MEAT BORNE DISEASES TO HUMAN FROM RABBITS
RABBITS DISEASES TO HUMAN VIA MEAT
DISEASE CAUSED BY BACTERIA
- Pasteurellosis (Snuffles, Pneumonia)
DISEASES CAUSED BY PARASITES
Disease caused By Helminths
- Tapeworm larvae in rabbits
Disease caused By
Protozoa
- Coccidiosis
MEAT BORNE – BLUETONGUE, CATARRHAL FEVER IN SHEEP
MEAT
BORNE – BLUETONGUE IN
SHEEP
Bluetongue is
an infectious non-contagious arthropod borne viral disease of domestic and wild
animals characterized by high fever, catarrhal inflammation of buccal mucous
membrane (stomatitis) and nasal mucous membrane (catarrhal rhinitis),
emaciation. Inflammation of tongue, intestine, sensitive laminae seen.
Transmission:
Biting insects, especially gnats and mosquitoes, ectoparasites. Semen of infected bulls, placental routes and mechanical transfer – infected blood by needles.
Ante-Mortem
findings (Done before death in a slaughter house):
In Sheep:
Incubation period 6-8 days.
High rise of temperature and fever
Difficult breathing
Excessive salivation
Loss of appetite, weakness and emaciation
Relucatance to move
Swellings of gum, muzzle, lip and tongue
Mucopurulent to bloody nasal discharge
Cyanosis of the tongue and mucous membranes
(bluetongue) with erosion
Lameness
Inflammation of the coronary band and painful
hoof
Abortion and deformed lambs
Death (Respiratory failure)
Post-Mortem
findings (Done After death in a slaughter house):
Mouth – there is hyperaemia
Tongue – becomes blue and gangerenous
Leg – coronary band shows congestion and hemorrhage
Skeletal and cardiac muscle – necrosis
Lungs – congestion
Placenta – hemorrhage
Spleen – enlarged
Subcutaneous tissue – edema and hemorrhage
Judgement:
The whole carcass
and viscera are condemned (in many countries)
In acute stage if
become normal (on recovery stage) then can be used for consume

MEAT BORNE - AVIAN INFLUENZA (AI), FOWL PLAGUE, HPAI
AVIAN INFLUENZA (AI) - Poultry
- AI is a viral disease of avian species. The disease can be range from asymptomatic and mild to fatal. Avian influenza occurs infrequently in humans. AI is highly contagious viral diseases of poultry characterized by high mortality and morbidity, pericarditis, air sacculitis, pneumonia, caseous exudate in upper respiratory tract and cyanosis of comb.
Transmission:
- Direct and indirect transmission from infected birds, by wild birds, contaminated feed.
Ante-Mortem findings (Done before death in a slaughter house):
- Incubation period varies for few hours to about seven days.
- Marked depression
- loss of body weight
- Watery diarrhoea
- Coughing, sneezing, rales, excessive lacrimation
- Drop in eggs production
- Conjunctiva is swollen and congested
- Swollen combs with cyanosis color appear
- Ruffled feathers
- Blood in the cloaca
- Some birds may recover rare
Post-Mortem findings (Done After death in a slaughter house):
Highly pathogenic infection:
- Dehydration
- Birds die with peracute form of AI
- Fibrinous exudate found in airsacs, oviduct, peritoneum, pericardial sacs
Mild infection:
- Inflammation of conjunctiva, trachea, airssacs
- Congestion of musculature
- Petachial hemorrhage in abdominal fat, mucosal surfaces, heart, gizzads, proventriculus, intestine
- Edema of the head with congestion, hemorrhage, cyanosis, wattles and sinuses
- Ovarian regress seen in laying birds
- Feet is edematous with hemorrhage
Judgement:
- The whole carcass and viscera are condemned
- Stumps done (any birds found to be positive case) of the flock and that area should be careful for the visitors

MEAT BORNE - PNEUMONIA (PIGS/SWINE)
PNEUMONIA
Pneumonia is an inflammation of the lungs caused by bacteria, viruses, fungi, parasites or physical/ chemical agents. It is with inflammation of the bronchi, bronchioli and the pleura, exactly the term is Bronchopneumonia. In pigs caused by Mycoplasma hypneumoniate and haemophilus pleuropneumoniae.Transmission:
Ante-Mortem findings (Done before death in a slaughter house):
- From mother (sow) to the suckling pigs.
- Adult via contact or air.
Enzootic pneumonia:
- No fever
- Acute respiratory distress
- dry cough present
Chronic pneumonia:
- Dry hacking cough
- Retard growth
Pleuropneumonia:
- Fever upto 41ÂșC
- Respiratory distress
- Bluish mucous membranes of the eye and mouth
- Bloody frothy discharge from nostrils

Post-Mortem findings (Done After death in a slaughter house):
Enzootic pneumonia:
- Plum colored, greyish consolidation cardiac and lungs lobes
- Enlarged bronchial lymph nodes
- Purulent pneumonia with abscessation
Chronic pneumonia:

MEAT BORNE - FOOT AND MOUTH DISEASE
FOOT AND MOUTH DISEASE (FMD)
FMD
is an acute viral and highly contagious diseases
of cloven-footed animal characterized
by high fever 104-106°F. High
fever anorexia depression, fallen milk, milk yield formation of vesicular
eruption in mouth, feet and teats.
Transmission:
- Direct contact or indirect contact with infected animals and contaminated fomites; routes of spread include inhalation of aerosolized virus, ingestion of contaminated feed.

GARLIC EFFECT AND PROPERTIES
GARLIC
Antimicrobial
properties in meat:
Antimicrobial
effects of chopped garlic in ground beef and raw meatball decreased the
microbial count and growth.
Digestion:
Garlic assists in
normal functioning of the intestines for good digestion.
Eye
care:
Garlic
contains nutrients like Selenium, Quercetin and Vitamin C which helps treat eye
infections and swellings.
Intestinal
problems:
It clears most of
the intestinal problems like dysentery, diarrhea and colitis.
Sexual
problems:
To enhance the
libido ability of both men & women. People who overindulge in sexual
activities should take garlic in diet or supplement form to protect their
selves from sheer nervous fatigue.
Asthma:
Boiled cloves of
garlic do wonders for asthma treatment.
Highly
Nutritious:
Garlic
is low in calories and very rich in Vitamin C, Vitamin B6 and Manganese. It
also contains trace amounts of various other nutrients.
Cold:
Garlic
function is to boost the immune system. It helps to prevent and reduce the
severity of common illnesses like common cold and flu.
Reduce
Blood Pressure:
High
doses of garlic appear to improve blood pressure of those with known high blood
pressure (hypertension). In supplementation can be effective as regular
medications.
High
cholesterol levels:
Of
the two kinds of cholesterol –LDL and HDL, the former is bad for human health.
Garlic, rich in allicin compound effectively prevents LDL cholesterol from
oxidization. All those who have high cholesterol level must include garlic in
their daily diet.
Garlic
Contains a Compound Called Allicin:
It
is higher in sulfur compound called Allicin, which is believed to bring most of
the health benefits.

HACCP NEW APPROACH FOR FOOD SAFETY
HACCP
·
HACCP stands for Hazard Analysis and
Critical Control Point
·
HACCP system is -
·
A systematic approach to the
identification, assessment and control of hazard
·
A management tool for food safety
assurance focuses on prevention
·
An applied at any stage in food chain
production, from farm to consumer (Public)
HACCP
is a system which identifies specific hazards (i.e. biological, physical and
chemical property that cause an adverse health affect) and specifies measures
for their control
u Take
HACCP Certified food product e.g. Meat product and more
u To
Control the Major zoonotic diseases (given in other blog link below)-
