As a result of continuous increase in poultry production and poultry breeding selection numerous forms of diseases appeared including the green muscle disease. The goal of the study was to determine the influence of the green muscle disease on quality of meat subjected to thermal processing. The material for the study consisted of 55 samples of the major pectoral muscles originating from female post-production turkeys and turkey broilers. The samples were subjected to organoleptic evaluation and tests aimed at determining the meat tenderness. On the basis of the results obtained it is concluded that the meat originating from turkeys suffering from the green muscle disease, subjected to thermal processing, shows significant differences in cross-section color, juiciness and taste.

Breeding selection of slaughter poultry aimed at assuring fast body weight gains of birds has resulted in the occurrence of various forms of chronic diseases, including deep pectoral myopathy, also known as green muscle disease. The objective of the study was to determine the hygienic and technological value of meat of turkeys originating from flocks with diagnosed green muscle disease. The experimental material comprised 376 samples of the major and minor pectoral muscle from post-production turkey hens. The samples were subjected to microbiological analyses as well as determinations of pH, water binding capacity, color and chemical composition (fat, protein, water). The results obtained enabled concluding that, in terms of microbiological assessment, the meat originating from turkeys affected by the green muscle disease may be acknowledged as suitable for consumption. In turn, due to negligibly diminished technological value, resulting from deviations in pH value, water binding capacity, color and chemical composition, the authors postulate considering the advisability of stipulating separate qualitative standards for meat originating from post-production turkey hens.

The aim of the study was to determine the incidence of Campylobacter spp. in broiler chickens during the breeding cycle of 16 flocks from three farms (4 sheds) located in north-eastern Poland. Sampling, sample preparation, and microbiological tests for Campylobacter spp. were performed according to the Polish Standard PN-EN ISO 10 272 – 1: 2007. During the breeding cycle of each flock, 60 cloacal swabs and 63 samples from the internal environment of the chicken house (walls, farm equipment, shoes, clothing and hands of the workers, as well as feed and water) were collected. Samples were taken on day „0”, i.e. prior to the insertion of chicks, and at the end of the 3rd and 5th weeks of chickens’ life. The study was conducted over 9 consecutive seasons. A total of 960 cloacal swabs and 1008 samples from the internal environment of poultry houses were tested. None of the internal environment samples taken on day „0” was positive for Campylobacter spp., nor were the feed and water samples or those collected from the hands of the workers, regardless of the breeding cycle phase. However, in the 3rd and 5th weeks of the rearing period, Campylobacter spp. were isolated from 24.9% of cloacal swabs and from 19.8% of litter samples in 6 out of the 16 surveyed flocks. The frequency of isolation of Campylobacter spp. from those samples depended significantly (p ≤ 0.05) on the season and was the highest in the summer. Among the other samples from the internal environment, 0.4% were positive and came from 5 flocks. The presence of Campylobacter spp. was confirmed on all surveyed farms with frequency depending on the season, sample type, phase of the breeding cycle, and farm. This indicates the need for constant implementation of the highest hygiene regimes and rules of biosecurity throughout the production cycle of chicken broilers, regardless of the season.

A total of 71 broilers, 174 pigs, and 277 cattle were examined in a slaughterhouse. Samples of the contents of the small intestines and swabs from carcass surfaces were collected. Campylobacter spp. were isolated from the intestinal contents of 100% of poultry, 51.1% of swine, and 36.4% of cattle. The prevalence of Campylobacter spp. was confirmed in 91.5%, 29.8%, and 10.5% of swab samples, respectively. In the case of humans with gastrointestinal symptoms, Campylobacter spp. were isolated from 46 out of 1347 (3.4%) fecal samples. The majority of isolates from humans, poultry, and cattle were identified as C. jejuni, whereas swine isolates were mainly positive for C. coli. Antimicrobial susceptibility tests were performed by the disc diffusion method. Antibiotic profiling showed that Campylobacter strains isolated from humans and animals were most frequently resistant to quinolones and fluoroquinolones. Ciprofloxacin susceptibility was found in 35.5% of poultry isolates, 38.3% of swine isolates, 46.1% of cattle isolates, and 41.3% of human isolates. The rates of susceptibility to nalidixic acid in these isolates amounted respectively to 25.9%, 48.2%, 40.0%, and 36.9%. These findings indicate that the above-mentioned groups of antibiotics should not be recommended against Campylobacter infection in Poland. In contrast, susceptibility to erythromycin was observed in 100% of cattle isolates and 91.3% of human isolates. Gentamicin was effective in 100% of swine and poultry isolates, 94.6% of cattle isolates, and 89.1%, of human isolates. These results prove the usefulness of erythromycin and gentamicin in the treatment of campylobacteriosis.
