Dice PANG (sin tildes, por pedido especial): Este es uno de los ultimos
reportes en lo concerniente a la enfermedad de las vacas locas, de la
que se habia comentado algo anteriormente. Solamente para re-enforzar el
concepto de que esta enfermedad se ve en los bovinos que practican
(involuntariamente) canibalismo. Es decir aquellos a quienes se les da
comida que contiene hueso molido, musculo, sistema nervioso central,
sangre, etc., de otros animales (bovinos). Es buena idea la de ser
vegetariano si uno vive en --o pasea por-- aquellos paises donde se
vende este tipo de carne (Ojo!, ClaudiaB y otr@s en el mercado
europeo!).

24 Sep 00 - CJD - New BSE outbreak linked to blood in feed Jonathan
Leake, Science Editor
Sunday Times ... Sunday 24 September 2000
Up to eight cows have contracted BSE in an outbreak that scientists
believe could be linked to the continued use of bovine blood in cattle
feed. The emergence of the disease has alarmed scientists because all
the animals were born after the 1996 introduction of measures that
should have eradicated BSE. Agriculture ministry officials had predicted
that no animal born after this date would become infected. Some
scientists have linked the latest casualties to the decision by
agriculture ministers to exclude cows' blood from the ban on using
material from cows in their feed. The practice has continued despite
warnings from senior scientists. John Collinge, the Medical Research
Council's professor of prion research and who has briefed Tony Blair on
BSE, said: "All cannibalistic recycling is potentially dangerous and I
have said that repeatedly."
Of the eight cows, one has been positively confirmed with BSE; the
others displayed symptoms of the disease and their carcasses are being
tested. The confirmed BSE cow was born in Devon in August 1996 and
records reveal that the farm was clear of meat and bone meal - the feed
suspected of spreading BSE. Agriculture ministry figures reveal that
22,000 tons of cow material, including blood, gelatin and tallow, are
fed to cows each year. A ban on the use of cows' offal, spines, bones
and brains in their feed has been rigorously enforced since 1996. Over
the past year, however, it has become increasingly clear that blood from
infected animals does carry prions. Some scientists on the government's
BSE advisory committee now believe that it is time to review the use of
blood in feed. A spokesman for Nick Brown, the agriculture minister,
said he was aware of the concerns and would consider any
recommendations.
