Performance Audit Report on the Control of F MD Table 3: Samples collected from FMD vaccination zones in cattle (zone 7  only) and small stock (all FMD vaccination zones) in 2013  Source:  FMD Surveillance Report 2013.  Table 3 shows that the FMD Surveillance Report 2013, prescribed samples sizes  of 470 and 950 (shown under “ expected ” column) for small stock and cattle  respectively. These sample sizes were statistically derived as the plan prescribed.  However, the Table depicts that contrary to the plan requirement, surveillance  was not carried out at all in the months of September, November and December  2013. The Table also shows that in April and May 2013, samples tested were not  consistent with sample sizes prescribed by the plan. Instead of 470 samples only  80 were tested in April and 1152 instead of 950 in May 2013. This was a clear  compromise in terms of reliability and credibility of the surveillance results as  they were not a true statistically derived representative of the animal population  in the surveyed zones. The report only provided an explanation of non-submission of samples for the  month of December 2013 which it attributed to postponement of the vaccination  30 |  P a g e Month Species Samples  Expected Tested April Small stock  470  80  May (zone 7)  Cattle 950  1152  September Cattle 950  0  November Small stock  470  0  December  Cattle 950  0  TOTAL SAMPLES COLLECTED  3790  1232
