USDA Confirms Highly Pathogenic H5N2 Avian Influenza in Commercial Turkey Flocks in Missouri CDC considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry, to be low WASHINGTON, March 10, 2015 -- The United States Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic H5N2 avian influenza (HPAI) in two separate commercial turkey flocks in Missouri. The flocks are located in Jasper County and Moniteau County, within the Mississippi flyway where this strain of avian influenza has previously been identified. CDC considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry, to be low. Samples from the turkey flocks, which experienced increased mortality, were tested at the Missouri Department of Agriculture Veterinary Diagnostic Laboratory and the APHIS National Veterinary Services Laboratories in Ames, Iowa confirmed the findings. APHIS is working closely with the Missouri Department of Agriculture on a joint incident response. State officials quarantined the affected premises and the remaining birds on the properties will be depopulated to prevent the spread of the disease. Birds from the involved flocks will not enter the food system. No human infections with these viruses have been detected at this time. The Missouri Department of Agriculture is working directly with poultry workers at the affected facility to ensure that they are taking the proper precautions. As a reminder, the proper handling and cooking of poultry and eggs to an internal temperature of 165 F kills bacteria and viruses. As part of existing avian influenza response plans, Federal and State partners are working jointly on additional surveillance and testing in the nearby area. The United States has the strongest AI surveillance program in the world, and USDA is working with its partners to actively look for the disease in commercial poultry operations, live bird markets and in migratory wild bird populations. USDA will be informing the World Organization for Animal Health (OIE) as well as international trading partners of this finding. USDA also continues to communicate with trading partners to encourage adherence to OIE standards and minimize trade impacts. OIE trade guidelines call on countries to base trade restrictions on sound science and, whenever possible, limit restrictions to those animals and animal products within a defined region that pose a risk of spreading disease of concern. These virus strains can travel in wild birds without them appearing sick. People should avoid contact with sick/dead poultry or wildlife. If contact occurs, wash your hands with soap and water and change clothing before having any contact with healthy domestic poultry and birds. All bird owners, whether commercial producers or backyard enthusiasts, should continue to practice good biosecurity, prevent contact between their birds and wild birds, and report sick birds or unusual bird deaths to State/Federal officials, either through their state veterinarian or through USDA's toll-free number at 1-866-536-7593. Additional information on biosecurity for backyard flocks can be found at <http://healthybirds.aphis.usda.gov/>http://healthybirds.aphis.usda.gov. Additional background Avian influenza (AI) is caused by an influenza type A virus which can infect poultry (such as chickens, turkeys, pheasants, quail, domestic ducks, geese and guinea fowl) and is carried by free flying waterfowl such as ducks, geese and shorebirds. AI viruses are classified by a combination of two groups of proteins: hemagglutinin or "H" proteins, of which there are 16 (H1H16), and neuraminidase or "NN" proteins, of which there are 9 (N1N9). Many diffferent combinations of "H" and "N" proteins are possible. Each combination is considered a different subtype, and can be further broken down into different strains. AI viruses are further classified by their pathogenicity (low or high) the ability of a particular virus strrain to produce disease in domestic chickens. The HPAI H5N8 virus originated in Asia and spread rapidly along wild bird migratory pathways during 2014, including the Pacific flyway. In the Pacific flyway, the HPAI H5N8 virus has mixed with North American avian influenza viruses, creating new mixed-origin viruses. These mixed-origin viruses contain the Asian-origin H5 part of the virus, which is highly pathogenic to poultry. The N parts of these viruses came from North American low pathogenic avian influenza viruses. USDA has identified two mixed-origin viruses in the Pacific Flyway: the HPAI H5N2 virus and new HPAI H5N1 virus. The new HPAI H5N1 virus is not the same virus as the HPAI H5N1 virus found in Asia, Europe and Africa that has caused some human illness. Only the HPAI H5N2 virus has been detected in both the Pacific and Mississippi Flyways. Detailed analysis of the virus is underway in cooperation with the U.S. Centers for Disease Control and Prevention. None of these viruses have been identified in humans, nor are expected to pose a public health risk.

USDA Provides Guidance to Breeders and Dealers Who Use Cage Cards 03/10/2015 USDA Animal Care has created a tech note for commercial breeders and dealers who use cage cards to satisfy recordkeeping requirements and/or identify their puppies and kittens. Animal Welfare Act regulations require USDA-licensed breeders and dealers to keep records on all dogs and cats in their possession. For puppies and kittens under 16 weeks of age, we allow breeders and dealers to maintain these records on APHIS Form 7005 (Record of Acquisition of Dogs and Cats on Hand) or on cage cards placed on the animals' primary enclosure. For those breeders and dealers who prefer using cage cards, this new tech note will explain what information is needed on the cards, how long the cards should be kept and where they should be located. We've posted the tech note <http://www.aphis.usda.gov/animal_welfare/downloads/tech-note-cage-cards.pdf>here on our website. -- Cayugabirds-L List Info: http://www.NortheastBirding.com/CayugabirdsWELCOME http://www.NortheastBirding.com/CayugabirdsRULES http://www.NortheastBirding.com/CayugabirdsSubscribeConfigurationLeave.htm ARCHIVES: 1) http://www.mail-archive.com/cayugabirds-l@cornell.edu/maillist.html 2) http://www.surfbirds.com/birdingmail/Group/Cayugabirds 3) http://birdingonthe.net/mailinglists/CAYU.html Please submit your observations to eBird: http://ebird.org/content/ebird/ --
