Solution for E.coli 0157:H7
in our water and food supply:
|
Introduction:
There are many problems facing our planet's water and food supply today.
This article will address one small but serious problem, namely, bacteria
and specifically E.coli in our water and food supply. We will discuss the
accepted origin of the bacteria and possible solutions in whole or in part
to help eliminate the problem at the source in a safe and natural way.
E.coli in our water and food supply
One of hundreds of strains of the bacterium Escherichia coli, E. coli
O157:H7 is an emerging cause of foodborne and waterborne illness. Although
most strains of E. coli are harmless and live in the intestines of healthy
humans and animals, this strain produces a powerful toxin and can cause
severe illness and death. It can be passed to the earth through manure
(including human, domestic, and wildlife feces). Manure can then contaminate
a water source.
The sources of human E.coli in surface water include raw and treated
sewage from sewage treatment plants and holding lagoons, septic system
seepage and illegal connections or dumping into streams and lakes.
An estimated 73,000 cases of infection and 61 deaths occur in the United
States each year. http://www.cdc.gov/ncidod/dbmd/diseaseinfo/escherichiacoli_g.htm
What is E.coli and it's Purpose
The GI tract of most warm-blooded animals is colonized by E. coli within
hours or a few days after birth. The human bowel is usually colonized within
40 hours of birth. E. coli can adhere to the mucus overlying the large
intestine. Once established, an E.coli strain may persist for months or
years. Resident strains shift over a long period (weeks to months), and
more rapidly after enteric infection or antimicrobial chemotherapy that
perturbs the normal flora. The basis for these shifts and the ecology of
Escherichia coli in the intestine of humans are poorly understood despite
the vast amount of information on almost every other aspect of the organism's
existence. The entire DNA base sequence of the E. coli genome has been
known since 1997. © 2002 Kenneth Todar University of Wisconsin-Madison
Department of Bacteriology
Escherichia coli or E. coli is a type of fecal coliform bacteria that
lives in all human and animal intestines. A minority of E.coli strains
are capable of causing human illness, which includes E.coli 0157:H7. E.
coli O157:H7 is one of hundreds of strains of the bacterium E. coli. Although
most strains are harmless and live in the intestines of healthy humans
and animals, this strain produces a powerful toxin and can cause severe
illness and death.
How long have we had problems with E.coli 0157:H7
E. coli O157:H7 was first recognized as a cause of illness during an
outbreak in 1982 traced to contaminated hamburgers. Since then, most infections
are believed to have come from eating undercooked ground beef.
However, some have been waterborne. In 1999, people became sick after
drinking contaminated water in Washington County, New York and swimming
in contaminated water in Clark County, Washington. In Walkerton On. Canada
seven people died and numerous were seriously ill after an E.coli outbreak
in their water supply. Though it may seem odd to think this way, it is
accurate to consider humans as individual ecosystems. E.coli is in the
gut of many species so it goes from the gut to the environment and then
back to the gut again through ingestion of contaminated food or water,
or through human to human contact with an infected person.
In November1998, the IBP beef processing plant in Dakota City recalled
more than half a million pounds of ground beef after a sample showed signs
of 0157:H7 contamination. Similar recalls involving millions of pounds
of ground beef in 1997 spurred the state Legislature to pass LB1206, which
appropriated $250,000 annually for five years to NU for E. coli 0157:H7
research. http://ard.unl.edu/rn/0399/ecoli.html
How does E.coli 0157:H7 get into our water and food
supply
E. coli comes from human and animal wastes. During rainfalls, snow
melts, or other types of precipitation, E. coli may be washed into creeks,
rivers, streams, lakes, or groundwater. When these waters are used as
sources of drinking water and the water is not treated or inadequately
treated, E. coli may end up in drinking water.
Problems with waste management do arise when the modern practice of
intensive livestock production of beef and pork is considered. Intensive
livestock production occurs in small areas, with large numbers of animals,
thus the fecal waste production per area is highly concentrated. Another
contributing factor to the high number of ecoli in the manure is the feeding
and management practice of many of these operations. In several farm trials
the simple addition of lactic acid, lactobacillus with plant extract enzymes
added to the existing rations lowered ecoli 0157 in the manure DRAMATICALLY.

Hog Trial #1
As human populations grow, the treatment of human fecal wastes will
become a larger environmental concern. If humans are considered as individual
ecosystems, as discussed above, then not only can organisms such as E.
coli move into us from the environment but it can also move out of us into
the larger environment. Therefore, the treatment of human sewage will be
of increasing importance.
In many rural areas, Walkerton included, sewage is treated through
the use of septic fields. While this system works well in low density populations,
there is potential for groundwater contamination. In most urban areas,
sewage is pre-processed before being released into the environment so that
the biological activity within the sewage is eliminated and most toxins
are removed. http://www.med.uwo.ca/ecosystemhealth/education/casestudies/walkertonenviro.htm
How does food become contaminated with E. coli?
Food can become contaminated at several points before it reaches our
mouths. It can be contaminated by incorrect slaughter procedures, crop
fertilization, washing with contaminated water, or unhygenic food preparation.
Slaughter Management
Ground beef is a significant source of infection because of livestock
feeding as well as meat handling procedures. E. coli O157:H7 has been detected
in the intestinal samples of 1% of healthy cattle. When the cattle are
slaughtered, there is some opportunity for intestinal contents to contact
other tissues. Even if just a small portion is contaminated, it is easily
spread throughout the tissues by the grinding process. If properly cooked,
there is no danger of infection, but a lot of people enjoy their hamburgers
a little pink on the inside. When incompletely cooked, the bacteria survive
and infect. Because the meat of many carcasses is mixed in the production
of ground beef, it only takes a few cattle to be infected to contaminate
a large amount of meat (Boyce et al, 1995). http://www.med.uwo.ca/ecosystemhealth/education/casestudies/walkertonenviro.htm
Fertilization of Agriculture Crops
The most common ways for produce to become contaminated with E.coli
are; contact with fecal material through fertilizer use, and contact with
contaminated water. Fecal wastes from livestock production are used as
fertilizers in agriculture. If produce is not sufficiently washed before
human consumption, then E. coli infections can result.
How do humans contribute to E. coli outbreaks through environmental
manipulation?
Throughout human history the natural environment has been altered for
the benefit of humankind. Only with the increase in population in the past
few centuries have these alterations begun to cause serious negative repercussions.
The increasing incidence of E. coli outbreaks is one such result. Humankind
has manipulated the environment in several ways which may contribute to
E. coli outbreaks such as the one in Walkerton, Ontario, for example: the
intensification of livestock operations, the close proximity of dense populations
of livestock and humans, and the intensification of agriculture (crops).
http://www.med.uwo.ca/ecosystemhealth/education/casestudies/walkertonenviro.htm
How can we stop E.coli 0157:H7 from being found in
the water, food supply, manure, livestock intestines
Most of the available information and research deals with problems
once the E.coli has migrated from the intestines of animals into the environment.
There are methods in the feeding procedures that could lessen bacteria
in the manure, on the land and in the water supply. Research is underway
for vaccinations against the bacteria but there is little research
being done on the source and nature of the flora and fauna in the intestines
of ruminants and monogastrics and how to work with it in a natural way.
What precautions have been taken to prevent E.coli
0157:H7 from entering our water and food supply?
Many local municipalities have created by-laws governing storage and
application of livestock manure. There are a number of researchers proposing
various procedures to deal with the problem of E.coli 0157:H7 in
our water and food supply. Government legislation, Environmental Protection
Acts, Water Resources Acts, the Farming and Food Protection Act all have
proposals, procedures, legislation, etc, to address E.coli 0157 but little
has been done to understand how the changing of the terrain or the environment
of the gut is altered in a healthy way by using fully effective probiotic/enzyme
products.
Questions one should ask!
What is the terrain of the Intestinal Tract (IT) consist of.
What is the nature and purpose of bacteria in the terrain of the Intestinal
Tract (IT)?
What are the differences between friendly and unfriendly bacteria and
how does nature deal with this in a healthy body?
Where does E.coli 0157 and other unfriendly bacteria originate and
can friendly bacteria (probiotics) counteract them through competitive
exclusion?
Why is this not known in the scientific world?
Common sense; can simple good sense help in the
prevention of these problems?
It is becoming more and more apparent that we just can not wait
until science has the time, money or interest to pursue certain problems
facing our world. Sometimes complex problems require simple solutions.
In our headlong rush toward progress we have spared no expense, which is
to say we have attempted to further our immediate needs at any cost. Good
old fashioned common sense would indicate that:
A healthy body has numerous friendly bacteria naturally resident in
the Intestinal Tract (IT).
These organisms are vital to the healthy processing of food and nutrients
in humans and animal's.
The vitamins, minerals, proteins and other nutrients, thus processed,
determine the health of the body.
It stands to reason that we need a constant supply of friendly or probiotic
bacteria in the IT to maintain a healthy body.
It stands to reason that anything that inhibits this healthy fauna
and flora in the IT will eventually cause disease. eg antibiotics
It should be obvious that the gut needs to be replenished with friendly
bacteria on a constant basis
Can probiotics help to eliminate E.coli 0157 in the
Intestinal Tract
V63/II
Reduction of Escherichia coli 0157:H7 in dairy cattle by selected probiotic
bacteria
Tong Zhao, Michael P. Doyle, Barry G. Hannon, and Cathy A. Brown
Center for Food Safety and Quality Enhancement, Department of Food
Science and Technology and Department of Pathology, University of
Georgia, Georgia, USA
Fifteen cannulated calves were studied to determine the efficiency of
selected probiotic bacteria in reducing/eliminating carriage of E. coli
O157:H7
(O157). Of 9 control calves administered O157 only, O157 was detected
intermittently in rumen samples of all animals throughout 3 weeks
post inoculation, and was shed at various levels in feces continuously
throughout the experiment (mean 28 days). O157 was isolated from the rumen
and
colon of 8 of 9 and 9 of 9 calves, respectively, at the termination
of the study. Six calves received orally probiotic bacteria (1010CFU) followed
2 days
later with O157 (1010CFU). O157 was detected in the rumen for only
9 days post inoculation in two animals, for 16 days in one animal, for
17 days in two animals and for 29 days in one animal. O157 was detected
in feces for only I I days post inoculation in one animal, for 15 days
in one animal, for 17 days in one animal, for 18 days in one animal, for
19 days in one animal, and 29 days in one animal. Results indicate that
selected probiotic bacteria can reduce the carriage of O157 by cattle when
administered before exposure to O157.

Swine....Hog
Trial #1 - Efficacy Testing of EnzoLac
Results of Manure Testing for Salmonella and E.coli done by Agri Foods
Labs.
The EnzoLac Group of Hogs was 0.0 C.F.U. (Colony Forming Units) for Salmonella
and 90,000 C.F.U. for E.coli.
The competitor was 0.0 C.F.U. for Salmonella, but was 2,000,000 C.F.U.
for E.coli.
Testing of EnzoLac - Poultry
Research Study - May 23, 2002 to June 27, 2002
Why is the agricultural community, our governments,
the public and business largely unaware of these issues?
(what do you think)
Where can we get these products of probiotics?
Bio-ag is the manufacturer of the only organically registered Probiotic
in America (as far as we know) EnzoLac.
EnzoLac is a probiotic livestock feed supplement.
EnzoLac is a microbial growth stimulant manufactured by using a special
patented fermentation process, which produces this lactic acid, lactobacillus
fermentation probiotic. Specific live plant enzymes (Kreb
Cycle) are then added on a GMO free (genetically modified organisms)
wheat carrier to enhance the efficiency of the probiotic and to create
a balance in the digestive system to ensure optimum health and productivity.
Inquire
for pricing and information.
Conclusion
The presence of E.coli 0157:H7 in our water and food supply
has its source in the IT (Intestinal Tract) of livestock and humans. Probiotics
can greatly reduce the risk of unfriendly bacteria including E.coli
0157:H7 in the IT. We need much more research in this relatively unknown
terrain of the animals anatomy, but with what research we have it is clear
that the regular use of probiotics makes intelligent good sense. The thing
to remember is that many of these probiotics even while they have high
counts do not survive stomach acids. EnzoLac is one of the few in
the market place that can proudly state that it is a survivor.
