Pig industry moves to red alert over transatlantic killer
The British pig industry is on red alert, in a bid to prevent an outstandingly virulent pig
disease from entering the country. Until more is known about transmission routes of
porcine epidemic diarrhoea virus, the industry is focusing in particular on a specialist
feed ingredient for young pigs—spray-dried porcine plasma.
Positive polymerase chain reaction tests in the States and bioassay tests by the Canadian Food Inspection Agency have pointed to spray-dried porcine plasma (SDPP) as
an ingredient being capable of containing porcine epidemic diarrhoea virus (PEDv), but
not that it is necessarily capable of actually transmitting the disease. Further tests are
ongoing in the hope of getting a clearer picture.
But specialist pig vets say that if PEDv arrived in Britain it would spread quickly through
the nation's naive pig population, causing incalculable damage, so industry organisations are urging producers to take every precaution, even though the case against
SDPP is unproven.
BPEX, National Pig Association, Pig Veterinary Society, the Agricultural Industries
Confederation and British Pig Association have joined forces to keep PEDv out of the
country.
All pig producers are being urged to work with feed manufacturers, nutritionists and
vets to identify and immediately isolate any feed products on farms that are labelled as
containing SDPP.
SDPP is banned by Red Tractor assurance, which regulates over 90 percent of the nation’s domestic pig supply. However it may be present in a few milk replacer and milk
blend products, without producers necessarily being aware of the fact.
PEDv is harmless to humans but is killing up to 100 percent of piglets on affected pig
farms in the United States. Nobody knows how the highly infectious virus spread to the
States from China, and how it has subsequently spread to Mexico and Canada.
To help producers make the safest choices, National Pig Association and BPEX will be
publishing on their respective websites a list of manufacturers that guarantee all their
products, particularly milk replacer and milk blend products, are entirely free of SDPP.
BPEX and NPA are also reminding producers that they should only use feed that is
monitored by UFAS, the animal feed assurance scheme.
“It is impossible to overstate the damage PEDv would cause if it arrived in Britain,” said
veterinarian Derek Armstrong, of BPEX. “The evidence from the States is that it is so
outstandingly infectious that just one infected pig is all it would take to start an epidemic in this country which could kill as much as ten percent of the national herd.”
NPA chairman Richard Longthorp said, “We are clear that we don’t want to be looking
back in a few months, and wish we had been more cautious. We are all agreed in the
pig sector that we should close off every avenue of risk and potential risk for the time
being.”
Current estimates suggest that in the United States alone PEDv could kill as many as 5
million piglets before the national herd starts to develop antibodies against the virus,
equivalent to 4.5 percent of all pigs sent to slaughter.
In addition to the question mark over SDPP, the virus can spread rapidly through contact with sick animals, as well as through people's clothing, hands, equipment, boots,
and tools contaminated with the faeces of infected animals.
