Abstract
ABSTRACT We aimed to study the potential use of carcass condemnation data of broiler chicken slaughterhouses in Brazil as indicators in an animal welfare monitoring program, and to identify points to be addressed to increase data reliability. Data from 2010 to 2015 in the states of Parana (PR), Santa Catarina (SC) and Rio Grande do Sul (RS) were used. Fractures and bruising were recorded together, representing the most prevalent welfare problem, followed by skin lesion or inflammation. In PR, progressive increases on injury, arthritis, ineffective bleeding, and air sacculitis condemnation may reveal important welfare aspects. High correlation between AWI within PR was more commonly observed than in RS and SC, perhaps as a result of earlier implementation of local meat inspection standardization. Principal component analysis showed changes on condemnation data pattern in PR after standardization, pointing injury and Escherichia coli problems as the main causes for condemnation related to animal welfare. There is considerable potential to improve animal health and welfare surveillance using meat inspection structure that is already in place for food safety purposes, provided that the competent authority harmonizes the procedure of meat inspection among the States, sets specific animal welfare outcomes to be monitored, and integrates condemnation, transport and flock data. It seems crucial to update data collection to establish a routine that allows risk analysis regarding both food safety and animal welfare. In this regard, cooperative work between Federal Inspection and companies seems an interesting approach to promote transparency of the production processes, which would benefit society and animals.
Highlights
Brazil is the second largest broiler chicken producer in the world
In 2015, about 5.2 billion broiler chickens were slaughtered in establishments under the Federal Inspection Service (SIF) of the Ministry of Agriculture, Livestock and Food Supply (MAPA), and there is a projection of a 46.4% increase in chicken meat production by 2023
Considering the 27 States in Brazil, there are 18 that produce broiler chicken meat, of which, Paraná accounts for one third of total national production
Summary
In 2015, about 5.2 billion broiler chickens were slaughtered in establishments under the Federal Inspection Service (SIF) of the Ministry of Agriculture, Livestock and Food Supply (MAPA), and there is a projection of a 46.4% increase in chicken meat production by 2023. In the European Union (EU), Directive 2007/43/ CE (European Commission, 2007), on the protection of chickens kept for meat production, sets out compliance inputs for poultry farms, such as maximum stocking density, minimum lighting intensity, and air quality parameters. Outputs such as mortality and meat inspection data are considered with the purpose of establishing maximum stocking density values. Dermatitis, parasitic infections and systemic illness are measured by the official veterinarian at the slaughterhouse to identify signs of poor welfare
