Incidence of neurofibroma in cattle in abattoirs in New South Wales.

The incidence of neurofibroma in slaughtered cattle in New South Wales during a four-year period is reported. Most of the cases were in adult Hereford females over 5 years old. In 24 of the herds to which neurofibroma cases were traced there was evidence that the disease had previously occurred in the herd. However, the data does not indicate close familial relationship among cases of neurofibroma.

Plasma constituents of "downer" sheep slaughtered at an abattoir.

Haematocrit values and plasma glucose, calcium and magnesium concentrations were determined in blood samples collected at slaughter from 105 sheep that were prostrate, comatose, and unable to stand (downer sheep) on arrival at a Queensland meatworks. These values were compared to published normal concentration ranges of these plasma constituents and to values from blood samples taken from 107 apparently normal animals at slaughter. Eleven per cent of the "downer" sheep were considered hypocalcaemic, 13% showed varying degrees of hypoglycaemia and 22% were considered hyperglycaemic.

The contamination with Salmonella of bovine livers in an abattoir.

Fifty livers from normal slaughter cattle were examined for surface contamination by Salmonella immediately after evisceration and again after inspection. Salmonella were isolated from 32% at evisceration and from 82% after inspection. Numbers of Salmonella present were low at evisceration, and rose after inspection. In only one liver was the parenchyma infected. The sources of the Salmonella were probably the contents of the gastrointestinal tract and the mesenteric lymph nodes, both of which may show high prevalence of infection in cattle which have been held before slaughter. It was concluded that edible offal should be separated from the viscera at evisceration and inspected by personnel who are not involved with the alimentary tract.

The detection of arthritis in pigs in an abattoir and its public health significance.

The results of a study of the prevalence in each joint of arthritis in pigs as detected by meat inspectors is presented. A prevalence of arthritis in 1.07% of carcases was obtained, of which 0.28% were condemned totally and 0.79% condemned partially. With partial condemnations there was a bias to the left side in the hindquarters, and a significant bias to the hindquarter as compared with the forequarter. A consequence was that undetected arthritis lesions, especially in the forequarter and probably containing viable Erysipelothrix rhusiopathiae, are finding their way to the consumer.

An abattoir survey of diseases of feral goats.

Caseous lymphadenitis was the most frequently encountered pathological condition in 3,720 feral goats examined during routine meat inspection procedures. Among 9 separate consignments of animals, the prevalence of infection averaged 7.4% (range 0.3% to 18.8%). The majority of lesions were seen in lymph nodes draining superficial body areas although many also occurred in internal nodes and organs. Corynebacterium ovis was isolated from 25 of 32 lesions submitted for bacteriological examination. Other conditions regularly encountered included pneumonia, cysticercosis, sarcosporidiosis and lice infestation, while myonecrosis, pleurisy, pericarditis, nephritis, hepatitis, cirrhosis and mite infestation were only occasionally found. A total of 171 serum samples were collected and tested against 17 antigens. Samples from 57.9% and 51.5% of goats showed positive serological reactions to the antigens for sarcosporidiosis and Q fever respectively.

Monitoring and surveillance in abattoirs of residues of antibacterial substances--a description of programs in Australia and the USA.

Australia and the USA are major international meat exporting countries. Both countries conduct programs to monitor and survey for antibacterial residues. Australian programs use a urine screening test, whereas the US programs use tissue fluids as the test medium. The development of surveillance programs to provide rapid feedback to producers is a feature of the Australian programs. The programs in each country compare favourably with regard to numbers of animals tested, results and action taken to prevent residues. The results of the Australian programs justify the promotion of a 'clean food' image for Australian meat products with respect to antibacterial drugs.

The prevalence of latent Equid herpesviruses in the tissues of 40 abattoir horses.

Equid herpesviruses 1 or 4 (EHV-1 or -4) were isolated by cocultivation from 60% of 40 horses examined at slaughter. The lymph nodes draining the respiratory tract were the most common source of virus. EHV-1 or EHV-4 was never isolated from the trigeminal ganglia (SLG). The polymerase chain reaction (PCR) detected virus in 87.5% of bronchial lymph nodes and a similar level in the trigeminal ganglia that were examined. By both assays approximately one third of the positive animals harboured both viruses. Equid herpesvirus 2 (EHV-2) was isolated from all but one of the horses and from > 75% of the lymph nodes draining the respiratory tract; alpha viruses were isolated only in the presence of EHV-2. The results indicate that latent EHV-1 and EHV-4 are widespread in the equine population and that the primary site of latency is the lymph nodes of the respiratory tract.

Spore survival during batch dry rendering of abattoir waste.

Normal batch dry rendering practice does not ensure sterile products, because bacterial spores are protected against thermal denaturation by the high fat-low water content environment which results from drying the materials at temperatures below those required for sterilization.
