Hysolv Animal Health UK has announced that it is offering a free diagnostic test which allows vets to identify the E. coli sub-types that produce the Shiga toxin associated with oedema disease in pigs.

The test, known as STEC-Check and worth £150-£200, is being sponsored by IDT Biologika GmbH. In the UK and Republic of Ireland, faeces and/or intestinal samples will be sent to the Animal Health and Plant Agency (APHA), Weybridge and SAC Consulting Veterinary Services at Penicuik to confirm results within a few days.

Hysolv says the test will provide a quick and accurate diagnosis, enabling appropriate action, including vaccination, to be taken on the farm.

Richard Brealey from Hysolv said: "Oedema disease is not always obvious and may be masked or controlled by the use of antibiotics, the use of zinc oxide or low-protein feeds which can also negatively affect productivity. This test will help confirm the presence of Shiga-toxin producing E. coli on the farm, a cause of serious losses in individual herds. We are therefore advising farmers to contact their vets to discuss using STEC-check on their farms."

According to the company, a nationwide study in Germany showed that 59% of farms where oedema was suspected were affected by Shiga toxin. 

Richard added: "The Ecoporc Shiga vaccine has been recently licensed for use in the UK. There is pressure on vets and farmers to reduce the use of antimicrobials and vaccination, together with other measures, and this will help them to do this."

In the UK farmers will be able to carry out a DIY calculation of their return on investment online, using their smartphones or by visiting the Shiga toxin website www.shigatoxin.com
