- Hello Jeff - Again, we are given the reassurance that
there is "no evidence of risk for humans."
- "At present there is no evidence to suggest a risk
to humans, but scientists are not ruling it out."
- The "disease" affects the white matter of the
brain which leads to paralysis and death. As to what virus, IF viral agent,
is involved, remains a mystery.
- "In layman's terms, a type of cattle polio was identified
which we haven't seen before."
- My question arises," is it a virus causing this
cattle polio?" Could this be related to mad cow disease? Is there
a pollutant or mycoplasma/spiroplasma/or spirochete triggering the destruction
of the white matter in the brain.
- IF humans consume meat, especially that which could contain
CNS material, will humans contract the disease?
- Recently, we have heard of mutating prion disease such
as mutated or atypical scrapie, BSE etc etc. We have also learned of a
strange mystery illness that killed Elk in the US. Is there any relation
to this polio-like illness in cattle?
- I wonder how many (downer) cattle with this illness have
"slipped" through the slaughterhouse gate and entered the pet
food chain, or worse, the human food chain?

- Cow Death Sparks Virus Risk Probe
- The mystery death of a cow in Cumbria [in England, just
south of the Scottish border. - Mod.JW] has sparked a government investigation
into any virus risk to humans. State vets are also examining the unexplained
deaths of a further 20 animals as "a matter of urgency". The
alert was triggered by the death of a milking heifer at a farm in Cumbria
late in 2003.
- The government's deputy chief vet, Frank Landeg, said
the Health Protection Agency is looking into whether humans could be at
risk. Mr Landeg said experts had been looking for any possible human link
to the polio-like virus since the milking heifer died before Christmas
- The animal's death could not be put down to any known
cattle disease and has sparked concerns that an unknown condition could
be in circulation. Tests on the heifer were carried out at the government's
veterinary laboratory in Penrith.
- It is thought a virus may be responsible for the condition,
described as a type of cattle polio. But, so far, tests for various known
bovine diseases have all proved negative. At present there is no evidence
to suggest a risk to humans, but scientists are not ruling it out.
- It is thought the brain disease vCJD originally passed
to humans from cows infected with the closely related condition BSE.
- Analysis of this cow's brain showed that the disease
affected the white matter. This led to paralysis for 5 to 6 days, followed
- Mr Landeg defended not making details of the investigation
public earlier. He said: "It does take time to put together a group
to look at this, bearing in mind what we are talking about here is a possible
examination of significance to man. "There is a great deal of uncertainty
- A spokesman from the Department for Environment and Rural
Affairs (Defra) said the case was being carefully investigated. He said:
"The Veterinary Laboratories Agency (VLA) have recorded possibly a
new condition in cattle in the UK. "In layman's terms, a type of
cattle polio was identified which we haven't seen before."
- The animal was tested for a battery of diseases, all
of which proved negative. The spokesman said no meat from the animal had
been allowed into the food chain.
- Mr Landeg added: "The fact is that we do not know
whether there is any significance for man, because we have not been able
to isolate a causal agent."

- [This news item includes some additional information,
such as the location and timing of the initial disease incident and the
possibility - - yet to be substantiated -- of similar cases in the past.
- 2 statements need clarification: on the one hand, a "polio-like
virus" is mentioned; on the other hand, it is stated that "no
casual agent has been isolated". Can it be speculated that a "polio-like"
virus, the etiology of which not yet established, has been detected by
electron-microscopy? - Mod.AS]
