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.

North Korea is getting increasingly angry at the US, as talks are deadlocked and tensions between the two countries are on the rise, a source familiar with the discussions told CNN.US and foreign sources close to the talks paint a picture that's starkly different from the image President Donald Trump sought to convey Wednesday, when he told reporters the administration is "very happy with how it's going with North Korea. We think it's going fine."Trump had been asked about the administration's announcement, in the middle of the night as Tuesday's midterm elections results were coming in, that Secretary of State Mike Pompeo's Thursday meeting with a key aide to North Korean leader Kim Jong Un had been postponed."We're very happy with how it's going with North Korea. We think it's going fine. We're in no rush. We're in no hurry," Trump told reporters at a White House press conference. "The sanctions are on. The missiles have stopped. The rockets have stopped. The hostages are home. The great heroes are home." 1030

New York, New Jersey and Connecticut are imposing a 14-day quarantine on incoming travelers from states with a high transmission rate of the coronavirus."We worked really hard to get the viral transmission rate down, and we don't want to see it go up," New York Gov. Andrew Cuomo said. "So we are jointly instituting that travel advisory today."The travel advisory will apply to states with two criteria: States that have an infection rate above 10 cases per 100,000 people and states where 10% of the total population test positive. Both criteria are measured on a seven-day rolling average.As of Wednesday, the states that the travel advisory applies to include Alabama, Arizona, Arkansas, Florida, North Carolina, South Carolina, Washington, Utah and Texas.This story was originally published by Lauren Cook and Mark Sundstrom on WPIX. 846

NEWFOUNDLAND, Pa. -- Crown-wearing worshippers held onto their AR-15 rifles, drank holy wine and exchanged or renewed wedding vows during a commitment ceremony at a Pennsylvania church Wednesday.State police and protesters stood outside the church as brides dressed in white and grooms dressed in dark suits clung to their AR-15s inside the World Peace and Unification Sanctuary.The church believes the AR-15 represents the “rod of iron” in the book of Revelation and encouraged couples to bring guns to the ceremony.An attendant was charged with the task of checking each weapon at the door to ensure it was unloaded and secured with a zip tie.The ceremony prompted an area school district to move elementary school students down the street to a different school. 772
