Animal Disease and Human Health Risk
Yersinia Enterocolitica Infection
Yersinia has the unusual distinction of being a common cause of unnecessary surgery. Many a
young person with Yersinia infection has undergone an appendectomy. The reason for this is
that the germ causes fever and severe lower abdominal pain that mimics acute appendicitis.106
Foods contaminated with Yersinia include pork, raw and pasteurized milk, chocolate milk, and
the Southern delicacy, chittterlings107 (made of pig intestines, known as "chitlins").
Clostridium Perfringens Infection
Clostridium perfringens is another common cause of food-borne outbreaks of infectious illness
in the United States. Usually, over 1000 cases are reported each year to the Centers of Disease
Control, but again, this is an underestimation of the actual cases.108 It is particularly
common when the food source implicated in the outbreak is cooked beef.109 In addition to beef,
chicken meat is also often infested with this germ. When infection develops, abdominal cramps
and vomiting are the rule, although the symptoms usually last less than 72 hours and
hospitalizations are unusual.
Beyond Upset Stomachs
It should be apparent that food-borne infectious illnesses can cause many problems beyond the
simple intestinal upset or diarrhea. As we have already seen, many of these germs can cause
life-threatening infections. Others can cause chronic crippling diseases. Campylobacter, as
we have noted, can cause Guillain-Barre syndrome that often cripples when it does not kill.
Salmonella can cause a chronic and permanent arthritis.
The fact is that more and more infectious diseases are being linked to chronic medical problems.
A new infectious link has emerged to an often-devastating incurable intestinal illness known as
Crohn's disease. Crohn's can cause such symptoms as bloody diarrhea, fever, severe abdominal
pain, arthritis, and incapacity, as well as obstruction of the intestines that requires surgery.
This disease up to now has had no known cause and has bewildered medical scientists for years.
I currently treat many Crohn's patients and although I have had success in controlling the
condition in most patients, the disease remains a lifelong one with no cure. Researchers
now have noted a link that at least some cases of Crohn's may be caused by infection with a
germ called mycobacterium paratuberculosis.110, 111 This organism is extremely common in
animals like sheep and cattle. The bacteria cause a chronic intestinal disease called Johne's
disease that affects approximately 25 percent of U.S. dairy cattle.112 One of the most
frightening aspects of this disease is that healthy-appearing cows can be infected and
transmit the germ in their milk. In one study of a heavily infected Ohio herd, over one
in four healthy-appearing cows had the germ in their stools and one in 12 had the germ in
their milk.113 These are particularly chilling statistics when you realize that the germ
can survive common pasteurization methods.114
