INTEGRATED SALMONELLA MANAGEMENT
2SALMONELLA OVERVIEW
Dr. D.E. Salmon, an American bacteriologist and
veterinarian, was first to isolate Salmonella in
1885.
Salmonella grow best at temperatures above 10o C
in environments with a pH range of 6-7.5.
Salmonella are facultative anaerobes classified
as genus three in the Family Enterobacteriaceae.
Salmonella is a food poisoning organism that,
under proper conditions, grows at extreme fast
rates often doubling populations within 15
minutes.
20 million people worldwide are infected yearly
by Salmonella resulting in approximately 500,000
deaths.

4SALMONELLA OVERVIEW
Non-pullorum salmonella serotypes, such as
typhimurium, enteritidis and heidelberg, are the
causative bacterial agents in most cases of
reported food poisoning.
In 1989, England and Wales reported 30,000 cases
with 61 deaths. About 45, 000 cases occur
annually in North America, but with a lower
mortality rate (Toman, 1990).
Economic losses due to salmonellosis in the USA
are estimated to be in excess of US1 billion and
possibly as much as 4 billion largely as the
consequence of lost wages, cost of medical
treatment and decreased productivity (St. Louis
et al., 1988).
5Salmonella enteritidis
Common Symptoms
In most cases poultry eggs are the culprit.
Illness lasts 4 to 7 days, most persons recover
without antibiotic treatment.
In some cases, diarrhea can be very severe enough
to require hospitalization.
The elderly, infants, and those with impaired
immune systems may be affected severely. In
these patients, the infection may spread from the
intestines to the blood stream, and then to other
body sites and can cause death unless the person
is treated promptly with antibiotics.
Symptoms are usually fever, abdominal cramps, and
diarrhea beginning 12 to 72 hours after consuming
a contaminated food or beverage.
6Salmonella typhi
S. typhi is the causative agent for typhoid
fever in humans, the most severe type of
Salmonellosis .
7Salmonella typhimurium
Less severe forms of gastrointestinal illnesses
such as diarrhea are caused by many Salmonella
strains and are collectively known as
salmonellosis.
One such strain is S. typhimurium which is able
to invade the epithelial cells of the intestinal
tract, survives the intracellualr defense
mechanisms of the host cell, and multiplies.

11APPROACH I
I. MANAGEMENT PREVENTION FACTORS
12PURCHASING PRACTICES
- Use reliable suppliers (GMP)
- Use suppliers who adhere to industry guidelines
published in by the U.S. Department of
Agriculture for poultry animal and fish products.
- Visit and observe the operations of suppliers.
- Approve as suppliers only those firms who follow
good practices and can routinely provide
Salmonella-negative ingredients
- Add DINASAL Liquid to purchased meat meals, fish
meals and soybean meals at a minimum dose level
of 2 kg per metric ton.
13INGREDIENT GUIDELEINES
- Purchase ingredients only from approved
suppliers.
- Transport ingredients in vehicles that are
clean, dry, and free from conditions conducive
to Salmonella contamination.
- While en route and at all other times, keep
ingredients dry and protected from insects,
birds, rodents and other animals.
- Upon arrival Inspect incoming ingredients for
evidence of water damage and for signs of fecal
contamination by insects, birds, rodents, or
other animals.
- Reject questionable material.
- Follow a program of periodic laboratory testing
of ingredients to monitor for the presence of
Salmonella.
14GUIDELINES FOR PLANT PREMISES
 Keep premises clean. Follow good housekeeping
and good sanitation practices. Continually
maintain control in and around the plant premises
. Prevent insects, birds, rodents, and other
animals from gaining access to or remaining in
the feed mill.
. Keep areas within and around the mill free from
refuse and trash.
. Store unused equipment in a manner to
discourage infestation.
. Keep the grounds surrounding the mill well
drained and free of unnecessary or undesirable
vegetation, such as weeds and high grass.
. Avoid unnecessary foot traffic from outside
sources in all mill areas. Salmonella may be
carried on the feet.
 . Pay particular attention to foot traffic from
such areas as barns, stock pens, and stock
trucks to all mill areas. This includes
employees who care for or raise livestock or
poultry.
 . Provide for sanitizing of footgear. DINATEC
recommends the use of Dinaxine, our stabilized
Chlorine Dioxide Solution at 10 ppm for footwear
disinfecting pans.
15GUIDELINES FOR EMPLOYEE FACILITIES
- Salmonella organisms can be carried on
clothing, shoes, or person.
- Provide adequate facilities for washing,
showering, and dressing .
- Instruct and train employees to maintain a high
degree of cleanliness of self and work clothing.
16GUIDELINES FOR PROCESSING AND STORAGE AREAS
- Avoid accumulations of dust, spillage, and
broken bags. Dispose of any material suspected
of having become contaminated with Salmonella as
waste unless analysis is negative for
Salmonella.
- Dispose any wet material as waste.
- Separate ingredients and finished feeds in the
storage area. Prevent air contamination by dust
circulating from raw ingredient areas to
processed material areas.
- Keep portable equipment used for handling
ingredients separate from that used for finished
feeds. Segregate dirty areas from clean areas.
17GUIDELINES FOR PROCESSING EQUIPMENT
- Construct bins, blenders, mixers, conveyors, and
baggers to minimize buildup or caking of
material and to provide access for inspection
and cleaning.
- Avoid accumulations and excessive buildup of
feed materials.
- Clean magnets at regular intervals to prevent
feed materials from building up at these points.
- Inspect equipment at regular intervals
- Clean equipment regularly to remove
accumulations of material.
- Construct and install all processing and
handling equipment in a manner to minimize
leakage, spillage and dust accumulation.
18GUIDELINES FOR PACKAGING, STORAGE AND
TRANSPORTATION
- Do not reuse previously used bags or containers
for packaging. New bags are generally
considered to be free of Salmonella
contamination.
- Make a continuing effort to minimize storage
time of ingredients and finished feeds.
- Insure that equipment used to transport
ingredients and finished feeds be clean, dry,
and free of conditions conducive to Salmonella
contamination.
19GUIDELINES FOR DUST CONTROL
- Provide adequate air filtration equipment for
the pellet cooler.
- Draw air from a clean area inside or outside the
mill to prevent recontamination.
- Periodically control and remove accumulated dust
that settles in processing and storage areas.
- Install a proper dust collector system to
control dust and to aid in keeping the mill
clean.
- Periodically remove settled dust with a vacuum
cleaner equipped with a highly efficient filter
rather than sweeping.
- Avoid using compressed air to remove dust from
equipment or from clothing of personnel.
- Destroy accumulation from the dust-collector
system and "sweepings.
20GUIDELINES FOR AIR CONTROL
 Avoid contamination of ingredients and finished
feeds via airborne organisms
- Do not draw air into the mill from areas likely
to be contaminated.
- Pay special attention to intake for air used
for cooling of pelleted or extruded products.
These products will normally be Salmonella
negative as a result of the temperatures and
pressures involved in these processes.
21GUIDELINES FOR MOISTURE CONTROL
Salmonella require moisture to multiply.
- Keep feed materials dry at all times.
- Keep roofs and ceilings leak-proof.
- Construct storage-area walls and floors in such
a manner as to keep out moisture.
- Avoid or correct conditions conducive to the
formation of condensation in buildings and
equipment. Poorly insulated pipes in the
receiving area of the feed mill can result in
condensation which will contribute to the spread
of bacteria
- Keep ingredients, finished products, containers,
storage areas, and transporting vehicles as dry
as possible will prevent growth of Salmonella.
22GUIDELINES FOR PROCESS CONTROL -
PELLETING Â Temperatures reached in pelleting are
critical in Salmonella control. A few seconds at
180 degrees F or twenty minutes at 165 degrees F
will usually kill Salmonella organism. While
these may be the target or intended temperatures,
they may not be reached at the beginning of the
process. For this reason, it may be necessary to
recycle the first material coming through the
system. Pellet mill must be carefully monitored
to insure proper operation with respect to
temperature.
23GUIDELINES FOR SAMPLING AND ANALYSIS
Results of laboratory examinations indicate
adequacy of purchasing, handling, processing, and
storage practices in procuring and producing
Salmonella-negative products.
- Secure samples of ingredients upon arrival at
the mill and of finished feeds at time of
shipment.
- Routinely subject samples to appropriate
physical examination for overall quality and
condition.
- Employ aseptic techniques in securing and in
handling samples of ingredients and finished
feeds that are to be analyzed.
- Use sanitized equipment and sanitize equipment
between samples. Periodically submit
representative samples of ingredients and
finished feeds for laboratory examination.
- When sampling a previously loaded vehicle or
material in storage, take a tablespoon or more
from each of 10 different locations.
24GUIDELINES FOR SAMPLING AND ANALYSIS
This sampling and analysis plan can be used as a
guide or starting point for the establishment of
a quality control monitoring program for
Salmonella
- Consider potential incidence and level of
contamination, composition, form, and the
various treatments to which the material has
been subjected.
- Total sample should weigh about half a pound.
- Bulk shipments- Sample at varying intervals of
time as material is unloaded or loaded
- Packaged material- Take minimum 1 tablespoonful
from each 20th 100-pound bag or each 40th
50-pound bag.
- Categorize product as to whether it is
homogeneous or heterogeneous in nature.
- Place samples in a new or clean, secure sterile
container.
- Label and identify container and mail
immediately to the laboratory.
Salmonella-negative ingredients and finished
feeds are defined as those in which Salmonella is
not detected when sampled and analyzed by the
procedures outlined in these guidelines. No
sampling plan will fit everyone's or every
product's requirements.
25CRITERIA FOR LABORATORY SELECTIONS
Analysis for Salmonella is a procedure normally
requiring use of a commercial laboratory.
Selection of a competent laboratory is essential
for confidence in the results.
. Use FDA or AOAC recognized procedure.
. Allow no variations to the recognized
procedure.
. Utilize positive/negative controls.
. Confirm tests by using alternate tests
. Specify sample size assayed (100 grams
recommended).
. Use a check sample program for validation.
. Retain samples for a specified period of time.
26LABORATORY METHOD Currently preferred method is
that recommended by the Food and Drug
Administration's (FDA) Center for Veterinary
Medicine for isolating and identifying Salmonella
in rendered products. Published in the
Bacteriological Analytical of Official Analytical
Chemists (AOAC). It is often referred to as the
BAM method. The method can be obtained from FDA,

36DINASAL
Highly efficacious Salmonella inhibition
technology from
DIVERSIFIED NUTRI_AGRI TECHNOLOGIES Inc., DINATEC
37MODE OF ACTION
DINASAL
Hits the target everytime
Through its unique blend of highly effective
active ingredients and surfactants which empower
it to easily penetrate the bacterial cell wall
membrane into the cytoplasm. The ensuing
breakdown into anions and cations results in
rapid acidification of the cytoplasm interfering
with DNA, RNA, Protein Synthesis and various
other intercellular functions which will kill the
Salmonella organism.
38DINASAL
Will not interfere with the animals physiology or
immune system in any way
Will not interfere with vaccination programs

Head of Nutrition Department,
University of Florida. Phone (352) 392-1958
I have had extensive involvement in work with
probiotics and dealing with the immune system for
poultry. I have never heard that any formaldehyde
based product used in feed as approved by AFFCO
guidelines has had any effect of
immunosuppression or interference with
vaccination programs. Furthermore formaldehyde
solutions are used at much higher risk level with
1 day old chicks in the hatchery without
observable detrimental effects. At this time
there are no available studies known that confirm
or deny such a statement September 15, 2000
40Dr. Nelson Cox, Microbiologist, Fellow, American
Academy of Microbiology, USDA, Agricultural
Research Services, Poultry Microbiological
Research Unit, Russell Research Center, Atlanta,
GA
I am involved in extensive research in the field
of Salmonella control. I have not heard of any
immunosuppressive effects of formaldehyde based
feed additives for use in poultry as per AFFCO
guidelines for the control of Salmonella. I do
not know of, nor have I conducted any research
that would affirm or disclaim the above.

To my knowledge, I have never heard or observed
of an immunosuppressive effect of any feed
additive on chickens
Dated September 15, 2000
42Frank T. Jones, Ph.D.University of
ArkansasCenter of Excellence for Poultry Science
Dear Dr. Moreira .I was surprised to learn of
that formaldehyde based feed additives are
reported to have caused immune suppression and
vaccine interference. While I suppose it is not
impossible, I have heard no reports of this
effect in this country and I have seen no
scientific studies to suggest that such an effect
exists. Indeed, since formaldehyde has been
around for many years, it appears to me that such
an effect would have been observed and reported
at some point in time. Formaldehyde was used for
many years in hatcheries and still is used in
some hatcheries here. If such an effect exists
in feed, it would seem to me that we would have
seen a similar effect during the use of
formaldehyde in hatcheries.
43Frank T. Jones, Ph.D.University of
ArkansasCenter of Excellence for Poultry Science
It appears to me that immune competency in U. S.
birds would have improved as formaldehyde usage
became less. However, we have seen no such
effect. Furthermore, there are many, many
primary breeder flocks being fed formaldehyde
treated feed in this country. It seems to me
that since these primary breeder birds are
extremely valuable and are monitored for nearly
everything (including immunity), if such an
effect existed, we should have observed it here.Â
However, I have heard no field reports of this
effect in this country..
44BRIEF DISCUSSION CONCLUSION
The preceding are some of the top experts in the
field and Salmonella control in the United
States. It is evident that if such a condition as
immune suppression existed through the use of
formaldehyde based Salmonella control feed
additives they would know it. It is therefore a
safe assumption that since this problem has never
been reported in any scientific literature, nor
has there been any interest in conducting
research on the matter, the purported statement
has no factual basis.

50DINAMUNE
INMUNOESTIMULANT
51DINAMUNE
- Incorporates a 1-3 link 100 natural Beta Glucan
derivative as one of the most important active
ingredients. This Beta Glucan is derived from the
cell walls of the yeast known as S. cerevisiae.
- Use is indicated whenever there is a diminished
immune system. This condition may be aggravated
by the hosts succeptability to contagious viral
or bacterial deseases and by the presence of
certain types of immunosuppresant agents such as
many types of mycotoxins.
52DINAMUNEMODE OF ACTION
- Beta Glucans are able to activate macrophages or
macrophage like cells within the
reticuloendothelial system by stimulating a
specific receptor site on the macrophage.
Macrophages are able to trap and engulf foreign
substances. This event will initiate a cascade of
immunological events that will result in the
stimulation and strenghtening of the overall
immune system alerting it and mobilizing it in a
specific sequence. The result is the creation of
an immunological bank or reserve that will offer
continued protection to the host organism and
help it to ward off desease.
53DINAMUNEMODE OF ACTION
This illustration depicts the initial reaction in
cell mediated immunity. The macrophage has
processed an antigen and has inserted it into its
cell membrane. It then presents the antigen to
helper T cells in conjunction with the proper
histocompatability antigen which causes the
latter to become activated in the immunological
cascade cycle. The activated T helper cells will
then in turn activate cytotoxic T and B cells
54DINAMUNEASSIMILATION IN THE DIGESTIVE TRACT
- The digestive tract is lined with entherones and
entherocytes. These organisms produce a sticky
filamentous material that is called Glycocalix.
There are two types of receptors bound to this
Glycocalix. One such receptor is highly specific
and will adhere to long chain type molecules
engulfing them and pulling them towards the
interior area of the cellular walls in the
digestive system. This is one of the ways that
DINAMUNE works. The process wherein this is
accomplished is called Pinocytosis or Endocytosis.
55DINAMUNEBETA-GLUCAN
- Powerfull Immunological Stimulant.
- Has Anti-oxidant effects.
- Aids in the regeneration and repair of organic
tissue.
- Has antineoplastic effects.
- Has adjuvant characteristics with antibiotics,
vaccines,anti-parasites and mycotoxin adsorbants
and mold inhibitors.
56DINAMUNEBETA-GLUCAN
- Will not over stimulate the immune system nor
will it elicit an anti-immune response.
- Will not interfere with other medication being
concurrently administered.
57DINAMUNEASIMILATION IN THE DIGESTIVE TRACT
- Polysacharides are transported through the inner
lining of the lateral intestinal walls towards
the lymphatic system and from there into the
blood stream.

BIOAGLUTINATION
60MODE OF ACTION
I.M.M.
Depends on animal species, type of diet and stage
of lactation.
For Ruminants
Studies show increase in total number of
anaerobic microorganisms, including cellulolytic
(fiber digesting) and lactate-utilizing bacteria,
in the rumen.
Production of B-vitamins, proteins and other
nutrients used by beneficial intestinal microbes
for growth.
Utilization of oxygen in rumen improves growth of
strictly anaerobic bacteria.
Oxygen inhibits adhesion of cellulolytic bacteria
to fiber. Dinaferm improves rate of fiber
digestion by increasing cellulolytics thereby
stimulating feed intake and production.
Increase in lactate-utilizing bacteria and
subsequent decrease in lactate levels in the
rumen of animals fed Dinaferm stabilize rumen
pH, which leads to increased numbers of
cellulolytics. Important when feeding high
concentrate rations where rumen pH can drop to
acidosis levels.
61MODE OF ACTION
I.M.M.
For Ruminants
Increase in total rumen bacteria is associated
with
Increased ammonia uptake
Increased levels of microbial protein leaving the
rumen and subsequent increased supply of amino
acids to the small intestine.
Microbial protein supplements the duodenal
protein and boosts milk production in early
lactating cows.
Research indicates response is greater when ratio
of concentrate to forage is higher and fed during
late dry or early lactation phase.
62MODE OF ACTION
I.M.M.
For Poultry, swine and horses
Poultry swine and horses have shown positive
response. Improvements in productivity are
consistent.
Broiler chickens show a 7-8 improvement in
growth as substantiated by research in the
supplementation of S. cerevisiae based diets to
broilers.
Research also indicates Dinaferm's ability to
help bind 100 of the Aflatoxin content in feed
and more than 40 of T-2 as well as DAS.
