday to negotiate the details of a contract that expired in June.

Union members will now have an opportunity to review and vote on the contract that the committee “unanimously” recommends for approval.

Workers have said that they cannot afford the cost of the insurance CVS offers. They also say stores are understaffed to handle the extra demands of the flu season, and locked-up items on shelves further exacerbate the staffing shortage.
