In literature on olive oil mills and occupational health and safety, in particular noise exposure, mention must be made of two studies by Parejo-Moscoso et al. (2012, 2013), who pointed out that “the risk of noise exposure, characteristic of the sector, is only assessed in 73% of the olive oil mills examined, and of this 73%, only 75% of the olive oil mills implement a protocol to adequately monitor their employees' health in relation to noise exposure.” Among the most hazardous work conditions, Rubio-Romero et al. (2013) highlighted the high level of noise to which workers from this sector are exposed.
