Chile’s first odour regulation for pig farming, enacted in 2023, prompted an evaluation of its social impact.
A survey in four affected regions showed significantly higher annoyance levels than in control areas, with women reporting more behavioural adaptations. While no gender differences were statistically significant, the study highlights the need for larger samples and better implementation strategies. The methodology could also be applied to assess odour regulations in other industries.

Abstract
The first odour regulation in Chile, applicable to the pig farming industry, came into force in 2023, generating the need to evaluate its impact on the public's perception of annoyance. This study analyses the results of the application of the odour annoyance survey, based on NCh 3387:2015, in four areas of the country affected by odorous emissions from pig farms. The findings indicate that impacted areas have significantly higher levels of annoyance compared to control areas. No statistically significant gender differences were found, although women reported greater behavioural changes as a coping strategy. It is recommended to expand the sample surveyed and improve the implementation strategies, considering the context of insecurity in the country. Finally, the methodology used could be replicated in future studies to evaluate the effectiveness of odour regulations in other industrial sectors..
