Speaking at the MSD Animal Health sponsored National Mastitis Panel, David said that more widespread understanding of the issues is urgently required particularly amongst farmers and cattle vets if real progress is to be made.
David said: "There are some notable examples of veterinary practices that have worked with their clients to eliminate the use of CIAs. These are the exceptions, but they illustrate what is possible. As an industry, we need to speed up the rate of change and make a concerted effort to ensure more responsible use of antibiotics becomes the norm, sooner rather than later."
David quoted the British Cattle Veterinary Association (BCVA) position on the responsible use of medicines, which includes the recommendation of minimal use of third and fourth generation cephalosporins, fluoroquinalones and colistin, with these CIAs being limited to use where it has been demonstrated by sensitivity testing that they are the only suitable option to avoid unnecessary suffering.
"There has been agreement on this position amongst the veterinary associations, farmer organisations and milk buyers, but there needs to be more widespread awareness at producer level, particularly within the vet and farmer relationship.
"Farms with a robust herd health plan, where challenges are reduced, will be in the best position to minimise use of CIAs. This takes time and is most effective where there is good cooperation between the farm and its veterinary practice.
"Achieving a significant reduction in the use of CIAs voluntarily will not only minimise the likelihood of disruptive and potentially punitive legislation but will put our cattle industry on the front foot and strengthen its position in global markets."
FMDMost of you will be aware that IP8 was declared yesterday. This is a farm in the POZ that was slaughtered on suspicion after detection during surveillance visits. This has lead to further slight changes in the boundaries of the PZ and SZ. These were early lesions and initial laboratory results confirm this.
The epidemiology of the spread of FMD in the area north of Egham suggests that cattle on 4 premises in the vicinity of IP8 have been exposed to infection either via possible aerosol or fomite spread and are likely to develop disease. These premises will be culled as dangerous contacts.
BLUETONGUEThe various zones for controlling Bluetongue have now been defined. These are difficult to describe because they use roads etc. as boundaries but detailed maps and description of the boundaries are available at:
http://www.defra.gov.uk/animalh/diseases/notifiable/bluetongue/pdf/declaration-bt-pzcz290907.pdf
When farms straddle a road that is a boundary the whole of the farm is classed as being in the zone. It may be possible to put parts of a holding that is outside the zone as a separate unit with consultation with local Animal Health office.
The movement restrictions between the various FMD and BT zones are available at

Defra are worried that farmers are not reporting cases of BT because they feel there is nothing that can be done so why bother. It is still a notifiable disease and there is a need to monitor spread for various trade implications. There are, of course, likely to be welfare considerations with clinically affected cases. These will need to be addressed with veterinary consultation and may involve symptomatic treatment or euthanasia.
The prevalence of the disease in infected herds/flocks is still low with 1:53 and 1:190 being affected on surveillance.
