APHIS provides shipping boxes and labels for the submission of heads for scrapie testing at no cost to producers. Many veterinary diagnostic laboratories also accept heads for scrapie testing. To request a box or more information on sample submission, contact the veterinary services field office for Oregon or call: 866-873-2824.
At the end of FY 2016, the percent of cull black face sheep found positive at slaughter was 0.01 percent a 99 percent decrease compared to FY 2003. At the end of FY 2016, the percent of cull sheep found positive at slaughter and adjusted for face color* was 0.001 percent. As of November 30, 2016, no animals have tested positive for classical scrapie.
Two infected and three source flocks were designated in FY 2016. No classical scrapie infected or source flocks have been designated in FY 2017. One flock was designated as a Nor98-like source flock in October 2016 based on a sample submitted at the end of FY 2016. Epidemiological studies indicate that Nor98-like scrapie is either not transmissible or poorly transmissible under natural conditions. Further, the World Organization for Animal Health has determined that Nor98-like scrapie is distinct from classical scrapie and is not a listed disease of trade concern. Animals in Nor98-like scrapie infected flocks are not removed and are free to move once they have been officially identified.
Only one positive goat (FY 2015) has been found through RSSS since the start of RSSS in 2003. Based on all goats sampled at slaughter, the prevalence of scrapie in U.S. cull goats is 0.002 percent with an upper 95 percent confidence limit of 0.004 percent.
Updated May 2016 Scrapie Free Flock Certification Program standards are in effect. They are available on the APHIS SFCP website at: http://www.aphis.usda.org/animal-health/scrapie
The basic structure of the program has not changed. There are still two categories in the SFCP: the Export Category (with Export Monitored flocks and Export Certified flocks) and the Select Category (Select Monitored flocks). The updates address/clarify:
• Sampling requirements, advancement, and genotyping lambs/kids in genetically resistant flocks;
• Veterinary inspection of cull animals;
• Imported embryos/oocytes;
• Animals originating from Inconsistent States;
• Special circumstances involving “Lost to Inventory” and “Found Dead” animals; and
• Reporting requirements for the use of milk/colostrum from a lower status flock.

Federal requirements for Animal Disease Traceability (ADT) became effective March of 2013. In general, there was no significant change in the requirements for interstate movement of sheep and goats as the ADT rule references existing identification regulations. The federal scrapie program regulations pertaining to sheep have required official identification of animals in interstate commerce since 2001.
The ADT rule did create an opportunity for us to revisit the importance of identification for us here in Oregon. Just remember, as a general rule, animals leaving the farm must have identification. Oregon Administrative Rules state that all sexually intact sheep and goats of any age leaving the flock of origin, which are not in slaughter channels, and all sheep over 18 months of age in slaughter channels must have official identification for within-state and interstate movement for any purpose. Regulatory compliance checks are focused on animal concentration points such as markets, dealers and slaughter facilities.
Maintaining a high percentage of identification compliance is important in maintaining the state’s “Consistent” status. This means that we fulfill all of the USDA standards including official identification requirements. Historically, Oregon has managed to fulfill all of the federal requirements to maintain its Consistent status. In the past few years we have fallen behind in primarily the identification requirement. Loss of Consistent status results in increased requirements for interstate movement by the USDA and possible restrictions being imposed by receiving states. USDA conducted a review of Oregon’s scrapie program in 2014. We passed the review, but the importance of complying with identification requirements was the central theme of the review.
Some regions within the state of Oregon are still taking sheep and goats to livestock markets without official identification. Why would this be important you might ask? The bottom line is that livestock markets, along with the producers that consign animals, are required to officially identify them at this point of commerce. At this point the livestock market is expected to identify all animals not showing official identification. This is not really a problem on sale days with a few animals, but on busy days with hundreds of animals arriving not identified, the market is under pressure to stay in compliance. And if there happens to be an inspector at the market that day then deficiencies will be noted which reflects negatively on our Consistent state status.
Official identification in sheep and goats include flock id tags, which can be a bangle, button, or metal tag. Note that the official US shield should be present along with flock number and individual number to qualify. Other methods are the Scrapie program tags, serial ID tags, Animal Identification Number (AIN) tags, and registry tattoos.
As an Oregon producer, how can you help? If your operation involves selling sheep and goats through the livestock markets, for exhibition, or selling to out of state buyers, then please help by applying official identification before they leave your farm. Be aware of these requirements and pass on the word. This will aid Oregon in maintaining a Consistent state status. Consistent status benefits all Oregon producers. ·
