"Swallows, swifts and house martins were once a common sight over UK towns and cities, dextrously catching insects on the wing. But these spring and summer visitors are becoming increasingly rare, according to the definitive survey of the country’s birds."
"An unusual surge in flu viruses detected at wastewater treatment plants in California and other parts of the country is raising concerns among some experts that H5N1 bird flu may be spreading farther and faster than health officers initially thought."
"It emerged as a powerful tool for public health officers during the COVID-19 pandemic, when it was used to gauge the prevalence of coronavirus in communities across the nation. But wastewater surveillance — the testing of sewage for signs of pathogens such as SARS-CoV-2, poliovirus and mpox virus — has yet to be employed in the tracking of H5N1 bird flu virus."
"The bird flu virus sweeping across dairy farms in multiple states has acquired dozens of new mutations, including some that may make it more adept at spreading between species and less susceptible to antiviral drugs, according to a new study."
"The first calls that Dr. Barb Petersen received in early March were from dairy owners worried about crows, pigeons and other birds dying on their Texas farms. Then came word that barn cats — half of them on one farm — had died suddenly."
"On Friday, Colorado became the latest state to detect the bird flu virus spreading in dairy cattle. It follows revelations earlier in the week that viral fragments are turning up in retail milk."
"Federal regulators have discovered fragments of bird flu virus in roughly 20 percent of retail milk samples tested in a nationally representative study, the Food and Drug Administration said in an online update on Thursday." "There is no evidence that the milk is unsafe to drink, scientists say. But the survey result strongly hints that the outbreak may be widespread."
"Dairy cows must be tested for bird flu before moving across state lines under a federal order to be issued Wednesday, as evidence mounts the virus is more widespread than feared among cows in the United States."
"As a competing bill emerges, supporters defend RAWA as the ’gold standard.’"
"Viral fragments of bird flu have been identified in samples of milk taken from grocery store shelves in the United States, a finding that does not necessarily suggest a threat to human health but indicates the avian flu virus is more widespread among dairy herds than previously thought, according to two public health officials and a public health expert who was briefed on the issue."
