Why FMD is a bigger threat than Aus appears to recognise

Dr Ross Ainsworth, 28/06/2022

Q. What is the risk of transmission of FMD from Indonesia to Australia?

A. In my opinion the risk is extremely high over the next 1 to 6 months.

The last case of Foot and Mouth Disease (FMD) in Australia was recorded in 1872. Since that time Australia has managed to remain free of the disease through a combination of effective biosecurity arrangements, strict animal quarantine and a measure of good luck. Indonesia has been free of FMD since 1986 providing a significant “barrier” to the disease which has been endemic in mainland Asia for centuries.

Outbreaks in Asia are relatively common, certainly in the order of several per year but the disease tends not to be a major problem for these countries as they are largely protected by highly effective vaccination programs. None of these countries export meat so their industries are generally not significantly impacted. Outbreaks usually result from the movement of animals out of unvaccinated areas, such as Myanmar into areas of neighbouring countries where for various reasons vaccine use has lapsed.

Considering the long history of infection in Asia with no transmission to Australia, why does the current outbreak in Indonesia represent a new and heightened risk?

There are four major factors which combine to produce a much greater and more immediate threat of disease transmission from Indonesia to Australia:

  • The disease is spreading quickly through the Indonesian islands and will soon infect Bali;
  • As yet there are only very limited quantities of vaccine available to protect local livestock;
  • The main religion in Bali is Hindu which means that there are large numbers of pigs as well as upwards of 600,000 head of cattle spread all over the island;
  • Tourism is rebounding rapidly as the restrictions from the Covid 19 pandemic subside with large and increasing numbers of Australian tourists visiting Bali.

FMD is one of the most contagious of all animal diseases. Infected animals excrete virus into the air and through all secretions including saliva. Pigs are multipliers of the virus as they excrete up to 3000 times more virus into the environment than ruminants. FMD virus can be spread from animal to animal and by contaminated vehicles and equipment including footwear, hands and clothing. Signs of infection include fever, depression, reduced appetite, increased salivation, and lameness. Virus can be excreted from an infected animal up to four days before clinical signs are apparent. While the virus survives longer in the environment in cold temperatures, its survival is improved when it is enclosed in organic matter and the humidity is above 60pc. The humidity in Bali today is a little over 80pc and this is the “winter” or dry season.

With the advent of mechanical equipment for farming tasks, the primary role for Bali cattle is a store of value for their owners (see earlier Bali cattle article). The daily routine involves cattle being walked out from their secure overnight holding area to a location where they are tethered for grazing during the day. At about 5 in the afternoon the owners collect the animals and walk them home again where they are held in the secure location and provided with additional supplementary feed.

The photos below show Bali cattle in one of the main tourist areas of Seminyak.  Most of these cattle are very quiet so it is easy for anyone including tourists to approach them and pat them if they wish. They are stunningly beautiful animals, so it is not uncommon for tourists to approach them for close up photographs.

“Mouse” Sullivan frequently visits these cattle and their owners near his villa in Seminyak.

 

Much of the remaining land in the southern tourist areas of Bali is vacant blocks between tourist villas.

 

In the late afternoon these cattle are walked home through Seminyak passing tourist villas, local homes and small shops.

 

Bali cattle are generally very quiet and their owners are extremely friendly often allowing tourists to pat them and take photos.

 

This vacant block in Seminyak is the secure nighttime home for more than a dozen cattle which are taken out to graze every day.

 

It is not too difficult to image this bull leaving a trail of virus from early stage foot and mouth lesions as he walks home passed this tourist villa shortly before the tourist walks out to get into their taxi to leave for the airport (12km away) for their 2.5 hour flight to Darwin. Many Darwin residents live in the large rural area surrounding the city where there are many opportunities to come across cattle, buffalo and pigs. The virus can survive several days in organic matter on the bottom of shoes.

In mainland Asia where Australian tourism is also very common, national FMD vaccination programs are normal practice so the chances of a tourist encountering an infected animal excreting large volumes of virus are remote. Cattle ownership in the middle of other Asian tourist destinations tends to be much less than in Bali.

There are a wide range of estimates on what an FMD outbreak in Australia would cost the economy and they range from 15 to 80 billion dollars over a 4+ year period. Regardless of the number, the impact to the Australian economy in general and the livestock industries in particular would be immediate and catastrophic with ongoing trade restrictions continuing for many years.

Considering the magnitude of the impact of an outbreak of FMD to Australia and the dramatically increased risk presented by the current epidemic in Indonesian I believe that it would be appropriate to upgrade the biosecurity measures to match this increasing risk. Until Bali is fully protected by vaccination of its cattle and pig populations, an increase in the attention paid to tourists returning to Australia, especially their footwear, seems to me to be warranted.  Travelers are already used to a multitude of annoying Covid interventions so additional requirements such as ensuring that shoes are clean and walking through a wet sponge infused with disinfectant before boarding and after leaving the flight would seem to me to be simple and sensible measures which might help to address the new level of risk. A search of flights this morning shows that there are 13 direct daily flights from Bali to Australian capital cities. This will increase by at least double later this year. There is no need to restrict tourism to Bali, just reduce the chances that one unknowing traveler will cost Australia and its livestock industries $50 billion dollars not to mention the massive animal welfare implications. The risk will return to more traditional levels once Indonesia’s susceptible animal populations are fully protected by a comprehensive vaccination program.

    Don’t wait until it arrives in Australia. Livestock owners get off their arses and start vaccinating NOW. Also stop non essential travel to Indonesia including bogan tourists to Bali

    The distinct lack of mainstream coverage of this devastating threat to our island continent is not only complacent but hugely irresponsible. I cannot stress strongly enough about the importance of getting preventative measures in place with all the resources the nation can muster. A sustained information campaign over all forms of media is needed to inform the population of extra care measures that can help to keep FMD out is a must. Please pull out all the stops as this is one horrible assassin that is not welcome here.

    Govt. action needs to be immediate not just … we are looking into it! Many good points made below but nothing that gives rise to any confidence that AQIS, Border Force, DPI or Govt Ministers are ‘onto’ the severity of this threat. This will have ramifications through all sectors of the economy, yet the silence is deafening. Perhaps, farmers, truckies, agents, processors and others should consider the reaction of Dutch farmers to threats to their lively-hoods??!!

    Excellent paper !!

    This needs to be escalated to the highest priority by all forms of government and quarantine immediately

    • Robin Hansen, 01/07/2022

      Good morning Belinda, the responsibility for preventing the introduction of any exotic animal and plant disease is the responsibility of the Federal Department of Agriculture, Water and the Environment.

      Like all responsibilities this responsibility is shared by industry and the travelling public.

      Back in 2001 after the outbreak of FMD in the UK AQIS used footbaths to prevent the FMD virus entering Australia on passengers footwear. They were a primitive affair with passengers baulking at the troughs with some passengers attempting to jump the trough or take off their footwear and wade through the trough.

      There must be much more suitable, practical and discreet ways to disinfect worn footwear from FMD infected regions these days.

      Regards Robin.

    Just taking this simple step would also raise awareness among tourists of what is at risk for all Australians if FMD breaks out here.

  7. Peter Dunn, 28/06/2022

    It will take only one tourist, one single tourist. We should be well and truly past the point where Dr. Ainsworth is still having to warn the industry and governments.

  8. David Plumb, 28/06/2022

    This is a significant risk.
    Are we secure in our expectation that people will respond to government interventions which may inconvenience them or lower their income?
    Having just gone through Covid , the experience has educated the Australian public to so much about infectious disease but will essentially economic considerations affecting a small segment of society get the same respect?
    Pre Covid I would have thought so but the proliferation of diverse approaches during Covid was challenging.

  9. Harvey Carter, 28/06/2022

    Australia MUST ban all travel to or from Indonesia, NOW. This ban should remain in place until Indonesia is free of FMD.

    With the outbreaks of Foot and Mouth Disease, as well as Lumpy Skin, in Indonesia, only a stone’s throw away from our northern shores, it surprises me how little concern is being shown other than for the agro pollies of our red meat industries to write and chatter about what our biodiversity protocols should be on farms.

    Coming from Argentina, have been here for some fifty years, the memory of the disease and what we had to do back In the sixties to keep it at bay, it is shocking to see the lack of any form of effort to control what will be one of our worst carriers and spreaders, not if, but when FMD reaches our farms. I am referring to our exploding wild pig population.

    If we are at all serious about trying to stop its spread, I would suggest the use of our Defense Force personnel and their gun power as a much more effective measure than all the wasting of funding on committee building and chit chatter in our metropolitan centers. There is, I believe, precedence for this, when the ADF was used in Queensland some time back to stem the control of wild originally domestic cats.

    At the very least all our PP Boards, now LLS (Local Land Services), in NSW and their equivalent in the rest of the states and territories, should be funding and promoting the most rigorous of campaigns to try to at least minimize these populations of feral pigs, and any other foreseen carrier. Our environment would be greatly helped if foxes and cats were also on the extermination listing.

    I also would like to know whether animals like our kangaroos can contract and spread any of these diseases? Others that come to mind are goats, camels and donkeys, all of which abound in the outback.

    What are we waiting for? Tomorrow is too late.
