This document discusses guidelines for meat inspection and summarizes several important parasitic diseases. It provides inspection criteria for various organs and carcasses of cattle, sheep, and pigs. It describes parasites such as Cysticercus bovis, Echinococcus granulosus, Taenia hydatigena, Taenia multiceps, Fasciola hepatica, Trichinella spiralis, and Taenia solium. Judgment guidelines are given for different levels of parasite infections, ranging from removal of affected tissues to total condemnation of carcasses.

Taxonomy
Kingdome : Animalia
Phylum : Platyhelminths
Class : Trematoda
Order : Opisthorchiida
Family : Opisthorchiidae
Genus : Clonorchis
Species : C. sinensis
Introduction
•
Clonorchis is also known as the Chinese or oriental liver fluke.
Clonorchis is a liver fluke parasite (trematode or worm) that can
infect the liver, gallbladder, and bile duct.
food born parasite
Host
Definitive Hosts
First intermediate host must always be a snail, mainly
Parafossarulus manchouricus
Life cycle
•
Clonorchis sinensis eggs are discharged in the biliary ducts and in
the stool in an embryonated state
Eggs are ingested by a suitable snail (P. manchouricus)
intermediate host
Eggs release miracidia
which go through several developmental stages (sporocysts, rediae, and
cercariae).
The cercariae are released from the snail and, after a short period
of free-swimming time in water, they come in contact and
penetrate the flesh of freshwater fish, where they encyst as
metacercariae
Infection of humans occurs by ingestion of under cooked, salted,
pickled, or smoked freshwater fish
After ingestion, the metacercariae excyst in the duodenum
and ascend the biliary tract through the ampulla of Vater
Maturation takes approximately one month. The adult flukes
(measuring 10 to 25 mm by 3 to 5 mm) reside in small and
medium sized biliary ducts.
they lay eggs in intestine
the embryonated eggs release in stool.
The eggs are embryonated and contain the larvae called miracidia.
The sporocyst resembles a hollow and simple sac.
Oftentimes, the developing rediae are visible inside the sac.
Redia - At this larval stage, it retains a very simple worm structure.
In some ways, it still resembles a sac.
Pathogenesis
Liver flukes infect the liver, gallbladder, and bile duct in humans.
inflammation in biliary epithelium
Laboratory Findings
Blood routine test: eosinophilia, anemia in severe infection

Tropical theileriosis or Mediterranean coast fever Ranjini Manuel
heileriases are a group of tickborne diseases caused by Theileria spp. A large number of Theileria spp are found in domestic and wild animals in tick-infested areas of the Old World. The most important species affecting cattle are T parva and T annulata, which cause widespread death in tropical and subtropical areas of the Old World. T lestoquardi, T luwenshuni, and T uilenbergi are important causes of mortality in sheep.

5. Stamping of carcassStamping of carcass
• stamping is chiefly a mean for identification .
Aim of stamping
• to indicate that the carcass is wholesome
• to differentiate between animal species
• to differentiate between aged and young animals of
the same species
6. Stamping of carcassStamping of carcass
The impression of the stamps refer to:
• the name of province
• the name of abattoir
• the day of slaughter
• a secret mark
• the kind of meat age and species
• no of slaughter hall
• the ink of staining must be harmless, adhere easily
,stable ,dry Quikley penetrate into the superficial layers of
meat impressions should not be disappeared by washing
pickling or smoking

9. Parasitic Diseases important in MeatParasitic Diseases important in Meat
InspectionInspection
Taenia saginata
C. bovis(Beef Measles)
• Predilection sites are tongue, heart muscle,
massater, diaphragm .Occasionally in liver and
lungs.
Final host is man, intermediate host is bovine(Cattle).Other
wild ruminants are infected.
13. Judgment at meat inspectionJudgment at meat inspection
• Condemn the whole carcass if;
– the infection is excessive i.e. if any muscle you
incise, you find 1 or more cysts or any organ you
incise you find 1 or more cysts.
– The total number of cysts in any muscle or
surrounding tissue or organ exceed 10 just on a
single incision
– 10 or more cyst in a dressed carcass
14. Judgment at meat inspectionJudgment at meat inspection
• When the carcass regarded less number of
cysts
• Conditionally approve if the carcass
– Has 1-9 cysts
– Any part of the carcass has 1 or 2 cysts
15. Echinococcus granulosusEchinococcus granulosus
Hydatid diseaseHydatid disease
• Final host is dog and other carnivorous.
• Intermediate hosts are cattle, ruminants, pigs,
• Man is an accidental intermediate host
• The cystic form is hydatid cyst
18. Judgment at PMJudgment at PM
• The shape of cysts depend on shape and size of
organ where the cyst is located.
• It can be spherical and can be very large
• Leading to pressure necrosis.
• Carcass showing emaciation, edema is
condemned and destroyed.
• Affected viscera condemned and destroyed.
19. Taenia HydatigenaTaenia Hydatigena
• Its among the largest tape worms of dogs. The
cystic form is cysticercus tennuicolis found
intermediate hosts which are small
ruminants(goats and sheep) and pigs.
• It is one of the largest cysts up to 7.5 cm with
a long thin neck.
• Predilection sites include the omentum,
mesenteries & liver.
21. Taenia HydatigenaTaenia Hydatigena
• Judgment
– If infestation is not heavy remove cyst and pass
carcass
– In case of excessive infestation, condemn the
affected organs.
– Man is an accidental host
22. Taenia multicepsTaenia multiceps
• It confined to brain tissue of ruminants
• Can be size of a pea or an egg.
• Can be arrested in liver and die, otherwise reach
brain in 8-14 days leading to CNS signs
• Final host carnivores
• Intermediate hosts- ruminants
• Judgment
– In early cases when there is no emaciation,
condemn the head
– If there is emaciation, condemn the whole carcass
23. FascioliasisFascioliasis
• Caused by Fasciola hepatica, Fasciola
gigantica
• At post mortem, acute lead parachymatous
hepatitis, hemorrhages..
• Bile ducts are thickened, dilated, Bile ducts filled
with yellowish brown bile containing flukes
• Excessive calcification and fibrosis of ducts leads to
liver cirrhosis.
• Migrating flukes may reach other organs like lungs
28. Taenia Solium(PorkTaenia Solium(Pork tape wormtape worm((
Final host is man, intermediate host is pig. Larvae
is picked by the pig
•Active muscles include heart muscle, diaphragm,
massatter muscles, tongue, abdominal muscles,
neck etc.
•This cystic form is know as cysticercus cellulosae.
•The condition is know as cyticercosis. Also
known as pork measles
30. Cyst in the Peritoneal cavityCyst in the Peritoneal cavity

the heart musclesthe heart muscles..
32. T. SoliumT. Solium
Judgment at Meat inspectionJudgment at Meat inspection
• If the total number of cysts is more than 6,
condemn the whole carcass.
• Any organ or head or any part of the pig with 1 or
more cyst should be condemned.
