Integration of water, sanitation, and hygiene program with biosecurity: A One Health approach to reduce the prevalence and exposure of antibiotic-resistant bacteria in the livestock community

Abstract

The global spread of antibiotic resistance poses a significant threat to public health and is one of the main causes of this problem. Livestock farming plays a significant role in the horizontal and vertical transmission of treatment-resistant genes and bacteria. These processes involve contact with agricultural products and the environment, raising concerns for public health, and farming communities. The farming community is composed of a staggering 608 million farms worldwide, and their livelihood depends heavily on livestock farming. To address this issue, a multidisciplinary One Health approach focusing on integrated monitoring and intervention for humans, animals, and the environment is essential. Water, sanitation, and hygiene (WaSH) programs have the potential to significantly reduce the risk of exposure to antibiotic-resistant bacteria, particularly extended spectrum beta-lactamase (ESBL) Escherichia coli, by obstructing the transmission route between humans and animals. Additional risk reduction measures for ESBL E. coli infection in animals include vaccination and biosecurity program implementation. Water, sanitation, and hygiene and biosecurity measures must be combined to maximize the effectiveness of the One Health program. Therefore, this study aimed to describe recent advances in biosecurity and WaSH interventions in the livestock environment, analyze the effects of these interventions on human and animal health, and investigate potential future scenarios within the quantitative microbial risk assessment framework. This study used an integrative literature review through searches of four databases, a review of World Health Organization documents through websites, and an examination of relevant texts from previously obtained reference lists. Although hygiene and sanitation are often combined, there is still a lack of quantitative evaluation of the efficacy of integrating WaSH with biosecurity in livestock. In addition, the integration of the WaSH program with biosecurity has potential as a One Health intervention in the coming years.
