    Salmonella Outbreak Prompts Egg Recall by Wisconsin Farm

    Officials said 65 people in nine states have been infected in the outbreak, which has been traced to an egg farm. No deaths have been reported.A salmonella outbreak that has sickened dozens of people in nine states prompted a recall of certain brands of eggs on Friday after officials said they traced the source of the infections to a farm in Wisconsin.State health officials said that 42 of the 65 people infected were in Wisconsin. Many people reported eating eggs at restaurants in the state before they got sick.Officials were able to trace the source of the eggs to Milo’s Poultry Farms of Bonduel, Wis., where they identified the outbreak strain in a packing facility and a hens egg-laying house, the U.S. Centers for Disease Control and Prevention said.All carton sizes and egg types produced at the farm, which either bear the label “Milo’s Poultry Farms” or “Tony’s Fresh Market,” were recalled by the farm, the U.S. Food and Drug Administration said.The eggs were distributed to retail stores and food service suppliers in Illinois, Michigan and Wisconsin, the F.D.A. said. The recall includes all expiration dates. The exact number of eggs recalled was not immediately available.No deaths have been reported in the outbreak, but 24 people were hospitalized. The first case was reported in late May, but most infections were reported in July and August, according to the C.D.C.The reported number of people infected is likely an undercount because it usually takes weeks to determine if an infection is part of an outbreak and because some people may recover without testing for the bacteria, the C.D.C. said.Aside from Wisconsin, infections were reported in California, Colorado, Illinois, Iowa, Michigan, Minnesota, Utah and Virginia. Illinois reported the second-highest number of infections with 11, followed by Minnesota, which reported three.The symptoms of the bacterial infection include diarrhea, fever and abdominal pain and usually begin within three days of ingesting the contaminated food, the F.D.A. said.Symptoms usually clear up within a week, but people with weakened immune systems, including young children and older adults, are more susceptible to severe, and sometimes fatal, infections, the F.D.A. said.The egg recall came after a deadly summer outbreak of listeria that prompted the recall of seven million pounds of Boar’s Head deli meat products.That outbreak has resulted in nine deaths and dozens of hospitalizations and the temporary shutdown of a Boar’s Head plant in Virginia, where inspectors had found black mold, water dripping over meat and dead flies.

    Ancient Maya Genomes Sequenced for First Time

    Thousand-year-old DNA from Chichén Itzá offers eye-opening details of the religious rituals of ancient Maya.In the spring of 1967, workers building a small airport behind Chichén Itzá, the ancient Maya city in Mexico, ran into a problem: Their excavations had uncovered human remains in the pathway of the proposed runway. The airport was set to serve V.I.P.s who wanted to visit Chichén Itzá. But with the remains so close to a major archaeological site, the work had to be halted until the bones could be examined.Any hope for a quick resolution dissolved when archaeologists who were called to the scene uncovered a chultún — an underground rainwater-storage container that, in Maya mythology, was viewed as an entrance to the subterranean land of the dead. Connected to the cistern was a cave containing more than 100 sets of human remains, almost all belonging to children. In a push to finish the airport, researchers were given just two months to excavate and exhume the cache of bones.Nearly 60 years later, ancient DNA extracted from 64 of the children is offering new insights into the religious rituals of the ancient Maya and their ties to modern descendants. In a paper published on Wednesday in the journal Nature, an international cohort of researchers revealed that the children — sacrificial victims killed between 500 and 900 A.D. — were all local Maya boys that may have been specifically selected to be killed in sibling pairs.“These are the first ancient Maya genomes to be published,” said Johannes Krause, an archaeogeneticist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. The DNA work provided a previously unseen glimpse into the identities of the sacrificed children. “One feels quite moved by such a finding,” Dr. Krause said, noting that he himself has a young son.The search into the genome of the Maya boys did not start as an exercise in ancient Maya rituals. In the mid-2000s, Rodrigo Barquera — now an immunogeneticist at the Max Planck Institute — was hoping to discover the genetic legacy of Mesoamerica’s deadliest pandemic.In 1545, an outbreak of Salmonella enterica spread like wildfire across what is now Mexico. Over the next century, the disease killed up to 90 percent of the Indigenous population. Pandemics like these often leave their mark on the immune genes of survivors. To uncover this genetic legacy, Dr. Barquera and his colleagues needed to compare the DNA from the precolonial remains with that of people who were born after the calamity.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
