More evidence that Mad Cow and other infectious prions may be in milk was found by Dr. Adriano Aguzzi, one of the world's leading prion researchers
based at the Institute of Neuropathology at University Hospital in Zurich, Switzerland. Aguzzi and his team found prions in the mammary glands of
co-infected sheep, and in macrophages - cells used by the immune system to try to clear infection. Reports Aguzzi, "It turns out that if you have an
inflammation of the mammary gland, the milk is full of macrophages. So it's not hard from there to infer that eventually you will end up with prions
in the milk."

New research into prions, the infectious agents that cause mad cow-like diseases, has found them in the mammary glands of some sheep, raising
questions about whether milk and milk products from infected animals could transmit the pathogens. ...prions (are) highly infectious misfolded
proteins...
"I think the public health implications of this are profound . . . (and) need further investigation," Dr. Neil Cashman, Canada's leading expert on
transmissible spongiform encephalopathies or TSEs, said Thursday. ...The findings were reported by a team of scientists led by Dr. Adriano Aguzzi, one
of the world's leading prion researchers.
...His team had earlier shown that prions, once thought to be concentrated in the brain and central nervous system tissues of infected animals,
actually migrate to other organs if those organs are inflamed because of infection. ...In a study published in January, they showed prions migrated to
and propagated in the pancreas, kidney and liver of infected mice when inflammation of those organs was induced. Earlier this fall they showed that
mice co-infected with a prion disease and inflammation of the kidneys shed prions in their urine.
Prions were found in the mammary glands of co-infected sheep and in macrophages - cells that the immune system uses to try to clear infection - those
sheep generated, Dr. Aguzzi said in an interview from Zurich. ..."It turns out that if you have an inflammation of the mammary gland, the milk is
full of macrophages. So it's not hard from there to infer that eventually you will end up with prions in the milk," he said.

It is hard to find online media coverage of this important study. Nature Magazine classifies it as a "Premium" offering: not even an abstract is
available to the public. A Google search brings up Canadian coverage in smaller papers - but nothing from the USA or anywhere else. A direct search of
the BBC is fruitless; there are no articles about milk and prions. Apparently our corporate rulers have decided that this information's threat to
industry is more important than Mad Cow's threat to peoples' health.
This is not the first time researchers have linked Mad Cow and other infectious prions to milk. It's just the latest attempt to make the information
public.
For example:
According to the EU's food safety authority EFSA, dairy products made from goat's milk would be
unlikely to pose a risk for human health if the milk came
from a healthy animal.

In both VRQ/VRQ lamb groups, PrP(Sc) spatial and temporal accumulation patterns were similar, suggesting
post-natal rather than in utero contamination (by Mad Cow-like scrapie
prions).
On PubMed
Ed. note: "post-natal" meaning via mother's milk.
...PrP(Sc) was detected only in susceptible VRQ/VRQ sheep, from 2 months of age, with an apparent entry site at the ileal Peyer's patch as well as
its draining mesenteric lymph node.
Early accumulation of PrP(Sc) in
gut-associated lymphoid and nervous tissues
Ed note: the "entry sites" again indicate transmission via mother's milk.

For decades, scientists have been warning authorities that Mad Cow and H5N1 bird flu are spreading, and mutating. They recommend prevention through
clean-up and animal quarantines.
But authorities would not act, or allow the public to be informed. They
say they want to prevent panic, and protect the economy. More bull
puckey. Government is managing the Mad Cow and prion disease crisis the same way they're handling the bird flu crisis - to protect international
corporate industry.
It's all about money: profits before people. In point of fact, Mad Cow doesn't cost
industry anything,
unless the public knows what's going on.
Clean-up and prevention was still possible even three months ago. Now, it may not be.
So authorities plan to quarantine infected people - instead of quarantining animals to prevent Mad Cow's and H5N1 bird flu's spread and mutation.
