Brazil was rated the fourth leading producer and exporter of pork meat in the world. The aim of this study was to evaluate the temperature of the hands of pig slaughterhouse workers and its relation to the thermal sensation of the hands and the use of a cutting tool. The study included 106 workers in a pig slaughterhouse. An infrared camera FlirThermaCAM E320 (Flir Systems, Wilsonville, OR, USA) was used to collect the images of the dorsal and palmar surfaces of both hands. A numerical scale was used to obtain the thermal sensation. Chi-square test, Pearson correlation and Student's test or Wilcoxon were used ( ≤ 0.05). The majority of workers felt cold in the hands (66%) and workers who used the knife felt the coldest. There was an association between the thermal sensation and the use of knife ( = 0.001). Workers who used the tool showed correlation between the thermal sensation and the temperatures of the left fingers, with a difference between the temperatures of the right and left hands of those who used the knife ( ≤ 0.05). The hands (left) that manipulated the products presented the lowest temperatures. Findings indicate that employers of pig slaughterhouses should provide gloves with adequate thermal insulation to preserve the health of workers' hands.
巴西被评为世界第四大猪肉生产国和出口国。本研究的目的是评估生猪屠宰场工人手部的温度，及其与手部热感觉和切割工具使用之间的关系。该研究纳入了一家生猪屠宰场的106名工人。使用一台红外热像仪FlirThermaCAM E320（美国俄勒冈州威尔逊维尔市的菲力尔系统公司）采集双手背侧和掌侧的图像。采用数字量表来获取热感觉。使用了卡方检验、皮尔逊相关性分析以及学生t检验或威尔科克森检验（P≤0.05）。大多数工人感觉手部寒冷（66%），且使用刀具的工人感觉最冷。热感觉与刀具使用之间存在关联（P = 0.001）。使用工具的工人热感觉与左手手指温度之间存在相关性，使用刀具的工人左右手温度存在差异（P≤0.05）。操作产品的手（左手）温度最低。研究结果表明，生猪屠宰场雇主应提供具有足够隔热性能的手套，以保护工人手部健康。
