NEW YORK (AP) — It's OK to eat some romaine lettuce again, U.S. health officials said. Just check the label.The Food and Drug Administration narrowed its blanket warning from last week, when it said people shouldn't eat any type of romaine because of an E. coli outbreak. The agency said Monday that romaine recently harvested in Arizona, Florida, Mexico and California's Imperial Valley is OK to eat. It says romaine from those places wasn't yet shipping when the illnesses began.It says the tainted romaine appears to have come from the Central Coast region of California.The produce industry agreed to start putting harvest dates and regions on labels. For romaine that doesn't come in packaging, grocers and retailers are being asked to post the information by the register.The FDA warned Americans not to eat romaine that isn't labeled with that information, and it said it had commitments from the industry that such labeling will become standard for romaine. It also noted hydroponically grown romaine and romaine grown in greenhouses isn't implicated in the outbreak.The labeling arrangement was worked out as the produce industry called on the FDA to quickly narrow the scope of its warning so it wouldn't have to waste freshly harvested romaine. An industry group said people can expect to start seeing labels as early as this week. It noted the labels are voluntary, and that it will monitor whether to expand the measure to other leafy greens and produce.Robert Whitaker, chief science officer of the Produce Marketing Association, said labeling for romaine could help limit the scope of future alerts and rebuild public trust after other outbreaks."Romaine as a category has had a year that's been unfortunate," Whitaker said.The FDA still hasn't identified a source of contamination in the latest outbreak. There have been no reported deaths, but health officials say 43 people in 12 states have been sickened. Twenty-two people in Canada were also sickened.Even though romaine from the Yuma, Arizona, region is not implicated in the current outbreak, it was blamed for an E. coli outbreak this spring that sickened more than 200 people and killed five. Contaminated irrigation water near a cattle lot was later identified as the likely source.Leafy greens were also blamed for an E. coli outbreak last year. U.S. investigators never specified which salad green might be to blame for those illnesses, which happened around the same time of year as the current outbreak. But officials in Canada identified romaine as a common source of illnesses there.The produce industry is aware the problem is recurring, said Jennifer McEntire of the United Fresh Produce Association."To have something repeat in this way, there simply must be some environmental source that persisted," she said. "The question now is, can we find it?"Growers and handlers in the region tightened food safety measures after the outbreak this spring, the industry says. Steps include expanding buffer zones between cattle lots and produce fields. But McEntire said it's not known for sure how the romaine became contaminated in the Yuma outbreak. Another possibility, she said, is that winds blew dust from the cattle lot onto produce.McEntire said the industry is considering multiple theories, including whether there is something about romaine that makes it more susceptible to contamination. Compared with iceberg lettuce, she noted its leaves are more open, thus exposing more surface area.Romaine harvesting just recently began shifting from the Central Coast growing regions in central and northern California to other regions. Since romaine has a shelf life of about 21 days, health officials said last week they believed contaminated romaine could still be on the market or in people's homes.Food poisoning outbreaks from leafy greens are not unusual. But after a 2006 outbreak linked to spinach, the produce industry took steps it believed would limit large scale outbreaks, said Timothy Lytton, a Georgia State University law professor. The outbreak linked to romaine earlier this year cast doubt on how effective the measures have been, he said.But Lytton also noted the inherent risk of produce, which is grown in open fields and eaten raw.The FDA said the produce industry also agreed to consider longer-term labeling options that would help identify and trace leafy greens.___The Associated Press Health & Science Department receives support from the Howard Hughes Medical Institute's Department of Science Education.

NEW YORK — The American Museum of Natural History is removing a statue of Theodore Roosevelt on horseback with a Native American man and an African man on his sides after objections that it symbolizes colonial expansion and racial discrimination. Mayor Bill de Blasio said Sunday the city supports removal of the statue because it depicts Black and Indigenous people as subjugated and racially inferior. The statue at the museum's Central Park West entrance depicts Roosevelt on the horse with the Native American man and the African man standing on either side. The museum’s president, Ellen Futter, tells the New York Times the decision to remove the bronze statue comes amid the movement for racial justice following the killing of George Floyd. 756

NEW YORK (AP) — A new federal report shows vaping rates among U.S. teenagers fell dramatically this year.The drop comes in the wake of last year's outbreak of vaping-related illnesses and deaths.The national survey found that just under 20% of high school students and 5% of middle schools students were recent users of electronic cigarettes and other vaping products.That marks a big decline from a similar survey last year that found about 28% of high school students and about 11% of middle school students recently vaped. That's a decline of about 1.8 million teens total.The survey was done by the U.S. Food and Drug Administration and Centers for Disease Control and Prevention. They looked at survey data from middle school and high school students, grades 6-12.Despite the progress in lowering the number of teens using e-cigarettes, there are 3.6 million youth who currently use them. Of those, almost 83% use flavored e-cigarettes or vaping products.In addition to the survey, the FDA announced their premarket review requirement of tobacco products to ensure they go through a “robust scientific evaluation” before hitting store shelves. 1156

NEW YORK (AP and KGTV) — Sears is closing 80 more stores, including six locations in San Diego, as it teeters on the brink of liquidation.The iconic retailer, once the nation's largest department store chain, set a deadline of Friday for bids for its remaining stores to avert closing down completely.Sears has not received any bids as of Friday afternoon.The retailer that began out as a mail order catalog in the 1880s has been in a slow death spiral, hobbled by the Great Recession and then overwhelmed by rivals both down the street and across the internet.The 80 stores are due to close by March. That's in addition to 182 stores already slated for closure, including 142 by the end of 2108 and 40 by February. The company filed for Chapter 11 bankruptcy protection in October , saying at the time it would close more than 20 percent of all stores, keeping open only its 500 most profitable locations.Sears Holdings Corp., which also runs Kmart, joins the list of retail brands taken over by hedge funds that collapsed under the weight of debt forced upon them.Under hedge fund manager Eddie Lampert, Sears has bought time by spinning off stores and putting on the block the brands that had grown synonymous with the company, such as Craftsman. The company's chairman and biggest shareholder, Lampert loaned out his own money and put together deals to keep the company afloat and to turn whatever profit he could for ESL hedge fund. Lampert and ESL have been trying to buy the rest of Sears for up to .6 billion in cash and stock.But no official bid appeared to have emerged as of 4 p.m. E.T. Friday. Sears declined to comment. 1642
