A elevada preocupação com a segurança dos alimentos, relativamente ao consumo de
carnes provenientes de animais doentes e à transmissão de doenças ao Homem através
destas carnes, levou à necessidade de estabelecer regras específicas de organização dos
controlos oficiais de produtos de origem animal destinados ao consumo humano. Este
controlo oficial, mediante as atividades de inspeção sanitária, visa garantir que toda a carne
e produtos alimentares derivados da mesma, chegam ao consumidor nas condições
sanitárias adequadas.
Neste contexto, este trabalho teve como principal objetivo a determinação das causas de
rejeição completa de carcaças de bovino, dos conjuntos de vísceras vermelhas, dos
conjuntos de vísceras brancas e de pulmões, coração, fígado e rins, mediante o
acompanhamento das ações da equipa de inspeção sanitária presente no matadouro
Santacarnes S.A.. Com este trabalho foi possível apurar quais as causas de rejeições mais
comuns através da observação e registo, tanto fotográfico como documental. O tratamento
dos dados incidiu na determinação das frequências (%) para análise da incidência entre
causas e número de rejeições. Durante o período de estágio (Fevereiro a Julho de 2012)
foram abatidos e inspecionados 7191 bovinos. Com base nestes registos, no mesmo
período, verificou-se a rejeição de 28 carcaças de bovino e a maior incidência de rejeições
observou-se em fígados, rins e pulmões (27,93%). A principal causa de rejeição da
totalidade da carcaça foi a pneumonia purulenta (0,14%). A maior incidência de rejeição de
fígados deveu-se a abcessos (4,55%). Os rins foram rejeitados, na sua maioria, pela
presença de cálculos renais (1,59%). Quanto aos pulmões, a principal causa de rejeição
resultou da existência de: i) um histórico de animais suspeitos positivos à prova da
intradermotuberculinização e/ou; ii) de lesões suspeitas detetadas em post mortem,
associado à presença de Mycobacterium bovis ou tuberculosis, isolado na exploração de
proveniência desses animais (5,55%).
ABSTRACT - The concern about food safety regarding consumption of meat from sick animals and disease transmission to humans led to establish specific rules in order to improve official controls on animal products for human consumption. This official control, through sanitary inspection activities, allows that meat and meat products reach the consumer in the right sanitary conditions. Main goal of this work was to determine the causes of rejection of beef carcasses, of groups of red and white viscera, of lungs, heart, liver and kidneys as the result of sanitary inspection team actions at Santacarnes S.A. slaughterhouse. This actions allowed to avoid the consumption of harmful meat and viscera to health and human welfare. It was possible to determine the most common causes of rejections through the observation and registration (photographic and documentary) of these. Data analysis were focused on determining the frequency (%) of the rejection causes. During trainee period (February to July of 2012) were slaughtered and inspected 7191 animals. Based on these registrations, 28 beef carcasses were rejected and high numbers of rejections were observed in lungs, liver and kidneys (27,93%). The main cause of beef carcasses rejection was purulent pneumonia (0,14%). The major cause of rejection of liver was due to abscesses (4,55%). Kidneys were rejected mostly by urinary calculi (kidney stones) (1,59%) and lungs presented the highest number of rejections related with official confirmation of suspect animals, positive proof of intradermal or suspicious lesions detected in post-mortem, and in which has been isolated Mycobacterium bovis or tuberculosis in the farm of animals provenience (5,55%).
