PermalinkSomeone is finally doing what should have been done at the beginning of
this dairy influenza fiasco, but they are not expanding their program
nationally as it should be implemented.
They are only going to assist the California contact tracing efforts and
have sent a team of 5 USDA staff members to "aid in traceback efforts
and epidemiological investigations". Nine more case managers are
supporting the effort to track and manage infected herds. This type of
program should be implemented in all states with known infected herds,
and likely states that have H5N1 in their waste water and or have
produced virus positive milk products in the FDA studies.
Part of the new National response is to start the type if testing of the
nations milk supply that the recent article by CDC researchers, where
they found that the most common pasteurization method may not kill the
virus, and they recommended that milk products should likely be tested
for viable virus in a more stringent testing regime than the FDA had
conducted. The USDA is going to conduct such a testing survey of the
nations milk supply. They need to start testing milk fresh out of the
processing plant within 4 days of pasteurization. My take is that they
should be sampling the milk as it comes out of pasteurization at all plants.
I should note that the CDC did not act on their own research on
survivability of the virus in milk, but someone has. It should be noted
that the first cats in Texas were infected by drinking raw milk, avian
influenza is a gut and respiratory infection in birds and has infected
the guts of the cattle causing decreased nutrient absorption of some of
the dairy cattle (their gut seem to shut down). The Missouri human
patient exhibited gut infection symptoms, and had, had no contact with
infected animals. She could have been infected by the milk supply. The
Missouri milk supply was not tested by the FDA. It was one of the
states that was not tested in their last milk survey (Samples collected
June 18th to July 31st). Missouri is just not testing their dairy
herds. They have never wanted to know if they had infected herds like
their infected neighbors, Kansas, Oklahoma, and Iowa. It is known that
asymptomatic cows can shed high levels of the virus in their milk (only
their mammary gland is infected), and that the infection can be limited
to only one of the four lobes of mammary tissue in the udder.
