According to the European Scientific Counsel for Companion Animal Parasites (ESCCAP), serious zoonotic diseases, currently rife across Europe, could be a far more serious threat to pet and human health in the UK than official figures suggest.

Vets and parasitologists at an ESCCAP meeting held in Bristol on 19th September, heard evidence that UK cases of diseases such as leishmaniosis and babesiosis are grossly under-reported. ESCCAP is urging vets and parasitologists to help raise awareness of the threat and lobby the Government to prevent further relaxation of pet movement restrictions.

According to DACTARI, the voluntary web-based Dog And Cat Travel And Risk Information scheme, just 19 cases of leishmaniosis, 10 babesiosis, 10 ehrlichiosis and one case of dirofilariosis had been recorded between 1 January 2003 and 30 September 2006, which are the latest figures reported on the Defra website.

But latest figures presented by Susan Shaw, senior lecturer in dermatological and applied immunology, revealed a screening programme underway at Bristol University casts serious doubts on the reliability of the Defra-backed service to monitor cases.

"From 2005 to 2007 we recorded 257 cases of leishmaniosis. The babesiosis cases you can multiply by about five, the ehrlichiosis cases by about 10 and dirofilariosis by three," Ms Shaw told delegates at the sixth ESCCAP meeting. "That is absolutely outrageous - we are dealing with a massive number of cases. I would be very concerned if we are making decisions for the UK based on the DACTARI figures."

Maggie Fisher, an independent consultant in veterinary parasitology and founding member of ESCCAP pointed out that the PETS (Pet Travel Scheme), has issued dogs and cats with passports for travel across Europe since 2000 and has proven immensely popular, with 76,000 dogs entering the UK in January to October 2007 alone.

"What is coming into the country with those animals is not well documented," said Mrs Fisher. Case studies point to harrowing experiences for individual families travelling with their dogs to mainland Europe unaware of the dangers. "One family thought they'd done everything they should because they followed the instructions under PETS. What they didn't realise is that they weren't protected against ticks, tick-borne diseases and worms whilst they were away and their dog picked up babesiosis."

Human health and veterinary professionals at the meeting explored the real threat and implications of parasites across Europe. Peter Deplazes of ESCCAP, Switzerland, reported that the human form of Echinococcus multilocularis claims three or four lives per year in Switzerland and is a very common endoparasitic diagnosis in dogs. Forty per cent of foxes are infected with E multilocularis.

Leishmaniosis causes renal failure in dogs, reported ESCCAP Spain's Lupe Miro Corrales, often leading to death or euthanasia. Worldwide more than 12 million people are already infected, and one in ten at risk of being infected. Stray dogs and cats are important carriers and almost 80 per cent of sero-positive dogs have no clinical signs.

Natural controls offered by the UK's island status are now under threat. Currently a derogation allows the UK, and four other EU member states, stricter controls to help maintain their Echinococcus multilocularis and tick-borne disease free status. It extends to July 2010 but comes up for review next year, pointed out Maggie Tomlinson from the Department of Health, who is taking the case to the EU Commission.

"I can say categorically that they are not keen for us to keep the derogation and it's going to be a very hard fight. We only have until January to push the Commission to make a decision."

Chairman-elect of ESCCAP Europe, James Duncan, pointed out the organisation is seeking to raise awareness of the serious risks posed by endo and ecto-parasites to human and animal health, and is developing independent guidelines and educational materials for their optimal control.

"There is no immediate panacea," he said. But those in the veterinary profession who are aware of the risks should take action. "It is up to you to lobby - put your voice to Government and influence the pet passport scheme. You can do that and it will help our cause because we are singing from the same hymn sheet."
