INTRODUCTION - Program Summary At the end of FY 2014, the percent of cull black face sheep found positive at slaughter was 0.02 percent (Chart 1). This measure decreased by 51 percent compared to FY 2013 and 98 percent compared to FY Eight source flocks (including 2 goat herds) and 3 infected flocks were designated in FY Three source flocks and 3 infected flocks were designated in FY 2014 (Chart 2), a decrease of 45 percent. One infected and two source flocks have been designated in FY At the end of FY 2014, the percent of cull sheep found positive at slaughter and adjusted for face color* was percent and is currently at percent for FY 2015 (Chart 3). This measure increased by 31 percent compared to FY 2013 and decreased 87 percent compared to FY In November 2014, the first positive goat found through RSSS was identified. Based on the goats sampled at slaughter to date, the prevalence of scrapie in U.S. cull goats is percent with an upper 95 percent confidence limit of percent. Chart 3a was added to the December 2014 report to show the percent positive goats at slaughter each FY since FY * See slide 4 for an explanation of adjusted weights. Introduction - Program Summary

INTRODUCTION - Surveillance (Part 1) Regulatory Scrapie Slaughter Surveillance (RSSS) RSSS started April 1, It is a targeted slaughter surveillance program which is designed to identify infected flocks. Samples have been collected from 459,201 animals since April 1, There have been 477 NVSL confirmed positive animals* (469 classical cases and 8 Nor98-like cases) since the beginning of RSSS. As of February 28, 2015, 15,463 samples have been collected in FY 2015, 12,352 from sheep and 3,111 from goats. As of February 28, 2015, 2 black-faced sheep and 1 goat have tested positive for scrapie in FY 2015; this is the first positive goat case found through RSSS. The weighted percentage of samples from sheep that have tested positive for each face color from FY 2003 through FY 2015 is depicted in Chart 3**; percent positive goats are shown in Chart 3a. In November 2013, administrative units within APHIS Veterinary Services reorganized from 2 Regions to 6 Districts (Figure 1). The distribution of sheep and goat populations by District is depicted in Chart 4a. The number of animals collected for FY 2015 by District where collected is shown in Chart 4b. A monthly comparison of RSSS collections by fiscal year is displayed in Chart 5. Chart 6 is a retrospective 6- month rolling average of the percent positive, black-faced sheep sampled at RSSS collection sites. * RSSS positives are reported based on collection date and may have been confirmed after February 28, ** White, black and mottled face color sheep are weighted based on population. White faced sheep have the highest weight, so when the rare white face positive sheep is found it causes this statistic to markedly increase. Goats and other face colored sheep are not included in this calculation. Introduction – Surveillance (Part 1)

INTRODUCTION - Surveillance (Part 2) On-Farm Surveillance Testing sheep and goats on-farm is an essential part of scrapie surveillance. It includes both regulatory testing of scrapie exposed and potentially exposed sheep and goats and testing sheep and goats on farm for routine surveillance. As the National Scrapie Eradication Program moves closer towards meeting the goal of identifying the last remaining cases of classical scrapie, finding and testing all sheep and goats meeting targeted sampling criteria is even more important. As of February 28, 2015, 511 sheep and 214 goats have been tested on-farm for FY Twenty-eight animals (27 sheep and 1 goat) have tested positive; 26 of the positive sheep were from the same flock. The number of animals tested on-farm by month and by species for FY 2015 is shown in Chart 7. Total Animals Sampled for Scrapie Testing As of February 28, 2015, 16,188 animals have been sampled for scrapie testing in FY 2015: 15,463 RSSS samples and 725 on-farm samples (Chart 8); Of which 12,863 were sheep and 3,325 were goats. Distribution of sampling by type (RSSS or on-farm) and by species is shown in Chart 9. Introduction – Surveillance (Part 2)

INTRODUCTION - Surveillance (Part 3) State Sampling Minimums The National Scrapie Eradication Program establishes annual sheep and goat sampling minimums for each State, and tracks the States’ level of compliance with meeting these minimums. These State minimums help ensure adequate geographical representation, so that APHIS can find the last remaining cases and document freedom from scrapie. State sampling minimums are established based on the population demographics of mature sheep in each State. The calculations used to derive the sampling minimums are described in the National Scrapie Surveillance Plan. The State sampling minimums for sheep and goats, and the total number of animals sampled by State of Animal ID, are provided in the slides listed below. The percent prorated sampling minimum for sheep and goats achieved by each State in FY 2015 are depicted in Figure 2 and Figure 3.

INTRODUCTION - Positive Cases and Infected/Source Flocks Positive Scrapie Cases* Since the beginning of FY 2015, 29 sheep have tested positive for scrapie; 26 of these positives were from the same source flock. (Table 7 and Figure 4). The first RSSS positive goat was reported in November This case and a positive clinical suspect from the same herd increases the number of confirmed positive cases in goats since FY 2002 to 41 (Table 7 and Figure 5). Total positive cases reported in FY 2015 is 31. Infected and Source Flocks As of February 28, 2015, there were 5 flocks with an open source status (Figure 6). One infected and two source flocks have been designated in FY 2015 (Figure 7); two flocks completed a flock clean-up plan and were released (Figure 8). New infected and source statuses from FY 1997 to FY 2015 are depicted in Chart 2. * Samples collected between October 1, 2014 and February 28, 2015 and confirmed by March 15, Cases and New Infected/Source Flocks

INTRODUCTION - Scrapie Flock Certification Program (SFCP) As of February 28, 2015, there were 451 flocks participating in the Scrapie Flock Certification Program (SFCP). Statuses of these flocks were 172 export monitored, 17 export certified, and 262 select monitored flocks (Figure 9). SFCP open statuses by fiscal year from FY 2007 to FY 2015 are depicted in Chart 10. The current status of participating flocks is available to the public on the SFCP Web Page. 1 The current version of the SFCP standards was published June 20, A copy of the standards can be downloaded from APHIS’ SFCP Web Page. 1 Note: Flocks that have “Certified” status on the SFCP Web Page are not listed in this report because it is a transitional status concurrent with their Export Monitored status. This report is based on information and test results available at the time of report generation. Numbers are subject to change due to later reporting of test results and updates in the database.
