Hundreds have been sickened with salmonella in recent weeks due to the presence of backyard poultry, the Centers for Disease Control and Prevention said on Thursday. According to CDC statistics, 227 have been sickened since May 16 by chickens and ducks being raised in backyard flocks. Overall, 279 people have reported salmonella illnesses this year from backyard poultry. The CDC says that many of those who reported an illness got their chicks or ducklings from agricultural stores, websites, and hatcheries. Nearly one-third of those sickened are younger than age 5. Of the 279 reported cases of salmonella, 40 have caused hospitalization. The CDC added that there has not been any reported fatalities. The CDC offers the following advice to the public: Always wash your hands thoroughly with soap and water right after touching poultry or anything in their environment. Use hand sanitizer if soap and water are not immediately available.Do not let backyard poultry inside the house, including in bathrooms. Be especially careful to keep them out of areas where food or drink is prepared, served, or stored, such as kitchens and outdoor patios.Set aside a pair of shoes to wear while taking care of your birds and keep those outside of your home.Children younger than 5, adults over 65, and people who have health problems or take medicines that lower the body’s ability to fight germs and sickness shouldn’t handle or touch chicks, ducklings, or other poultry.Don’t eat or drink where poultry live or roam.Don’t kiss backyard poultry, or snuggle them and then touch your face or mouth.Stay outdoors when cleaning any equipment or materials used to raise or care for poultry, such as cages, or feed or water containers.The CDC says that salmonella symptoms include diarrhea, fever, and stomach cramps. The illness typically goes away after one week without any treatment. 1888

Former Vice President Joe Biden responded to criticism Thursday after he called Vice President Mike Pence a "decent guy" during a speech in Omaha, a comment that frustrated some on the left because of Pence's position on LGBTQ rights.Biden's comments about Pence came as he discussed foreign policy and how the international community had reacted to Pence during the vice president's speech at the Munich Security Conference earlier in February."The fact of the matter is it was followed on by a guy who's a decent guy, our vice president, who stood before this group of allies and leaders and said, 'I'm here on behalf of President Trump,' and there was dead silence. Dead silence," Biden recounted Thursday at the Chuck Hagel Forum in Global Leadership at the University of Nebraska at Omaha.The "decent guy" comment prompted a round of criticism on Twitter. 873

For the second time in less than six months, a brand-new Boeing aircraft has crashed just minutes into a flight.All 157 people on board the Ethiopian Airlines flight from Addis Ababa that crashed on Sunday morning have died, the airline has confirmed.The tragedy follows the Lion Air flight that went down over the Java Sea in late October, killing all 189 people on board.There is no suggestion yet as to what caused the latest disaster, and no evidence that the two incidents are linked in causality.What is known, however, is that both flights took place on the Boeing 737 MAX 8 -- a new model recently unveiled to great fanfare by the US aviation giant, that saw its first flight less than two years ago."It's highly suspicious," said Mary Schiavo, a CNN aviation analyst and the former Inspector General of the U.S. Transportation Department. "Here we have a brand-new aircraft that's gone down twice in a year. That rings alarm bells in the aviation industry, because that just doesn't happen."Adding to concerns are some similarities between the two flights. Both were operated by well-known airlines with strong safety records -- but the Lion Air flight went down 13 minutes after take off, while Sunday's Ethiopian Airlines flight crashed just six minutes into its journey.And while the Ethiopian Airlines did not see the wild fluctuations in altitude that the Lion Air flight saw, it did dip and then regain altitude before it crashed."The similarities with Lion Air are too great not to be concerned," Schiavo said.Data from flight recorders awaitedAt the root of October's Lion Air crash was a new safety system installed in the MAX 8 plane, known as the Maneuvering Characteristics Augmentation System (MCAS), that automatically pulls the plane's nose down if data suggests it is at risk.In that flight, the system was responding to faulty data that suggested the nose was tilted at a higher angle than it was, indicating the plane was at risk of stalling.The pilots subsequently engaged in a futile tug-of-war with the plane's automatic systems, trying to reverse a nosedive that should not be triggered so soon after takeoff. Boeing has argued that pilots should have identified the system was in operation, and turned it off."All pilots should have been trained on that function after Lion Air," Schiavo added. "Boeing did something very unusual for any manufacturer -- it sent out an emergency bulletin and told all airlines to make sure they trained the pilots in the shut-off procedure.""This is one of the things that should never be happening after takeoff," Schiavo said.It is too early for conclusions to be drawn as to whether the same issue occurred on the Ethiopian Airlines flight -- but a clue could come sooner rather than later."We will not get a final determination for two or three years, but we will get information from the flight recorders -- which I'm guessing will be fairly easy to retrieve -- in a matter of weeks," said CNN anchor Richard Quest, who specializes in aviation."At the moment, it seems a coincidence" that both disasters occurred on the same aircraft, Quest said. "But I'm guaranteeing to you that the authorities will be examining just how close a coincidence, and whether there are common circumstances between the two," he said."Two brand new planes have crashed from two respected airlines," Quest added. "Ethiopian is a very, very well-run airline. There is no safety issue on Ethiopian Airlines."Possible repercussions for Boeing If investigators do uncover a similar cause of the two accidents, the repercussions for Boeing could be dramatic."The Lion Air flight was a big deal for Boeing, but they managed to overcome it," Schiavo says. "They put out the emergency warning about training, and the industry went on. With the second one, I don't think everybody's going to forget."The MAX 8 could be grounded if a link is found -- either by the company itself, or by governments, though the former is more likely to come first, Schiavo says. "The voluntary basis is always the better way to go -- but it will be expensive for Boeing."Airlines with MAX 8 aircraft in their fleet -- and those with outstanding MAX 8 orders -- are likely to be watching developments closely in the coming days and weeks.According to 4284
