Quote:
"listeria is a sometimes deadly bacteria that is especially hazardous for
the very young and the very old. Pregnant women who become infected can have
miscarriages or stillbirths.
"Federal and state regulators, meanwhile, say they have very real concerns
about the safety of cheese, especially softer varieties like brie and
mozzarella that are more likely to harbor listeria.
My comment:
(a) The left column of the same web page directs readers to another report
written by the same journalist: As Cheesemaking Blooms, So Can Listeria.
The latter does not show up in the print. But it is interesting to read the
eight paragraphs about Mrs. McCool's operation, in a neigoboring town of
Washington state.
The rest of this report is similar to content of the feature report.
(2) The pathogen, Listeria monocytogenes, causes food-borne diseases--fatal
in rodents and USUALLY mild in humans (except in the newborns, teh elderly
and those whose immune system is compromised).

(3) "Responsible for approximately 2,500 illnesses and 500 deaths in the
United States (U.S.) annually,33,7 Listeriosis is the leading cause of death
among foodborne bacterial pathogens with fatality rates exceeding even
Salmonella and Clostridium botulinum."

(b) Reference 2 of
http://en.wikipedia.org/wiki/Listeria_monocytogenes
cites it but its link no longer functions.
(4) "Listeria monocytogenes can be cultured from approximately 5% of raw (
unpasteurized) milk samples * * * After reviewing these studies, a World
Health Organization Working Group on foodborne listeriosis recently
concluded that 'pasteurization is a safe process which reduces the number of
L. monocytogenes occurring in raw milk to levels that do not pose an
appreciable risk to human health.'"

MMWR stands for Morbidity and Mortality Weekly Report, which is published by
CDC.
(5) I am a biologist by training. I am a rebel, too. But oftentimes I am
utterly stumped by people (Americans and Taiwanese) who are irrational and
do not know what they are talking (in my view anyway).
Many an American insist in drinking unpasteurized milk.

My comment: Read the first two paragraphs.
