Description
Summary:Introduction The safety of poultry meat products and contamination with microorganisms is based on appropriate reduction of the presence of pathogens during poultry rearing and is closely related to the level of rearing hygiene, including the type of housing, stocking density, microclimate, sanitation and ventilation. Objective The aim of the study is to evaluate the prevalence of Campylobacter -positive samples in Iceland during 2016ā€“2018, and to compare the potential influence of individual parameters of welfare on the prevalence of Campylobacter spp. Material and methods Positivity of excrement and caecum samples for Campylobacter spp. was determined according to ISO 10272ā€“1: 2006 and 2017. Data of welfare indicators were collected during the rearing period and in the slaughterhouse. Results Considerable seasonality was observed in the prevalence of Campylobacter spp. The prevalence of campylobacteriosis on the investigated broiler farms was significantly higher (p Ė‚0.05) during the summer. Comparison of welfare parameters on Campylobacter -positive and Campylobacter -negative farms failed to indicate a significantly higher level of observed welfare indicators in birds from Campylobacter -positive farms (pĖƒ0.05). In comparing small, medium and big farms, a significantly higher occurrence was observed (p<0.05) of the FPD score over 40, stocking density, and the average slaughter weight, and percentage of mortality over 2% in small farms. Conclusions Intensive management and the environment affect the welfare of poultry and its resistance to infections ( Campylobacteriosis ) and thus increase the health risk. Checking the welfare parameters in a slaughter house provides delayed improvement of the environment on farms, but it can also lead to changes in the following production cycles (decreasing of stocking density).
