Abstract
ABSTRACT
In Brazil, meat inspection occurs in a decentralized manner and consists of three types: (i) federal inspection (SIF), (ii) state inspection (SISP), and (iii) municipal inspection (SIM). The objective of this work was to discuss the three current inspection systems through the apparent prevalence of bovine brucellosis, a zoonosis that has an eradication program implemented by the Brazilian government. Nine abattoirs from federal, state, and municipal inspection systems were assessed and 1,490 animals were sampled. Serology for brucellosis was determined by the rose bengal test and the complement fixation test. The overall apparent prevalence (and 95% confidence interval) of brucellosis was 2.2% (1.5 to 2.9%). Apparent prevalence stratified by inspection system for SIF, SISP, and SIM was 0.4% (0.0 to 0.9%), 2.0% (0.8 to 3.2%), and 4.3% (2.5 to 6.1%), respectively. Multivariable logistic regression analysis revealed the odds ratio for finding an animal positive for brucellosis among inspection systems. A statistical difference (P < 0.0015) was observed among surveillance systems, with SISP × SIF, SIM × SISP, and SIM × SIF having an odds ratio of 4,996, 2,304, and 11,494, respectively. Hence, the need for increasing official surveillance in state and municipal inspection systems seems to be necessary and could assist in the surveillance of bovine brucellosis and other diseases of interest to the federation. In addition, an increase in official presence would help to improve the selection of slaughtered cattle during ante- and postmortem inspection, with consequent impact on food safety and public health.
