There was an increase in both OTF-S incidents (from six in 2020 to eight in 2021) and OTF-W incidents (from 10 to 11). New TB incidentsĪ total of 19 new TB incidents were detected in Berkshire in 2021, an increase from 16 new incidents in 2020, as displayed in Figure 1. There were no Exempt Finishing Units ( EFUs) in Berkshire in 2021 - EFU are for the fattening of cattle from 6-monthly and annually tested herds that have not been pre-movement tested for TB.Ĭattle herds in the western half of Berkshire routinely undergo 6-monthly surveillance testing, however 14% of cattle herds in this area were eligible for annual testing under the earned recognition scheme in 2021. There were 2 AFUs without grazing in Berkshire in 2021. Markets close to Berkshire include Salisbury market in the neighbouring High Risk Area ( HRA) county of Wiltshire, and Thame market in Oxfordshire (Edge Area). The overall number of cattle and herds in the county continued to fall from previous years.īerkshire had no livestock markets or abattoirs in 2021. The majority of herds are small and 66% of them have fewer than 50 cattle, as shown in Appendix 1 and 2. There are approximately 200 cattle herds in Berkshire and beef herds are the predominant cattle enterprise in the county. Hence measures of incidence and prevalence in this report may be lower than those reported in the official TB statistics. TB incidents in Approved Finishing Units ( AFUs) without grazing are not included in the prevalence and incidence calculations in this report due to the limited epidemiological impact of these incidents.įurthermore, herds restricted because of an overdue test rather than a TB incident are also excluded from calculations. OTF-S incidents are triggered by reactors to the Single Intradermal Comparative Cervical Tuberculin ( SICCT) test, but without subsequent detection of TB lesions or positive culture results in any of those animals. bovis-positive culture results from tissue samples collected from carcases during the post-mortem inspection, or both. OTF-W incidents are those involving one or more test reactors with typical lesions of TB identified at post-mortem meat inspection, or one or more animals with M. This includes ‘Officially Tuberculosis-Free Status Withdrawn’ ( OTF-W) incidents and ‘Officially Tuberculosis-Free Status Suspended’ ( OTF-S) incidents. Unless otherwise specified, this report includes all new TB incidents detected during the reporting period. This includes, but is not limited to farmers, veterinarians, policy makers and the scientific community.ĭetails of the data handling methodology used in this report, a glossary of terms, and the TB control measures adopted in the Edge Area, can be found in the explanatory supplement for the annual reports 2021. This report is intended for individuals involved in the control of TB, both locally and nationally. Although other sources may refer to TB ‘breakdowns’, this report will use the term ‘incidents’ throughout. bovis), and the disease is subsequently referred to in this report as TB.
