Comments Off on U.S. rabbit populations contend with lethal virus, RHDV2

Wildlife  officials recently announced outbreaks of Rabbit Hemorrhagic Disease Virus Type 2 (RHDV2) ravaging Texas, New Mexico, Colorado, Arizona and California. The  U.S. Department of Agriculture (USDA)  deems RHDV2 as seriously contagious and nearly always fatal amongst domestic and wild rabbit species and their close relatives, hares and pikas. RHDV2 is not zoonotic, so it won’t infect livestock, pets or humans, asserts the  California Department of Fish & Wildlife (CDFW) . Still,  Texas Parks & Wildlife (TPW)  advise against pets consuming rabbit carcasses. Rabbit Hemorrhagic Disease Virus (RHDV) is the viral agent causing rabbit hemorrhagic disease (RHD).  Science Direct  says RHDV belongs in the calicivirus family, which infects many  animals  including pigs, cattle, cats and even humans. Norovirus, for example, is a human calicivirus. But humans seem unaffected by RHDV.  Related:  What’s causing the decline in monarch butterfly populations? There are two worrisome strains of RHDV — RHDV1 and RHDV2.  House Rabbit Society ,  Veterinary Practice , as well as both the Vaccine and Veterinary Research  journals document RHDV1 as first emerging in China back in 1984, when, in just one year, 140 million rabbits were decimated. China claims that the outbreak started in Angora rabbits imported from Europe. Eventually, RHDV1 spread to over 40 countries and hit the U.S. in 2000. Given its estimated 95% mortality rate, Australia and New Zealand notoriously introduced RHDV1 into their wild rabbit populations as pest biocontrol. RHDV1 mutated, begetting RHDV2, which was first identified in 2010 when domesticated rabbits in France showed clinical signs of RHD despite being already vaccinated against RHDV1. By September 2018, RHDV2 reached the U.S., manifesting among domestic rabbits in a rural Ohio farm, documents the  Veterinary Information Network (VIN) News Service . The USDA considers both RHDV1 and RHDV2 invasive pathogens, as they are not native to North America. A  joint paper  put forth by the Center for Food Security & Public Health , Institute for International Cooperation in Animal Biologics, Iowa State University, the World Organization for Animal Health (OIE) and the USDA revealed RHD can be difficult to eradicate. Not only can the virus strains survive over seven months on rabbit carcasses, but they also withstand temperatures below freezing and above 120 degrees Fahrenheit.  House Rabbit Society  cites several differences between RHDV1 and RHDV2. Incubation is two to 10 days for RHDV1, but three to nine days for RHDV2. Rabbits with RHDV2 can be asymptomatic yet spread the virus for up to two months. There is no known cure for either strain. While a vaccine exists for RHDV1, there are currently no USDA -licensed vaccines for RHDV2. That RHDV2 can “potentially surviv[e] more than 3 months without a host” has prompted some U.S. veterinarians to import RHDV2 vaccines despite a convoluted process. The  USDA  and  VIN News Service  warn RHD is highly contagious, spreading easily by direct contact with rabbit excretions and secretions — saliva, sweat and biowaste. Sharing food, water, bedding, fomites and vehicles spreads RHD. Other vectors are infected rabbit meat, pelts, even insects. Besides farmers and pet owners, biologists and  conservationists  are worried about this virus. As declining rabbit populations have repercussions in  habitat  food chains, RHDV2 could cause severe consequences down the line. + Veterinary Information Network (VIN) News Service Via USDA Animal and Plant Health Inspection Service and House Rabbit Society Images via Pexels

Hunters issued permits to import lion trophies to United States

Comments Off on Hunters issued permits to import lion trophies to United States

A Freedom of Information Act (FOIA) request has revealed that the U.S. government has issued over three dozen permits allowing trophy parts hunted from lions to be brought back into the United States from Africa. Despite the permits’ issue, lions remain on the Endangered Species Act (ESA) due to their threatened survival status in the wild. Friends of Animals obtained the documents and released them through The Huffington Post , which reported the animal rights violation on Thursday. The memorandum , released by the United States Department of the Interior, Fish and Wildlife Service on March 1, 2018, removes trophy import bans dating as far back as 1995. “If African wildlife is to survive the next few decades in their homelands, these elephants, lions and other animals—coveted by hunters for their strength and beauty—must be worth more alive than dead. That means safeguarding habitat along with photographic safaris and ecotourism must outpace blood-drenched trophy hunting expeditions,” declared Priscilla Feral, President of Friends of Animals, in a press release. Related: The Trump Administration decides to allow the import of elephant trophies after all New rules by the Fish and Wildlife Service require the filing of a FOIA request to see the details of government-issued permits that are determined on an individual basis – information that used to be publicly available . In this case, the majority of the permit recipients are Republican donors or are part of Safari Club International, a hunting advocacy group. While big game hunters argue that their activities help conservation efforts and local economies, animal rights supporters say that killing big game animals only further endangers their already at-risk populations. + Friends of Animals Via EcoWatch and The New York Times
