Abstract

People are exposed to environmental noise each day. It may be annoying, cause stress, induce hormonal changes, and negatively affect long-term health. This study aimed to determine the effects of environmental noise on annoyance, perceived stress, stress symptoms, and urine cortisol in people living in a selected area. This cross-sectional study was conducted from April to October 2022 on 142 participants. Urine samples were collected to determine cortisol levels, and perceived stress, stress symptoms, and environmental noise annoyance were evaluated using questionnaires. Stress symptoms correlated with traffic, industrial, and community noise, but not aircraft noise. Community noise correlated most strongly with all stress symptoms. Only community noise exposure was correlated with perceived stress. People reported that industrial and community noise affected their health and daily activities. Cortisol correlated with only traffic noise annoyance. Environmental noise was associated with stress symptoms and stress hormones. In brief, sound level is not the onlyindicator of stress or health impacts, but annoyance and concern over the effects of noise may negatively affect stress and health.

Abstract

This study examined the risk of Salmonella spp. exposure among chicken farm workers by evaluating occupational health management practices. The probability of exposure was determined by assessing the number of contamination points. Sampling for Salmonella spp. contamination was conducted at 7 and 45 days of chicken batches across five areas, alongside evaluation of worker behaviors to assess exposure risk. Three of the 12 large closed-system farms, each housing >10,000 chickens, were selected. Results indicated that boots were the most contaminated items. Workers generally adhered to habitual boot-wearing, which reduced the risk of exposure. Moderate levels of workers' exposure prevention practices, combined with good farm environmental management, resulted in low contamination levels. Reducing Salmonella spp. accumulation was therefore crucial for minimizing contamination. In brief, the chicken farm workers in Phatthalung face measurable risks of Salmonella spp. Exposure reduction, strengthening occupational health management, and improving workplace practices are essential to mitigating these risks and protecting both farm workers and the broader community.
