一 | DES MOINES, Iowa -- Two commercial turkey farms in Iowa have been hit by the reemerging highly pathogenic bird flu, causing about 100,000 birds to be killed to prevent the disease from spreading.The Iowa Department of Agriculture reported the infected commercial poultry flocks within weeks of a turkey farm in South Dakota and one in Utah reporting the first outbreaks in the U.S. since April, raising concerns that more would follow. The U.S. Department of Agriculture shows 12 commercial flocks in South Dakota, Utah and Minnesota have been affected in October, totaling more than 500,000 birds.Bird flu last year cost U.S. poultry producers nearly 59 million birds across 47 states, including egg-laying chickens and turkeys and chickens raised for meat, making it the country’s deadliest outbreak ever, according to USDA figures. The outbreak caused spikes in egg and turkey prices for consumers and cost the government over $660 million.Iowa was the hardest-hit state last year, with nearly 16 million birds lost, but there hadn’t been a case reported in the state since March.Iowa's department reported Friday that one commercial turkey facility of about 50,000 birds in Buena Vista County was affected. Another facility of about 47,500 turkeys in neighboring Pocahontas County was confirmed Monday.In Guthrie County, about 50 backyard birds were also infected, the department said.Before last week, the only reports of bird flu in recent months in the U.S. in recent months were sporadic appearances in backyard flocks or among wild birds such as ducks, geese and eagles. While wild birds often show no symptoms of avian influenza, infections in them are a concern to the poultry industry as migration season gets underway. Migrating birds can spread the disease to vulnerable commercial flocks.Bird flu infections are relatively rare in humans and aren’t considered a food safety risk. But as it hits other species, including some mammals, scientists fear the virus could evolve to spread more easily among people. Cambodia this week reported its third human death from bird flu this year.。 Convinced social media platforms are fueling a mental health crisis among the nation’s youth, public officials in New York announced new legislation Wednesday that would restrict algorithms that target young users."Young New Yorkers are struggling with record levels of anxiety and depression, and social media companies that use addictive features to keep minors on their platforms longer are largely to blame," New York Attorney General Letitia James said.The legislation would, among other things, give her office new enforcement power over social media companies.Algorithmic feeds are designed to harness personal data to serve users content that keeps them engaged for as long as possible. Sponsors of the legislation said that has increased the addictive nature of social media platforms and heightened the risk to young users’ well-being.Facebook, Instagram, TikTok and YouTube would all be subject to the legislation that allows users under 18 to opt out of receiving algorithmic feeds, allow parents to allow algorithmic feeds to limit access between 12 a.m. and 6 a.m. and prohibit social media platforms from sending notifications to minors during those same hours without verifiable parental consent.The attorney general’s office would be authorized to bring an action to enjoin or seek damages or civil penalties of up to $5,000 per violation.Back in May, U.S. Surgeon General Vivek Murthy warned that excessive social media use can be a "profound risk" to the mental health of youth in the United States."I’m very concerned that social media has become an important contributor to the pain and the struggles that many of our young people are facing," Murthy said in an interview on ABC News Live.A surgeon general’s advisory is "reserved for significant public health challenges that require the nation’s immediate awareness and action," according to the report released by the surgeon general’s office.The surgeon general said that while we’re in the "middle of a youth mental health crisis" it’s important to identify possible causes. The advisory recognizes that social media has both positive and negative effects on young people, but that ultimately there’s not enough "research and clear data" to determine if it’s "safe" for adolescents to use.。
