Inactivation of the bovine spongiform encephalopathy agent by rendering procedures.

Bovine brain infected with the bovine spongiform encephalopathy (BSE) agent was used to spike material processed in pilot scale facsimiles of 12 rendering processes which are used within the European Union, and three which are not. The raw materials for experimental rendering represented those used in practice, and consisted of appropriate proportions of BSE-infected brain tissue, bovine or porcine intestine, and bovine bone. Meat and bone meal, and tallow were produced from the rendered tissues. Suspensions of all the meat and bone meal samples were assayed in inbred mice for BSE infectivity, and two of the tallow fractions were tested similarly. Four of the 15 processes produced meat and bone meal with detectable BSE infectivity. Neither of the tallow samples had detectable infectivity.

California National Animal Health Monitoring System for meat turkey flocks-1988-89 pilot study: management practices, flock health, and production.

A pilot project for a meat turkey National Animal Health Monitoring System was undertaken in California in 1988-89 to explore data gathering techniques and to estimate the frequency, magnitude, and variability of management, flock health (including administration of pharmaceuticals for prevention and treatment of disease), and production variables in order to facilitate planning for future food animal monitoring systems. Enteritis, which occurred in over one-third of the flocks, and colibacillosis, which occurred in nearly one-quarter of flocks, were the most common diseases reported. Mycoplasma synoviae was reported in two flocks and Mycoplasma gallisepticum and Mycoplasma meleagridis each were reported in one flock. Total mortality rate in the sample flocks was 9.0% (95% confidence interval [CI] 8.2%-9.8%). The tom-specific mortality rate was 10.9% (95% CI 9.8%-12.1%) and the hen-specific mortality rate was 6.6% (95% CI 5.7%-7.4%).

Enhancing health care to underserved populations: a model for the occupational nurse practitioner.

1. A nurse practitioner managed health unit for a meat packing/rendering company demonstrates a practice model for providing quality, cost effective health care to a specific population. 2. To gain management support for wellness and health promotion programs, unit cost effectiveness was demonstrated. 3. This model demonstrates success in the use of the nurse practitioner to provide care to a population that traditionally does not seek preventive or early health care.

Description of cellulitis lesions and associations between cellulitis and other categories of condemnation.

A total of 110 broiler flocks processed in a single processing plant in southern Ontario were studied for purposes of describing the cellulitis lesions and investigating possible associations between cellulitis and other categories of condemnation at the processing plant. Two hundred and ninety-five carcasses condemned for cellulitis were examined. They came from 65 of the 110 flocks. The lesions tended to be unilateral with most carcasses (87%) having one lesion. The majority of the lesions (92%) were located on the abdomen. Almost 65% of the lesions were large (> or = 8.1 cm2), and 27% were medium (2.1-8.0 cm2). On the basis of gross appearance, 69% of the lesions were classified as severe, 26% moderate, and 5% mild. Of 149 lesions examined histologically, 74% were classified as chronic, 21% ongoing, and 5% mild-acute. Condemnation data from the 110 broiler flocks were analyzed using Poisson regression. Simple relationships were examined between a count outcome (number of cellulitis-condemned carcasses per flock) and other categories of condemnation and average bird weight. Cellulitis was significantly associated with average bird weight (P = 0.0018), Escherichia coli-related conditions (SEROSITIS; P < or = 0.0001), ascites (P = 0.0004), cyanosis (P < or = 0.0001), valgus varus deformity (P < or = 0.0001), REJECT (combined carcass condemnations for bruising, mutilation, and contamination; P = 0.0003), and the interaction terms "average bird weight and ascites" (AVWT*ASCIT; P < or = 0.0001) and "average bird weight and cyanosis" (AVWT*CYAN; P < or = 0.0001). Average bird weight, SEROSITIS, ascites, cyanosis, valgus varus deformity, and AVWT*ASCIT were the only significant factors after adjusting for clustering. No association was observed between cellulitis and emaciation and dead on arrival. Variables significantly associated with cellulitis in the multivariate analysis could be considered as potential predictors. These predictors may share common risk factors predisposing broiler chickens to cellulitis.

[Determination of tetracycline in bones, mechanically separated bones and meat using HPLC and microbiological plating methods].

HPLC method with solid phase extraction, and microbiological agar diffusion tests for determination of oxytetracycline (OTC), tetracycline (TC) and chlortetracycline (CTC) in bones, mechanically separated beef and bones were developed. Both mechanically separated bones and bovine flat bones showed the highest yield of tetracyclines by HPLC method. Among tetracyclines, the highest yield was determined in chlortetracycline. The strains of Bacillus subtilis (PH 6.0) and B. stearothermophilus showed the highest sensitivity to the presence of tetracyclines.

Hand and lower arm injuries among New Zealand meat workers and use of protective clothing.

AIM: To characterise work related hand and lower arm injuries among New Zealand meat processors and to identify practices used for protecting the hands of this group of workers. METHODS: These involved identifying and describing, from Department of Health national data, hand and lower arm injuries sustained by meat workers in New Zealand which resulted in hospitalisation during the period 1979-88, examining injury case records from selected meat processing plants for the period 1987-93 and identifying protective clothing practices in the meat processing industry. RESULTS: A significant increase in the hospitalisation rate for the period 1979-88 was identified (3.3 per 1000 to 5.3 per 1000; chi(2) = 33.14, df = 1, p < 0.001) with cutting and piercing being the most common injury event. Reported use of protective gloves and covers for the lower arm by meat workers was high (93% and 66% respectively) and also probably increased. CONCLUSION: Why injury rates rose during a period in which use of protective gloves reportedly increased is unclear. Possible explanations are discussed.

[Evaluation of the quality of poultry meat and its processing for vacuum packaging].

The aim of study was to evaluate the quality of poultry meat, roasted and smoked chicken and poultry pie packing under low and high vacuum. All investigated products were stored at +4 degrees C and evaluated by microbiological analysis. It was showed that packing under low and high vacuum inhibited development of aerobic microorganisms, proteolytic bacteria, yeasts and moulds. Vacuum-packaged storage of poultry meat and its products stimulated activity of anaerobic, nonsporeforming bacteria. The fast spoilage of fresh poultry meat was observed both under vacuum and conventional storage. The microbiology quality of poultry products depended on technology of production and microbiological quality of raw material.

Sero-epidemiological studies on Toxoplasma gondii infection in man and animals in Bangladesh.

Sera from randomly selected 49 professional blood donors, 617 pregnant women, 14 butchers, 528 slaughtered goats and 24 domestic cats in the district of Mymensingh were tested for the presence of T. gondii antibodies using a Latex agglutination test (LAT). Overall 12.4% blood donors, 11.18% pregnant women, 50.00% butchers, 12.88% slaughtered goats and 33.33% cats had diagnostically significant antibody titers (> or = 1:64) to T. gondii. Epidemiological studies on T. gondii infection with LAT were conducted in 25 family members with sero-positive cats and 9 family members with 2 sero-positive women without cats in the family. Significantly (p < 0.01) higher sero-positivity rate was recorded in the family members (24.00%) with positive cats in comparison to family members (11.11%) without cats. The epidemiologic study indicates that infected cats and goat meat might be significant sources of T. gondii infection for humans in Bangladesh.

Respiratory tract illness in meat wrappers.

A questionnaire survey was done in 152 Houston supermarkets to assess the prevalence of respiratory tract symptoms in meat wrappers exposed to the thermal decomposition fumes of polyvinyl chloride (PVC) film wrap and in two supermarket control groups (checkers and meat cutters). Meat wrappers had increased respiratory tract symptoms; 12% of meat wrappers who smoked (vs 6% and 2% of controls) and 5% of meat wrappers who did not smoke (vs 0% and 0% of controls) had multiple respiratory tract symptoms. It is probable that a large number of meat wrappers have mild symptoms with some progressing to more severe respiratory impairment or clinical asthma.

Food poisoning caused by parahaemolytic and NAG vibrios after eating meat products.

At total of 15 subjects taken ill with food poisoining caused by parahaemolytic and NAG vibrios after eating boiled pork sausage and boiled veal stomach were examined. The meat products were secondarily contamined in the sausage factory due to the use od non-disinfected lake water which was found to be a natural medium of the vibrios. When the use of this water was prohibited, the contamination of the factory and the meat products disappeared and no further cases of food poisoning due to meat products were notified. The disease has a toxic character, runs a bening course and end after 2--3 days by restoration to full health.
