Introduction

Food safety remains a challenge in developing nations, including Ethiopia, where dairy products are known to be contaminated with foodborne pathogens. Limited food safety interventions studies for improving food safety along the food supply chain have been conducted. The objective of this intervention study was to improve the knowledge, attitudes, and practices (KAPs) of women dairy farmers in the central highlands of Ethiopia by developing and delivering training customized to their education level.

Methods

A total of 120 dairy women farmers were recruited from local milk cooperatives and milk collection centers at four study sites. Training materials on clean milk production and hygienic milking practices were developed for an audience that may not be able to read or write. The 3-day curriculum was delivered using theoretical lecturing, video presentation, practical activities, and handouts, and learning was assessed with a questionnaire and checklist.

Results

The study indicated that women dairy farmers improved their knowledge, attitude, and practices relating to quality milk production. However, milk shade assessments of individual farmers identified many important risk factors for clean milk production that were due to infrastructure issues.

Discussion

The effectiveness of the training materials and approach was supported by the increase in KAPs assessment scores from pre-training to post-training for all study sites. Comparisons of the training outcomes and evaluation results of milk shades were found counterintuitive, which revealed the complexity of food safety interventions. Customized food safety training is effective but should be combined with dairy farming infrastructure improvements to achieve the goal of clean milk production at farm level.

      Introduction

      Foodborne illness remains a challenge in least developed countries due to the increased consumption of perishable crop and animal products, and the complex nature of the food value chain (Grace, 2015). It affects over 90% of the populations in low-and middle-income countries (LMICs), and around 40% of this burden affects children under the age of five. In 2010, dairy products and animal-sourced food consumption contributed 4 and 12% of global foodborne disease burdens, respectively (Havelaar et al., 2015; Grace et al., 2020; Grace, 2023).

      Ethiopia has the potential for cattle production due to its ideal climate, however, milk production in terms of quantity and quality is low (Gebreselassie, 2019). In developing countries, lack of knowledge, technology, social barriers, and infrastructure are major constraints for high quality milk production (Ledo et al., 2019). As a result, dairy products serve as a significant medium for the spread of foodborne and spoilage organisms (Ntuli et al., 2023; Fereja et al., 2023), and consumption of dairy products without proper heat treatment may pose health risks to humans (EFSA Panel on Biological Hazards (BIOHAZ), 2015).

      Previous studies reported that dairy products in Ethiopia, such as milk, yogurt, and cottage cheese, are contaminated with foodborne pathogens such as Salmonella spp., Listeria spp. and Listeria monocytogenes, E. coli O157:H7, and Campylobacter spp. (Keba et al., 2020; Bedassa et al., 2023; Mengstu et al., 2023; Asfaw et al., 2023; Hawaz et al., 2023; Hunduma et al., 2023). Studies indicated that potential risk factors of foodborne pathogens and associated public health risks were very high in the country, which can cause human diseases ranging from gastrointestinal disturbances characterized by diarrhea and vomiting to life-threatening illnesses (Bintsis, 2017).

      Major factors of safe milk production at the farmer level are poor hygienic practices, lack of food-grade milk equipment, clean water sources, milk cooling, and animal health, including the teat and udder health of milking cows (Amenu et al., 2013; Abunna et al., 2018; Bereda et al., 2018; Gwandu et al., 2018; Kebede et al., 2019).

      Women perform most of the dairy farming activities and, therefore, contribute to the major risk factors in producing good quality milk (Getachew and Tadele, 2015; Kinati and Mulema, 2018). However, women farmers have less access to education, dairy farm management and animal husbandry, and training opportunities (Tassew and Seifu, 2009; Yuya, 2018; Didanna et al., 2019). In 2022, Garsow et al. published a paper that described the importance of gender-sensitive food safety initiatives in reducing foodborne illness and improving family health.

      Capacity building and creating food safety awareness for women farmers could improve knowledge of individuals and communities and long-term food safety system partnerships in the food supply chain (Gallina, 2016; Lindahl et al., 2018). The objective of this intervention study was to improve the knowledge, attitudes, and practices (KAPs) of women dairy farmers in the central highlands of Ethiopia by developing and delivering training customized to their education level. Changes in KAPs indicators were measured by pre-and post-training self-assessments and an evaluation of milk shade environments by the trainees. The study showed the training improved KAPs indicators of the women farmers, but there were infrastructure issues that provided challenges with improving milk quality at the farm level.

      Materials and methods Study area

      The study was conducted in the Oromia region, in the central highlands of Ethiopia. Four training areas were selected based on the potential of milk flow to the capital city, Addis Ababa: Wolmera, Bishoftu, Asella, and Selale (Figure 1). The study areas were within a radius of 175 km from the capital city and at altitudes of 1850 to 4,130 m above sea level. The mean annual rainfall varies from 866 to 1800 mm, and the annual average temperature ranges from 18.7 to 22.5°C (CSA, 2019).

      Inclusion and exclusion criteria

      Dairy farmers, within the study area identified above, who were female, over 18 years old, held lactating cows and sold raw milk to milk cooperatives and/or direct-to-consumers were eligible to participate in the study. Farmers who were outside of Wolmera, Bishoftu, Asella and Selale areas or commercial and organized farms were excluded from participating in the study.

      Sample size and selection process

      The number of the participants needed was calculated to achieve 80% of the power to detect a change (α = 0.05), which was determined to be 80 dairy women farmers. To protect against dropouts, loss of follow-up, and other sources of missing data, a total of 120 women dairy farmers were purposefully selected in equal proportions from the Wolmera, Bishoftu, Asella, and Selale areas to ensure sufficient power for analysis.

      Lists of dairy producers were collected from milk cooperatives and milk collection centers in the four study sites. A total of 280 dairy farmers were screened from the original lists of 530 producers based on dairy women farmers and delivering milk to the milk collection centers or cooperatives. Then, 120 dairy women farmers were randomly selected from the four sites, and 30 dairy women represented each site (Figure 2). Farmers were invited to the training with the help of developmental agent workers by informing training objectives and incentives.

      Training materials and curriculum

      A training guide, teaching video, and handouts on improving milk quality and safety were developed in English by scholars from the Pennsylvania State University, the Ethiopian Institute of Agricultural Research, Addis Ababa University, and Hammer Video Production PLC. The materials were adapted to local contexts and translated to the ‘Afan oromo and Amharic’ local languages.

      The contents of the guide, video, pictures, and handouts were developed for some trainees who might not be able to read or write, and there would be a range of literacy levels at all training sessions. Each visual image contained one or two key concepts that were presented with simple words and pictures or a graphic image. Complex concepts were broken down into several slides or images, rather than presented as a text-heavy list. Key concepts in sanitation were reinforced with repetition during lectures, by inclusion of real-life examples, demonstrations, hands-on activities such as hand washing in the classroom and udder preparation on the farm, and in the take home handouts.

      The curriculum included three consecutive days at each site to cover the theoretical lectures, practical sessions, teaching videos, and assessments. The training started at 10:00 am and ended by 4:00 pm to allow the women to attend to their daily farm and family responsibilities. We have provided breakfast, lunch, transportation facilities, and time compensation costs for the effectiveness of the training and covering their time, respectively.

      Classroom sessions were conducted using a laptop computer connected to a projector, and with the aid of flip charts and markers. Question and answer sessions were included to encourage participation and comprehension, and two to three participants were asked to give a recap of the prior day’s activities before the commencement of second and third training days.

      Topics included the importance of clean milk production, factors affecting clean milk production, the basic principles of cleaning and disinfecting, methods to produce clean water, proper procedures for hand washing, and proper hygienic milking steps.

      Practical activities were conducted in the classroom and at selected dairy farms near the training sites to demonstrate procedures and to assess the knowledge, attitudes, and practices of the women farmers. Proper hand washing practices were demonstrated by the instructors, and then the cleaning efficiency of participants that washed hands with and without soap was evaluated using Glo-Germ™ gel and a UV lamp.1 Proper steps in cleaning and disinfection of milk equipment were demonstrated by instructors, and then the cleaning efficiency of individual and group participants that washed milk equipment only using cold water or cold water followed by hot water was evaluated with Glo-Germ™ powder and a UV lamp (see text footnote 1, respectively).

      Appropriate milking procedures were demonstrated by the instructors at the dairy farm and included cleaning udders, pre-dipping of the teats, mastitis checking, full-hand milking, post-dipping of the teats, and milk filtering. The women farmers were given an opportunity to practice these techniques during the session.

      Intervention training and farmer assessments

      Two training sessions, with 15 women farmers each, were conducted at each of the four study sites (Figure 1). Hand and equipment washing skills of trainees were assessed during the practical sessions using Glo-Germ ™, as described above.

      The knowledge, attitude and practices (KAPs) on hygienic milk practices of women dairy farmers were assessed using semi-structured questionnaires before and after the intervention training program. The questionnaires contained approximately 10 questions covering clean milk characteristics, risk factors for contamination, cleaning and disinfecting theory and practice, and hygienic milk practices (Supplementary material; Appendix 1).

      Milk shade assessment of individual farmers was done at the end of the training using prepared standard checklists (Supplementary material; Appendix 2). The milk shade was evaluated on basic dairy environment factors and hygienic practices. The dairy environment was evaluated in terms of the personal hygiene of the milker, availability of clean water sources, cleanliness of milking areas, and appropriateness of milking and milk handling equipment. Dairy farmers were evaluated based on standard training provided for them on milk filtering and cooling, teat dipping and mastitis checking practices, availability of clean towels, and sanitizing detergents. Then, instructors scored each element of dairy environments using an evaluation method rated as 0 = absent, 1 = insufficient, 2 = fair, 3 = good, 4 = very good, and 5 = excellent.

      All questionnaires and checklists were translated to ‘Afan oromo and Amharic’ local languages. Instructors and assistants were available to help trainees that were unable to read and/or write complete the questionnaires and checklists.

      Data analysis

      Statistical analysis was done using statistical software SPSS version 22 (SPSS, Inc., Chigago, United States). Basic descriptive analysis was conducted of the socio-demographic profiles of the participants, and pre-and post-test data were compared using a paired T-test. Milk shades observation data was analyzed by using a nonparametric chi-square test at p ≤ 0.05.

      Results Intervention training

      The intervention training sessions were delivered in collaboration with Holeta Agricultural Research Center, Ethiopian Meat and Milk Development Institute, Kulumsa Agricultural Research Center, and Selale University from 1 February to 30 March 2022.

      The socio-demographic profiles of dairy women farmers that participated in the hygienic milk production intervention training sessions are shown in Table 1. More than half (59%) of the trainees were between the ages of 31 and 50, and the other trainees were approximately equally proportioned (20%) between the age groups of 18 and 30 and above 50 years of age. Most of the trainees completed secondary school (34%) or primary school (33%), while 15% of the attendees who had no formal education. Approximately 12% of the trainees a had basic adult education, but very few trainees (less than 6%) completed college or had any higher education. The largest populations of trainees were from rural areas (44%), but a sizeable amount was from urban (37%) and peri-urban areas (19%). The majority of trainees obtained their primary source of income of from dairy farming (48%), followed by mixed crops and livestock farming (17%) and crop farming (12%).

      The practical sessions with demonstrations of proper washing techniques and a novel assessment method like Glo-Germ ™ was an engaging learning experience for the trainees. Figure 3A shows dairy farmers practicing proper hand washing steps by applying enough soap to their hands, and Figure 3B shows hand washing efficiency being evaluated by instructor. The farmers were so motivated by the method and its simplicity that they started to evaluate themselves on their hand washing skills, even in absence of the instructor (Figure 3C), thus demonstrating a significant change of attitudes in proper hand washing practices among the participants during the training sessions.

      The hygienic milking practical sessions illustrated new concepts for the trainees. Again, the instructors demonstrated the proper procedures, and the trainees were given time to practice. Figure 4A shows trainees practicing teat dipping, including cleaning and disinfecting teats with iodine solution. Figures 4B,C are the instructor demonstrating mastitis checking and full hand milking, respectively. During the practical sessions, we observed the absence of teat dipping with anti-microbial agents, checking for mastitis, and proper full hand milking practices by the trainees. We learned during the milk shade assessment (below), that very few farmers had experience with hygienic milking practices.

      Trainee assessments

      Trainees were assessed on their knowledge, attitudes, and practices of hygienic milking concepts through observations during practical sessions as reported above and using a milk shade checklist and a pre-and post-training questionnaire.

      We observed in the practical sessions that trainees had little experience with hygienic milking practices, and this was supported by the milk shade risk factor assessment that showed 98.3% of farmers had no experience with teat dipping or mastitis checking practices (Table 2). Cleaning of the milking area also scored low, with 39% rated fair and 26% rated insufficient. Scores for cleaning equipment and using towels were higher, with 26 to 35% of the ranked as good or very good, and 23 to 38% of the scores for cooling milk, using detergents, and filtering milk were ranked as very good or excellent.

      The assessment of risk factors in the milk shed environment showed that approximately 25 to 48% were ranked insufficient on personal hygiene, water source, milking area, dairy house, and milking equipment (Table 3). The milk storage areas were rated highest; with 55% scoring very good and 26% had a score of good. Other areas with high ratings included milk equipment (35% very good, 23% good), and milking area (30% good). Water source was scored insufficient at 39.5%% of the milk sheds.

The pre-training score means ranged from 5.6 to 7.5 at all training sites, which increased to 9.1 to 9.6 for the post-training assessment. The mean score of the pre-training KAPs results increased from 6.7 to 9.4 for the post-training assessment, which indicated a significant difference before and after training (χ2 = 167, p < 0.05).

      Discussion

      In this study, customized training was found to improve knowledge, attitudes, and practices on hygienic milking and quality milk production of women dairy farmers in the central highlands of Ethiopia. Tola et al. (2016) published a research article that described women dairy farmers as primarily responsible for milk production, and Garsow et al. (2022) pointed out that they are exposed to food safety problems. Improving food safety knowledge at the farm level might not only achieve clean milk production but also play a vital role in improving the wellness and health of the family (Lindahl et al., 2018; Ahuja et al., 2019; Amenu et al., 2020; De Vries et al., 2020; Ledo et al., 2021). This study paid particular attention to developing content that was relevant to these specific farmers using targeted, simple messages and culturally relevant graphics, for example ones that showed Ethiopian women’s hands and typical milking equipment found in Ethiopian milk shades. The daily agenda was set to allow the women to attend to their family and farm responsibilities and still complete the training.

      Food safety training targeted at women could contribute to multiple positive outcomes and socioeconomic impacts (Alonso et al., 2018). The incorporation of engaging practical sessions like hand washing with Glo-Germ ™ helped reinforce concepts and provided additional opportunities for learning, particularly for adult learners that prefer to “do” rather than “read” or “watch.” The effectiveness of the training materials and approach was supported by the increase in KAPs assessment scores from pre-training to post-training for all study sites. Improving knowledge, attitudes, and practices among women farmers could have positive impacts on animal health, dairy productivity, and connecting the food to the nutrition of households and communities (Jadav et al., 2014; Stewart et al., 2015; Lenjiso et al., 2015; Amenu et al., 2019).

      Comparisons of the training outcomes and evaluation results of milk shades were found counterintuitive, which revealed the complexity of food safety interventions. We observed substandard dairy infrastructure resulting in a lack of a well-organized dairy houses and milking areas, which affected the use of hygienic practices for cleaning dairy equipment and selecting clean areas for milking. The basic requirements of dairy farming and hygienic practices emerged as critical barriers to improving milk quality at the production level.

      Personal hygiene problems might be related to limited and unclean water sources and access to personal facilities such as milking gowns, gumboots, and hair protective materials.

      Clean water sources play crucial roles in the cleaning of the dairy equipment as well as for drinking purposes of milking cows. These findings support other studies that reported that poor personal hygienic conditions and unclean water sources could be potential sources of microbiological hazards, which can affect the microbial quality of dairy products as well as animal and human health (Ransom et al., 2017; Kurniawan et al., 2018; Ledo et al., 2020. Giri et al., 2020; Jensen and Vestergaard, 2021).

      Bacteria have the ability to adhere to milk containers to form biofilm, which contain spoilage and pathogenic bacteria (Marchand et al., 2012). Staining stainless dairy equipment is important in reducing biofilm formation (Dewangan et al., 2015), and maintaining the sensory properties of the dairy products (Radu and Toma, 2024). On the question of milk containers used by the dairy farmers, this study found that almost half of the farmers used the food-grade materials for milking and handling purposes, which indicated this risk factor was less important compared to others for producing high quality milk.

      Other risk factors observed in the milk shades were related to the farm designs and layouts that indicated poor drainage, insufficient light in the dairy farm, and uncomfortable bedding materials designed for the milking cows. These practices can be a potential source of microorganisms that easily enter the food supply chain and contaminate the dairy products.

      Appropriate dairy housing should provide adequate light and natural expressions for the dairy cows, while also maintaining cleanliness of the cows and their surroundings, thereby improving the health of both animals and dairy workers (Bewley et al., 2017).

      It has been reported that unhygienic dairy environments and milking areas and poor bedding are major contributor factors to teat mastitis infections in milking cows, and, hence, farmers should use teat dipping practices to minimize the infections (Girma and Tamir, 2022). Mastitis control was observed as a major risk factor for quality milk production in this study.

      The current study provides further support of holistic approaches to the nexus of animal, human, and environmental health (Rock et al., 2009; Mwangi et al., 2016; Destoumieux-Garzón et al., 2018), through improving dairy environments and management practices (Noordhuizen and Metz, 2005), clean water for dairy cows, and safe milk productions (Fawell and Nieuwenhuijsen, 2003; Garcia et al., 2019).

      Conclusion

      This study showed that food safety training customized for women dairy farmers provides an opportunity to improve milk quality production at the farm. However, the current level of dairy farming infrastructure and farming practices poses major challenges to improving dairy product quality in the central highlands of Ethiopia. Our study has gone some way toward enhancing our understanding of a path forward to improving the dairy production system, transforming the sector from small-scale production to intermediate, clustering, or cooperatives, and encouraging commercial dairy farming for improving food system and scale up of the training.

      As part of a joint activity, the changes in microbial results and knowledge, attitude, and practices (KAPs) long time duration of the training were conducted by the TARTARE project.
