Ergonomic risk evaluation of the manual handling task of bovine quarters in a Brazilian slaughterhouse

Abstract

In 2017, Brazil was the largest exporter and the second largest producer of beef in the world, besides the sixth sector that causes most occupational diseases in this country. Thus, this study aimed to analyze the ergonomic risk of the manual handling task of bovine quarters in a slaughterhouse. The risk-assessment model presented in ISO11228-1 was employed. However, the five steps were unfulfilled. Conforming to monthly production data, each one of the seven workers registered handled 282 pieces per day (33.8 ± 22.8 kg/piece). Some inappropriate work conditions can be highlighted: handled weights were high per worker, per day; floors were uneven and slippery; handling with one hand and standing posture was restricted. All the interviewed workers (n = 6) perceived the exertion to accomplish the task as 8 (very hard+), along with feeling back pain. The manual handling task of bovine quarters was unacceptable and needs adaptation, as there were many ergonomics risk factors.
