Small Ruminant Expert Group (SREG) veterinary lead

SREG veterinary lead - Amanda CarsonThe SREG veterinary lead is Amanda Carson (07909532229).

Amanda has been the SREG veterinary lead since April 2014. She leads the Defra-funded small ruminant disease scanning surveillance project in APHA, and is a committee member of the Goat Veterinary Society and the Association of Government Veterinarians.

SREG members

To support the SREG veterinary lead, the group has representation from Veterinary Investigation Officers from APHA and SRUC Veterinary Services representatives.

In addition, there are APHA members on SREG providing expertise for specific disciplines (e.g. epidemiology, virology, bacteriology, pathology, field veterinarians and welfare) and specific diseases (e.g. parasitic diseases). There is also representation from those involved in International Disease Monitoring in APHA.

SREG non-APHA members include representatives from:

SREG surveillance reports

SREG contributes interesting and unusual small ruminant cases, highlights small ruminant disease alerts or findings and provides focus articles relating to small ruminants for the APHA Veterinary Record monthly disease surveillance report. These are compiled together with contributions from other Species Expert Groups.

Quarterly GB Small Ruminant Disease Surveillance and Emerging Threats reports are compiled by SREG. They summarise investigations into threats and other surveillance issues to inform governments, the veterinary profession and livestock farming industries of new or re-emerging threats to cattle health or changing trends among existing ones.
