A record number of people in Dallas County [Texas] have been sickened
from an infection caused by consuming unpasteurized cheese, health
officials said. There have been 13 brucellosis infections in residents
so far in 2016, affecting patients between 6 and 80 years old,
according to a health advisory notice released on Thursday, 15 Sep
2016.

All of the patients reported eating cheese brought into the USA from
Mexico by friends or relatives, consuming the cheese while traveling
in Mexico, or eating unidentified cheese products from local street
vendors, officials said. The county typically sees 2 to 6 cases a
year, though 11 were recorded in 2004.

Health officials confirmed all the Dallas County cases by blood
culture. In 2 instances, hospital lab personnel were exposed while
handling the samples.

The brucella bacterium can infect livestock and is most commonly
transmitted to humans who consume unpasteurized dairy products. Some
areas, such as Mexico and Central and South America, are considered
high-risk, according to the Centers for Disease Control and
Prevention.

Proponents of raw milk products say it's more natural, tastes better
and has health benefits. But many state and federal agencies are less
keen, saying it can lead to more foodborne illnesses, such as
listeriosis. A listeria outbreak at Brenham [Texas]-based Blue Bell
Creameries in 2015 sickened 10 people and was linked to 3 deaths.

While legal in Texas, raw milk may only be sold at the dairy. State
Rep Dan Flynn, R-Van, drafted a bill in 2015 to allow people who
produce raw milk or raw milk products to sell directly to consumers at
their homes or farmers' markets. Sale at supermarkets would have
remained against the law. The bill failed to pass.

Symptoms of brucellosis include fever, fatigue, weakness, weight loss,
night sweats and headaches. Antimicrobials are used to treat the
infection, and recovery can take weeks to several months. While rarely
fatal, some people can also develop chronic or severe conditions. The
American Academy of Pediatrics has warned that pregnant women and
children should not consume raw milk or raw milk products.

[In the March 2012 issue of Emerging Infectious Diseases (Langer AJ,
Ayers T, Grass J, et al. Nonpasteurized dairy products, disease
outbreaks, and state laws -- United States, 1993-2006. Emerg Infect
Dis. 2012; 18(3): 385-91
<http://wwwnc.cdc.gov/eid/article/18/3/11-1370_article>), the authors
report on 121 foodborne outbreaks (with 4413 cases of reported
illness) caused by contaminated dairy products, and 73 (60 per cent)
were associated with unpasteurized dairy products. 65 (54 per cent)
involved cheese (42 per cent made from unpasteurized milk) and 56
involved fluid milk (82 per cent involved unpasteurized milk). In
these outbreaks, _Campylobacter_ spp were responsible for 54 per cent
of the outbreaks, followed by _Salmonella_ spp (22 per cent),
enterohemorrhagic _E. coli_ (13 per cent), _Brucella_ spp (4 per
cent), listeria (4 per cent), and _Shigella_ spp (3 per cent).

Clearly, pasteurized milk can also transmit disease, and 48 outbreaks
were reported. The source of contamination was reported in only 7 (14
per cent), of which at least 4 resulted from post-pasteurization
contamination by an infected food handler.

The reader is directed to the article for additional information and
discussion.

Classical zoonotic organisms such as _Brucella abortus_, _Brucella
melitensis_, _Mycobacterium bovis_, _Salmonella_ spp, _Listeria
monocytogenes_, _Campylobacter_ spp, _Yersinia_ spp, _Coxiella
burnetii_, and _E. coli_ O157:H7 are associated with the ingestion of
raw milk. Non-zoonotic organisms such as _Streptococcus pyogenes_,
_Salmonella_ Typhi, _Corynebacterium diphtheriae_, _Shigella_ spp,
_Salmonella_ Paratyphi A, _Salmonella_ Paratyphi B, enterotoxins from
_Staphylococcus aureus_, and hepatitis A have also been associated
with the ingestion of raw milk.

The following
(<http://www.foodsafetynews.com/2016/...-bacterial-diversity-in-californias-raw-milk/>)
is a recent report involving the bacterial diversity of raw milk
(interestingly the classical Enterobacteriaceae such as _E. coli_,
salmonella and campylobacter were not found):

"Researchers at the University of California-Davis report that samples
of raw cow's milk shipped by tanker truck for processing show 'amazing
bacterial diversity' which varies by season. Their findings were
reported [23 Aug 2016] in mBio, the online, open-access journal of the
American Society of Microbiology. The researchers sampled and analyzed
raw cow's milk from 899 tanker trucks as they arrived at 2 dairy
processors in California's San Joaquin Valley during spring, summer
and fall. The samples were analyzed using gene sequencing. This
collection included 229 tankers filled in the fall of 2013 and another
264 and 406 tankers filled in the spring and summer of 2014,
respectively. The larger set of samples collected in the summer
included milk collected from 2 sampling dates a week apart.

'The level of bacterial diversity that we discovered in these
shipments of raw milk was amazing,' said lead author and
microbiologist Maria Marco, an associate professor in the UC-Davis
Department of Food Science and Technology. 'More than half of the
bacterial groups identified represented less than 1 per cent of the
total microbial content.' She said the broad mix of bacteria could be
due to raw milk's high nutrient content, as well as the many potential
sources of bacteria associated with dairies. These include bacteria
from the cows' skin, feed, bedding and aerosols, and from human
handlers and the equipment and containers used to collect, store and
transport the raw milk.

Raw milk is known to harbor diverse strains of bacteria that strongly
influence shelf life, sensory qualities and safety of fluid milk, as
well as that of fermented dairy products such as cheese and yogurt.
While pasteurization of raw milk kills microbes which can cause
disease in humans, not all bacteria and their associated enzymes are
eliminated in the process. The remaining bacteria can still cause
spoilage and quality defects in dairy foods.

Researchers found that a 'core community' of microbes remains constant
throughout the seasons and across farms where the milk is collected.
This core community represented 29 different bacterial groups and
included high proportions of streptococcus and staphylococcus, as well
as Clostridiales, bacteria frequently associated with dairy cattle.
The study revealed that milk collected in the spring contained the
most diverse bacterial communities with the highest total cell numbers
and highest proportions of Actinobacteria (such as actinomyces and
streptomyces), one of the largest known groups of bacteria. The group
includes some pathogens.

Researchers also found that the bacterial composition of raw milk
stored in silos at processing plants was distinct from that of the
tanker trucks. One group of silos contained microbial populations
similar in makeup to the milk from the tanker trucks, while the other
group of silos had distinctly different microbial populations
dominated by acinetobacter and lactococcus bacteria.

'This finding demonstrates how the built environment in
food-processing plants can have significant but still unpredictable
impacts on the microbial quality of foods,' Marco said.

Identification of these raw milk microbes and their abundance should
help dairy processors develop new and more effective sanitation
procedures and process controls to make sure the milk and resulting
dairy foods are safe and of consistently high quality, according to
the report." - Mod.LL

I drink real milk every day and have for years. I've never met anyone who got sick from drinking real milk. All the laws were written to regulated the new fangled Pasteurized milk and then turned on there head by bureaucrats trying to protect big dairy with there unhealthy confinement herds.
