7.7.1 Sick swine shall be handled according to GB 16548.

7.7.2 Flocks shall be quarantined according to regulations. Those confirmed to be disease-free can be slaughtered normally. Those showing clinical symptoms shall be treated as sick swine.

7.3 Swine found to have other diseases or physical injuries other than those listed in 7.5,

7.6 and 7.7 of this specification during pre-slaughter quarantine shall be urgently slaughtered in the emergency slaughter room and handled in accordance with the provisions of GB 16548.

7.9 For sick swine detected during pre-slaughter quarantine, the animal epidemic

prevention and control supervision agency at the place of origin shall be notified based on the ear tag code and quarantine certificate to trace the source of the disease.

changes, and gelatinous exudate. Pay attention to the presence of swine fever, swine erysipelas, septicemic anthrax, and paratyphoid.

8.3.4 Spleen inspection. Visually inspect the shape, size, and color. Check for swelling, congestion, and infarction. Palpate the capsule and parenchymal elasticity. If necessary, dissect the spleen and marrow. Pay attention to the presence of swine fever, swine erysipelas, and septicemic anthrax.

8.3.5 Lung inspection. Visually inspect the shape, size, and color. Touch and check for elasticity. Dissect the bronchial lymph nodes. If necessary, dissect the lungs. Check for exudate in the bronchi, and for collapse, emphysema, edema, congestion, abscesses, calcifications, parasites, etc. in the lung parenchyma.

8.3.6 Heart inspection. Visually inspect the pericardium and epicardium. Palpate the

myocardial elasticity. Open the ventricle longitudinally at the atrioventricular division at the posterior edge of the heart parallel to the left longitudinal groove. Observe the mitral valve, myocardium, endocardium and blood coagulation status. Check for degeneration, exudation, hemorrhage, necrosis, cauliflower-like growths, villous heart, tiger-striped heart, cysticercosis, etc.

8.3.7 Liver inspection. Visually inspect the shape, size, and color. Touch the capsule

and parenchyma for elasticity. Dissect the hepatic portal lymph nodes. If necessary, dissect the liver parenchyma and gallbladder. Check for congestion, edema, degeneration, jaundice, necrosis, sclerosis, tumors, nodules, parasites, and other lesions.

8.3.8 Gastrointestinal inspection. Observe the gastrointestinal serosa for abnormalities.

Dissect the gastrointestinal tract if necessary. Inspect the mucosa. Observe the mucosa for congestion, edema, bleeding, necrosis, ulcers, ileocecal valve button swelling, nodules, parasites and other lesions.

8.3.9 Kidney inspection (conducted together with carcass inspection). Remove the renal

capsule. Visually inspect the shape, size, color and surface condition. Touch the texture.

If necessary, longitudinally dissect the renal parenchyma. Check for congestion, bleeding, swelling and other lesions, as well as for exudates, stones, etc. in the renal pelvis.

8.3.10 If necessary, the bladder shall be dissected for abnormalities. The mucosa shall be observed for congestion and bleeding.

8.4 Carcass quarantine

8.4.1 The focus of the inspection is to check for diseases such as swine fever, swine plague, anthrax, swine erysipelas, streptococcus, pleuropneumonia, tuberculosis, trichinosis, cysticercosis, sarcoma, and leptospira.

8.4.2 Appearance inspection. Visually inspect the skin before opening the body.

Visually inspect the subcutaneous tissue, fat, muscle, and thorax and abdominal serosa after opening the body. Check for congestion, bleeding, rash, jaundice, abscesses, and other abnormalities.

8.4.3 Lymph node inspection. Open and inspect the anterior shoulder lymph nodes, superficial inguinal lymph nodes, internal iliac lymph nodes, and anterior thigh lymph nodes. If necessary, dissect and examine the extrailiac lymph nodes and deep inguinal (or subiliac) lymph nodes. Check for congestion, edema, hemorrhage, necrosis, hyperplasia and other lesions. Pay attention to swine fever marble lesions.

8.4.4 Muscle inspection

8.4.4.1 Dissect the deep psoas and vastus medialis muscles on both sides. If necessary, check the lateral scapularis muscle. Check for cystocele and white muscle (PSE meat).

Cut the deep psoas muscles on both sides along the direction of the muscle fibers. The knife mark is 20 cm long and about 3 cm deep. Cut the vastus medialis muscle longitudinally, with a knife mark of 15 cm long and 8 cm deep. Cut the lateral scapularis muscle longitudinally along the inner side of the scapula. The knife mark is about 15 cm long and 8 cm deep.

8.4.4.2 Check the diaphragm. Mainly check for Trichinella spiralis, Sarcosporida, and

Cysticercus. Trichinella spiralis and Sarcosporida are checked by naked eye inspection and laboratory testing. Take a piece of meat sample of no less than 30 g from each diaphragm leg of each swine and assign the same number as the carcass. Tear off the fascia. Observe with the naked eye for the presence of needle-tip-sized white dot- shaped Trichinella body or cysts, and willow-leaf-shaped Sarcosporida.

Laboratory test for Trichinella spiralis: Cut 24 meat pieces from the above samples (12 pieces per piece of meat sample) and make muscle slices. Place them under a low-power microscope or a Trichinella spiralis projector for inspection. If conditions permit, the sample digestion method can be used for inspection.

8.5 Remove the immunization ear tag. If the quarantine fails, remove the ear tag immediately. Trace the source of the epidemic based on the ear tag code.

8.6 Re-inspection. After the above quarantine process is completed, the quarantine officer will re-inspect the quarantine situation. Comprehensively determine the quarantine results. Supervise and inspect the removal of the thyroid gland, adrenal glands and abnormal lymph nodes. Fill in the post-slaughter quarantine record.
