1. Introduction
In resource-limited settings, there is a high usage of antibiotics in food-producing animals for preventive, metaphylactic, therapeutic, and growth promoters, especially with the modernization and commercialization of the poultry industry [
1,
2,
3]. The misuse of antibiotics has been regarded as a major driver of antimicrobial resistance [
4]. In addition, it poses a risk of zoonotic transmission as humans may acquire antibiotic-resistant bacteria from animals, particularly poultry, by direct contact with them and their byproducts (meat or eggs) during handling and slaughter, by consuming infected food (farm-to-fork transmission), or by animal waste contaminating the environment [
4,
5,
6,
7]. Several studies have provided evidence of the transfer of antibiotic resistance from animals to humans via the food chain [
8,
9,
10].
Nepal, a low-income country in Southeast Asia, has a population of 29.19 million out of which 60.4% of its citizens are engaged in agriculture and livestock production [
11]. Agriculture contributes 25.83% of the national gross domestic product (GDP), while the livestock sector alone contributes 13% of the GDP and 27% of the agriculture GDP [
11]. In Nepal, poultry farming is rapidly expanding, and the country is self-sufficient in the production of chicken meat and eggs [
12]. Around the Kathmandu Valley, there has been a report of high antibiotic usage, including reserve antibiotics for human medicine [
13]. Of the total veterinary expenditure in Nepal, antibiotics accounted for 13% in 2008 and this rose to 50% in 2012 [
14]. Another study in Nepal revealed that 46% of the veterinary drugs were prescribed by a pharmacist and 12% were due to farmers’ self-demand [
2].
Currently, there are no guidelines on prudent antibiotic usage in poultry and food animals in Nepal, there are no laboratory strategic plans for guidance and governance to national laboratories, and most poultry farmers lack adequate training in poultry husbandry, including biosecurity [
15]. Hence, proper guidelines on the prudent use of antibiotics in food animals, the establishment of surveillance programs, and biosecurity training programs for livestock farmers, technicians, veterinarians, and the general public on the rational use of antimicrobial drugs can reduce the burden of AMR in Nepal [
2]. Baseline data on the knowledge, attitude, and practice of antibiotic use and AMR can play an important role in the design of these training programs that should focus on the rational use of antibiotics, good management practices, and the production of wholesome poultry products [
16,
17,
18]. Therefore, this study evaluated the knowledge, attitude, and practices regarding antibiotic use and resistance among poultry farmers in different regions of Nepal.
3. Discussion
In the global efforts to control antimicrobial resistance (AMR), a lack of sufficient strategies to address the indiscriminate use of antimicrobials and inadequate application of the available laws and policies are the major constraints in Nepal. In the context of Nepal, relatively modest investments in intervention strategies to fight AMR are immediately required [
20]. In Kathmandu (the capital city of Nepal), 90% of poultry farms (Broiler) use antibiotics either for treatment or prophylaxis [
13,
21].
The knowledge level of participants regarding different issues of AMU and AMR in our study was relatively high. Similar findings were reported in a study conducted in Bangladesh [
22]. However, the level of knowledge was relatively low in studies conducted in Cameroon and India [
23,
24]. The level of knowledge of participants in our study could be higher as a higher proportion of them were from some of the developed districts of Nepal including Kathmandu. The majority of the population in our study was aware of antibiotics and their use. However, only half of the participants knew about AMR and ways to reduce it. The result suggests the presence of a knowledge gap between prudent AMU and AMR. Participants aged 45 and above had significantly lower knowledge levels compared to farmers aged 18–29, which is similar to the study conducted in Bangladesh [
22]. This may be due to the increasing literacy rate and awareness of AMR from social media. Youths have more access to social media and are more flexible in accepting and following new issues like AMR. Additionally, the male population had significantly higher levels of knowledge compared to females. In Nepal, major business entrepreneurship is male-dominated, and compared to females, a high proportion of males are in decision-making positions, which could have influenced the knowledge level across the genders [
25,
26]. Furthermore, the low participation of women in technical and vocational training, compared to males, may have influenced the lower KAP values in females [
27] Again, lesser knowledge of the female population could be a major challenge to reducing AMR in Nepal as, unlike decision-making, the majority of women are involved in day-to-day activities related to livestock (including poultry) like feeding and cleaning [
28,
29]. A lower participation (30%;
n = 179) of women was observed in our study, which depicts the situation of agriculture entrepreneurship in Nepal. In the current study, the knowledge level varied according to the educational level, and participants with higher education had significantly higher odds of having better knowledge status. Similar results were obtained in the studies in Bangladesh [
22], Romania [
30], Hong Kong [
31], Turkey [
32], Vietnam [
33], Germany [
34], and five African countries [
35]. This suggests that education plays a vital role in making people aware of the concepts of AMU and AMR. Our study showed that farmers from the Kailali district had significantly higher levels of knowledge compared to others. This could be due to the rapid growth of the poultry sector in Kailali over the last decade, with a large number of big poultry farms, hatcheries, and feed companies [
36].
Like knowledge, the study population had a good attitude toward AMR and AMU. The average score of the participants was 72.5%, which again could be attributed to the sampling location (major poultry hubs like Chitwan, Kailali, and Kathmandu). The majority of the participants agree on the fact that advice from the veterinarian is necessary before the use of antimicrobials on their farms. Similarly, most of them believe that good hygiene, biosecurity, vaccination, education, and awareness can play a vital role in reducing the problem of AMR. This is overwhelming, but we must keep in mind that, still, a considerable number of people do not agree with these facts. Addressing the problem of AMR is never an individual task and requires a collaborative effort from all the stakeholders [
37,
38,
39]. Again, the level of attitude also varied among the various demographic variables. Males again had better attitudes when compared to females and participants of the Kailali districts had better attitudes toward AMU when compared with participants of other districts. The attitude levels were very similar to the knowledge level as they had a significant positive correlation between them. This association is also attributed to the fact that knowledge level could have influenced the level of attitudes in participants, as similar results were obtained in previous studies too [
22,
40]. However, unlike knowledge levels, it is rather surprising to see the lower level of attitude among farmers of Kathmandu and Chitwan compared to Syangja. This provides us with knowledge of the fact that, despite having good knowledge, people of so-called developed districts do not necessarily show positive attitudes. This is where strong federal, provincial, and local level rules and policies against AMR should act.
In our study, a clear transfer of knowledge and attitude into practice was not observed. The average practice score was 50.6% compared to 65.1% and 72.5% of knowledge and attitude scores, respectively. In this study, 11.24% of the respondents were involved in self-treatment and 29.09% did not obtain prescriptions from veterinarians before buying the antimicrobials. These practices hold significant public health risks and promote the development of antimicrobial resistance [
2,
41]. Additionally, only 26% of the respondents visited veterinary laboratories to perform antimicrobial susceptibility tests (ASTs) before using antimicrobials in their farms. As several antimicrobials are resistant to different types of pathogens, the use of antimicrobials without performing ASTs can elongate the duration of treatment and on multiple occasions could force the farmer to try multiple antimicrobials [
21,
42,
43]. In this study, only 20.33% of the study population maintained the withdrawal period, which is less than half the value reported by a recent study held in the Chitwan district of Nepal [
44]. Furthermore, almost half of the study population either used the antimicrobials for a few days or stopped using them as soon as the symptoms subsided. The inappropriate use of antimicrobials is always a leading factor in the development of AMR [
45,
46,
47]. Despite the focus of the Government of Nepal on ensuring no antibiotics are found in feed supplements, almost half of the study population used antimicrobials primarily either for growth or for both growth and treatment [
2,
44]. Just like for knowledge and attitude, male participants from the Kailali district raising layer poultry had the highest practice level compared to others. However, education was statistically non-significant with the practice score. This is a matter of surprise as the previous studies showed improved practice levels with higher educational levels of their participants [
22,
48]. This could be attributed to low levels of practice in our study as well as provide an important insight into the fact that education can influence knowledge and attitude but not necessarily practice if other factors like regulations and awareness do not act in place.
In the current study, poultry farmers used 11 classes of antimicrobials. Out of them, four classes of antimicrobials, namely macrolides, cephalosporins (first and third generation), and polymyxins, are the highest priority as they are critically important antimicrobials in human medicine [
49].
The World Health Organization suggests not to use these highest priority critically important antimicrobials for treatment and control of disease in food-producing animals [
50]. The easy availability and over-the-counter (OTC) sale of these antimicrobials in the country makes it more difficult to stop their haphazard use. A recent study conducted in the Kathmandu Valley of Nepal had similar findings [
21]. Additionally, nearly half of the population in our study revealed that they experienced treatment failure with some of the antimicrobials in their farms. This is a very concerning fact and reflects the situation of AMR in Nepal.
Overall, the KAP level of participants in this study was more or less similar to previous studies [
24,
44,
51]. The current situation of understanding and using antimicrobials in Nepal should be upgraded to ensure a safe direction toward the use of antimicrobials and prevent AMR. Antimicrobial resistance carries a significant public health risk and can significantly hinder the treatment system in both humans and animals. Additionally, low- and middle-income countries (LMICs) like Nepal are the epicenter of increasing public health threats [
39]. As revealed by our study, still a considerable part of the population does not know that vaccination and biosecurity can decrease the burden of antimicrobial use and hinder the development of AMR. Previous studies have highlighted the increased risks of AMR in farms with poor biosecurity and the role of vaccines in reducing the occurrence of infectious diseases and antimicrobial use [
52,
53,
54,
55]. Furthermore, the technical knowledge regarding antimicrobial use and its resistance should be enhanced among female farmers of Nepal. A mutual decision-making environment with the involvement of females in the business discussion may be essential to reduce the disparity of KAP levels among genders in Nepal.
Hence, regular awareness programs involving all the related stakeholders through multiple streams and the development of a new framework to fight AMR are crucial in Nepal. Despite the commencement of laboratory surveillance of AMR in 1999, there is a limited number of comprehensive studies on AMR in Nepal [
56]. In 2014, the Alliance for the Prudent Use of Antibiotics (APUA) drafted the National Antibiotics Treatment Guidelines for Nepal, which was approved by the Ministry of Health and Population (MOHP) [
57]. The guidelines were overwhelming but primarily focused on human health. As the animal sector in Nepal also contributes significantly to the development of AMR, the Government of Nepal should work in a One Health framework during the planning and drafting of the guidelines and policies. In 2016, the Government of Nepal launched the National Antimicrobial Resistance Containment Action Plan to protect Nepalese people from related risks of AMR [
56]. However, for more than 6 years, very little has been achieved [
58]. In the middle of all these dilemmas and challenges, Nepal should force a way out to join the battle against AMR by the effective application of the available policies and by developing alternative approaches to address AMR in a One Health framework.
Like any research, this study has certain limitations that should be taken into consideration. Firstly, the data were collected through personal interviews, which introduces the possibility that some farmers may have provided socially desirable answers, potentially affecting the accuracy of the responses. Secondly, the snowball sampling method employed in this survey could have influenced the results, as it relies on participants referring others who may share similar characteristics or opinions. This could introduce bias into the sample. Thirdly, this study did not explore the difference in KAP levels in rural, urban, and peri-urban areas of the study area, which could potentially have impacted the scores. However, we suggest that future researchers include this demographic variable in their study. Finally, it is important to note that the participants in this study were primarily from the major poultry areas of Nepal, such as Chitwan, Kathmandu, and Kailali. Therefore, the knowledge, attitude, and practice (KAP) levels observed in this study may not necessarily reflect the overall KAP levels of the entire country.
