This study quantitatively investigated the physical exposure in the upper extremities of poultry processing operators, by electromyography (EMG) and psychophysical methods. Results showed that all three poultry processing jobs had high loads on the forearm flexor and extensor muscles. Loading on the shoulder region may not be a major concern for many of the operators. However, some individual operators may still be exposed to high shoulder loads possibly due to the mismatch between the workstations and the individual operators.
