ABSTRACT
Meat handlers are vectors of pathogens in slaughterhouses and can play a major role in the microbiological contamination of meat. The level of knowledge of meat handlers in slaughterhouses is a critical factor in food safety. Good hygienic practices in the slaughterhouse are required to reduce the risk of microbiological contamination while handling meat. This study evaluated workers' knowledge, attitudes, and practices in four municipal slaughterhouses in Morocco. A total of 267 employees were evaluated using a structured survey. The results showed that workers had acceptable knowledge and practices, and their attitudes were very satisfactory, averaging 52.87%, 50.9%, and 63.07%, respectively. A positive correlation between the workers' level of knowledge and education was found in all studied slaughterhouses. Similarly, the results indicated a positive correlation between knowledge and attitudes at Meknes and Kenitra slaughterhouses. The impact of the studied sociodemographic characteristics may vary from one slaughterhouse to another. In conclusion, the study suggested that although the knowledge, attitudes, and level of practice of food handlers were very satisfactory, some aspects related to the control of the health status of the handlers and personal protective equipment had to be underlined. Ongoing food safety training should become mandatory to enhance food safety in the slaughterhouses of study locations.

INTRODUCTION
The increasing number of epidemic outbreaks of food poisoning and food crisis worldwide forces authorities to apply the best hygiene and quality practices (Ba§ et al., 2006). According to the world health Organization, Global estimates on foodborne diseases indicate the annual infection of more than 600 million people by consuming contaminated food with bacteria, viruses, or parasites, and 420000 deaths (WHO, 2017). Poor hygiene and sanitation conditions in meat processing establishments, such as slaughterhouses, contribute significantly to the high incidence of community-acquired foodborne diseases, which are frequent and sometimes severe (Egan et al., 2007; Lues and Van Tonder, 2007; WHO, 2006).
In Morocco, more than 90% of collective food poisoning is due to bacteria, of which meat products constitute 11% (Belomaria et al., 2007). In 2016, the Moroccan Poison Control Center (CAPM) recorded 2723 cases of food poisoning, 53% of which were cases of collective food poisoning (Ghailani et al., 2020). Butchers working in slaughterhouses are the main vectors for meat contamination (Todd et al., 2010; Jianu and Chi§, 2012; Matchawe et al., 2019). Investigations into foodborne disease outbreaks have shown that poor personal hygiene plays a major role in the passive transmission of pathogens, such as Noroviruses, Salmonella species, Staphylococcus aureus, and Shigella species. These pathogens are often present in handlers' wounds, mouth, skin, and hair. Furthermore, the unwashed hands of workers can also tra nsmit pathogens, particularly fecal pathogens (Sharif et al., 2013; Lambrechts et al., 2014).
Morocco has 180 municipal slaughterhouses, 3 approved private slaughterhouses, and 223 (out of 702) uncontrolled rural slaughterhouses (Annual report of the court of auditors of Morocco, 2018). Most of these slaughterhouses do not fulfill the hygienic requirements recommended by the National Office for Sanitary Safety of Food Products (ONSSA), such as a lack of hygiene training for working staff (Annual report of the court of auditors of Morocco, 2018). A knowledge, attitude, and practice (KAP) survey is a structured, standardized questionnaire used for a particular population to collect information about what is known, believed, and done on a specific topic (WHO, 2008). This type of investigation serves as an educational diagnosis of populations (Salih et al., 2019). Surveys on KAP have become a widely used means of research worldwide for public health studies to propose reflections on the training of food handlers, given their responsibility for food safety and consumer health (Ahmed et al., 2020). Several studies have been conducted to evaluate these processes in food safety in international slaughterhouses (Annor and Baiden, 2011; Abdul-Mutalib et al., 2012; Soares et al., 2012).
109
The current study is a complement to previous research published by the Laboratory of Microbiology and Molecular Biology, Mohammed V University, Rabat, Morocco, providing information on the level of knowledge, attitudes, and practices of workers, as well as on the microbiological situation of the slaughter areas of the municipal slaughterhouses of Marrakech city located in southern Morocco (Bahir et al., 2022). This study aimed to assess the knowledge, attitudes, and practices of food handlers in four Moroccan municipal slaughterhouses in Rabat, Salé, Kenitra, and Meknes, situated in Morocco.
MATERIALS AND METHODS
Ethical approval
All the information in this study was based on the recommendations of the Faculty of Sciences, Mohammed V University, Rabat, Morocco. Authorizations were requested from the administration of each slaughterhouse, which granted permission to carry out the surveys. The manipulators involved in the current study were reported anonymously.
Study area
Present work concerned four municipal slaughterhouses located in the northwest of Morocco (Rabat, Sale, Kenitra, and Meknes). In Morocco, the sanitary inspection of municipal slaughterhouses is carried out by the veterinarians of ONSSA, while the administrative management is under the supervision of the Ministry of Interior. The choice of the studied slaughterhouses was based on the accessibility to their geolocation. The authorization of the responsible authorities was obtained for the realization of this survey. For this purpose, the interviewed participants included 267 randomly selected male employees working in cattle or sheep slaughterhouses, cutting rooms, or the carcass transportation sector. The number of interviewed participants in each slaughterhouse varied depending on the size of the abattoirs and their willingness to participate in the surveys. Meat handlers were voluntarily and randomly selected. A structured questionnaire with different sections was administered to all participants. The questions were explained and read aloud to the participants, who were given sufficient time to answer each question. No one was forced to participate in the survey.
Survey
The survey was conducted between January and April 2021. Based on previous research, a structured four-part study was developed to assess the sociodemographic characteristics, knowledge, attitudes, and slaughter practices of food handlers (Angelillo et al., 2001). Information on the sociodemographic characteristics of the handlers was mainly related to their work area in the slaughterhouse, age, level of education, work experience, training in meat hygiene, and health status. The information on workers' knowledge of food safety included 10 questions related to microbiological risks of carcass contamination, the importance of refrigeration and personal hygiene, and risks related to foodborne illness, to which participants were given the option of answering "Agree" or "Disagree". Following the same, respondents' attitudes toward food safety were also assessed by 10 questions addressing their personal hygiene and the cleaning of surfaces used during the slaughter process, as well as the standard cleaning of the used equipment. The participants could be scored 0-10 for the knowledge and attitude sections. The obtained results have been converted to 100%. Scores between 40% and 70% were considered acceptable, while scores more than 70% were considered excellent. The slaughter practices section included 18 questions on topics related to hygiene and the wearing of personal protective equipment during work. Participants were asked to answer "yes" or "no". A score was assigned to each correct answer and converted to a percentage. An average was calculated for each section to get a global idea of the handlers' knowledge, attitudes, and practices.
Statistical analysis
The statistical analysis was performed using version 2021 of XLSTAT Life Sciences, UK. The relationship between the sociodemographic profile of the carcass handlers and their KAP levels was determined using the chi-squared test. Differences in the mean of participants within each group studied were analyzed using a one-way ANOVA integrated post hoc test to show that particular differences between pairs of means are significant. Statistical significance for all tests was set at p < 0.05 using Ducan Test.
RESULTS
Sociodemographic characteristics of respondents
Tables 1 to 4 summarize the results concerning sociodemographic characteristics. Information on the sociodemographic characteristics of the carcass handlers included their work area in the slaughterhouse, age, education level, work experience, and hygiene training. The findings indicated that 56% (n = 45), 65% (n = 26), and 66% (n = 56) of participants were practicing cattle slaughter in Rabat, Salé, and Meknes, respectively. However, almost all
110
respondents (93.55%, n = 58) were sheep slaughters in Kenitra. A minority in Rabat worked in trip cleaning (6.25%) or transporting the carcasses (17.25%) to cold storage (Table 1).
The majority of handlers aged between 18 and 40 years, according to their recruitment, physical strength, and performance during the different slaughter operations. A few workers were under 18 years of age in Rabat (4%) and Kenitra (4.84%, Table 2). College and primary levels of education were 26.25% and 38.5% in Rabat, 60% and 20% in Sale, 30.59% and 32.94% in Meknes, and 35.48% and 27.42% in Kenitra, respectively (Table 3). The majority of handlers had good professional experience and worked for more than 20 years, compromising 41.25% in Rabat, 50% in Sale, 31.76% in Meknes, and 47.77% in Kenitra slaughterhouse (Table 4).

Handler training in meat hygiene and handling
111
In the four slaughterhouses, the majority of workers had no training in hygiene and meat handling. Only a minority of workers received this type of training, including 12.5% in Rabat, 20% in Sale and 7.06% in Meknes, and 0% in Kenitra (Table 5). With regard to the number of training sessions, the majority were rarely trained (1 to 4 times per year). Thus, of the 10 workers who received training, 70% (n = 7) rarely received training when offered by private companies in the Rabat slaughterhouse, and 30% (n = 3) received training 1 to 4 times per year. In Salé slaughterhouse, workers (n = 8) rarely received training. For Meknes, only 5% (n = 4) of the workers had training once a year 2.5% (n = 2) barely received any hygiene training (Table 6). On the other hand, 100% (n = 24) of the workers in all slaughterhouses who received training considered training as effective (Table 7), and intended to conduct such training in the near future (Table 8).

The medical situation of the workers
The majority of handlers did not have a health certificate. According to the current regulation in Morocco, there should be medical files for all meat handlers, and the files must be updated annually. These files must be made available to the veterinary inspector. This document indicates the medical aptitude to perform slaughter activities. However, it has been observed that staff are rarely provided with medical certificates, which are not updated in Rabat, Sale, Meknes, and Kenitra at rates of 93.75% (n = 75), 82.5% (n = 33), 78.82% (n = 67), and 88.71% (n = 55), respectively (Table 9). On the other hand, 41.18% of the workers had a medical check-up before being hired in the slaughterhouse of Meknes (Table 10), and a very small number of workers did this operation before in Rabat, Sale, and in Kenitra slaughterhouses. Only 20% of the workers in the Kenitra slaughterhouse continued these check-ups (Table 11). The interval of the sanitary control of workers varied from one slaughterhouse to another. In Rabat, the majority of workers (41.25%, n =
112
33) checked their health status every 3 months, and 20% (n = 10) and 17.5% (n = 14) of them reported having consulted a doctor between 6 months to a year, respectively. In Meknes and Kenitra, the majority of handlers declared having checked their health status between 6 months and a year. In the Salé slaughterhouse, 50% (n = 20) of the workers never checked their health status (Table 13). Except for the Kenitra slaughterhouse, many workers never consulted a doctor in their life, 21.25% (n = 17), 25% (n = 10), and 16.47% (n = 14) of workers in Rabat, Salé, and Meknes, respectively (Table 13).

Handlers' hygiene knowledge
113
Generally, a good knowledge of hygiene was approached by half of the workers (54.16%, 55.8%, 48.7%, and 52.9% in the slaughterhouses of Rabat, Sale, Meknes, and Kenitra, respectively). Most workers were aware of the microbiological risks, the importance of good hygiene practices in the workplace, and the impact of shelf life on meat contamination. In the Kenitra slaughterhouse, only 37% (n = 23) of the workers knew that unhygienic handling could be a source of meat contamination. In the slaughterhouses of Rabat and Kenitra, 59% (n = 47) and 55% (n = 34) of workers knew that refrigeration delays contamination, respectively, while this was not the case for workers in Salé (25%) and the slaughterhouse in Meknes (18.18%). In the Rabat and Meknes slaughterhouses, 51.3% (n = 41) and 56.5% (n = 48) of the workers were aware that microbial contamination of meat could cause serious illnesses leading to hospitalization and sometimes death, respectively. The level of knowledge of handlers about the risk of microbial contamination by a person suffering from diarrhea was generally very low at 46% (n = 37), 32.5% (n = 13), 35.3% (n = 30), and 44% (n = 27), in Rabat, Sale, Meknes, and Kenitra, respectively (Table 14).

Generally, the various handler statements regarding attitudes, hygiene, and meat handling were satisfactory. The mean values of correct answers were significantly positive in each slaughterhouse at 67.3% in Rabat, 55.1% in Salé, 68.5% in Meknes, and 61.44% in Kenitra. The majority of handlers in Rabat slaughterhouse (82.5%) agreed with the obligation of continuous monitoring using medical tests before hiring. On the other hand, handlers at Salé (85%) and Kenitra slaughterhouse (75.81%) considered it unnecessary. The majority of workers agreed with the continuous monitoring of medical tests. Attitudes in relation to hand washing and the importance of disinfecting premises were very satisfactory. The attitudes of the majority of workers concerning wearing personal protective equipment were weak. In Rabat and Salé, 88.75% (n = 71) and 67.5% (n = 27) of slaughterers considered using an apron during slaughtering operations as unnecessary, respectively. In the same direction, 80% (n = 64), 90% (n = 40), 74.11% (n = 22), and 88.71% of the handlers in Rabat, Salé, Meknes, and Kenitra slaughterhouses considered the handling of carcasses with lesions on the hands did not constitute a risk of contamination, respectively. In the Salé slaughterhouse, 67.74% (n = 20) of handlers considered that the deposit of meats on the floor did not contain any risk of contamination (Table 15).
Hygiene practices
Regarding slaughter practices of handlers, the average of correct responses obtained was between 47.9% and 54.12%. Most handlers reported that they washed their hands before the slaughter. Their responses were at the rates of 77.5% (n = 62) in Rabat, 80% (n = 32) in Salé, 78.8% (n = 67) in Meknes, and 100% (n = 62) in Kenitra, but they did not generally use a disinfectant except for one employee in Kenitra. Similarly, most handlers washed their hands after using the toilet but did not use sanitizer. In the 4 slaughterhouses, the majority of workers declared that they handled carcasses with lesions on their hands at response rates of 80% (n = 64) in Rabat, 90% (n = 36) in Salé, 74.1% (n = 63) in Meknes and 88.7% (n = 55) in Kenitra. More than half of the handlers in Rabat and Meknes slaughterhouses announced that they handled carcasses with diarrheal syndrome (57.5% and 56.5%). On the other hand, the majority of workers declared this fact in Salé and Kenitra, 85% (n = 34) and 61.3% (n = 38), respectively. As for the cleanliness of the handlers, the majority cut their nails and used boots, but most of them did not use gloves and aprons during slaughter operations. The majority of the handlers in Salé slaughterhouse (75%) announced that meat did not affect the working environment, unlike in Rabat, Meknes, and Kenitra slaughterhouses, 62.5% (n = 50), 89.4% (n = 76) and 69.4% (n = 43), respectively. Most slaughterers followed good practices to clean the slaughter area and equipment before and after the slaughter process (Table 16).

Correlation between respondents' attitude level, knowledge, and sociodemographic characteristics in the municipal slaughterhouses of Rabat, Salé, Meknes, and Kenitra in Morocco
Rabat slaughterhouse
The relationship between attitude level and sociodemographic characteristics in Rabat slaughterhouse showed a strong significant correlation (X2 = 5.96; p < 0.05) between slaughter area and attitude level. An excellent attitude is related to the cattle slaughter zone. The odds ratio presented a value of 0.25, indicating a negative attitude effect for the cleaning trips and transporting carcasses. The chi-square, prevalence, and odds-ratio indices indicated no relationship between age and attitude level. There was also a significant correlation between education and attitude level (low education is related to an excellent attitude). This can be explained by the correlation between attitude level and work experience (Odds ratio = 4.20, p > 0,05, Table 21).
Sale slaughterhouse
In Sale slaughterhouse, the results showed a correlation between age and attitude level (the youngest manipulators had a positive attitude, compared to the oldest manipulators) with X2 = 3.30. There was no correlation between knowledge and attitude level (X2 = 0, p > 0.05).
Meknes slaughterhouse
There was a correlation between knowledge and attitude in Meknes with X2 = 2.63. The statistical indices showed almost no correlation between age and attitude level (Table 23).
Kenitra slaughterhouse
In Kenitra slaughterhouse, knowledge correlated with attitude (X2= 3.21). The statistical indices indicated almost no correlation between attitude level and the other variables (Table 24).

Correlation between hygiene and meat handling practices and sociodemographic characteristics of handlers in Rabat, Sale, Meknes, and Kenitra slaughterhouses
Rabat slaughterhouse
The results regarding the correlation between sociodemographic factors and slaughter practices showed a highly significant correlation between practice level and slaughter area (X2 =11.55; p < 0,05). Prevalence and Odds-ratio confirmed this correlation, showing a negative effect between the level of practices and the washing of the entrails and the transport area with 0.16 and 0.31, respectively. The results also revealed a positive correlation between the level of practice and the education level of handlers (X2 = 3.17). Unacceptable slaughter practices were associated with low education levels (Table 25).
Sale slaughterhouse
The results in the Sale slaughterhouse showed a positive correlation between slaughter practices and handlers' level of education (X2 = 1.78, prevalence = 0.55, and Odds-Ratio = 0.39). The results of the slaughter area, age, and work experience showed no significant relationship between these factors and the level of handlers' practices.
Meknes slaughterhouse
In the slaughterhouse of Meknes, the results indicated that an acceptable level of slaughter practices was related to a young age range of handlers with an X2=2.37. The other statistical indices showed almost no significant relationship between slaughter practices and other sociodemographic factors.
Kenitra slaughterhouse
In the slaughterhouse of Kenitra, the obtained results showed almost no positive correlation between slaughter practices and sociodemographic factors.

DISCUSSION
This study provided valuable information on the knowledge, attitudes, and practices of handlers regarding hygiene and meat handling in four municipal slaughterhouses in Morocco. The information collected on workers' knowledge of food safety highlighted the microbiological risks of contamination of carcasses, the importance of refrigeration and personal hygiene, and the risks related to foodborne diseases. Regarding handler attitudes, the study identified the handler's personal hygiene, cleaning of surfaces used during the slaughter process, and standard cleaning of equipment used. Considering slaughter practices, topics related to hygiene and wearing personal protective equipment during work should be focused. Several studies have reported that handlers working in meat processing factory directly impact foodborne disease outbreaks (Howes et al., 1996; Clayton et al., 2002). The results of this study showed adequate knowledge and practices, while attitudes were very satisfactory. In the four slaughterhouses, almost all respondents were aware of the microbiological contamination of carcasses and the risks associated with consuming contaminated meat. At the same time, they were not aware of the modes of disease transmission as most of them believed that working with diarrhoeal syndrome or using water from cleaning pipes during slaughter did not have any contamination risk. This is in agreement with the study by Matchawe et al. (2019), who reported that 43.1% of respondents in the slaughterhouse of Yaoundé, Cameroon, stated that disinfecting facilities were not important in reducing the risk of carcass contamination.
For meat refrigeration, 75% and 82% of respondents in the slaughterhouses of sale and Meknes did not have enough information, respectively. In Rabat and Kenitra, most respondents were also conscious of the importance of refrigeration in storing and reducing meat contamination. A study conducted in Turkey by Ba§ et al. (2006) showed that 63.1% of the respondents knew the importance of the refrigerator temperature to minimize food safety risks since temperature handling is often the critical control point in a production process.
Misunderstanding temperature can impede the implementation of any Hazard Analysis Critical Control Point (HACCP) policy (Walker et al., 2003). The results of a study conducted in Turkey by Ba§ et al. (2006) suggested that 63.1% of the surveyed individuals were aware of the importance of temperature control in minimizing food safety risks. Walker et al. (2003) highlighted that a lack of knowledge regarding temperature handling in a production process could be a major obstacle in implementing any Hazard Analysis Critical Control Point (HACCP) policy.
The results dealing with the attitudes of meat handlers were generally standard. According to Abdullah Sani and Siow (2014) and Al-Shabib et al. (2016), attitude is a critical factor that can impact the food safety behavior and practices of food handlers by reducing the incidence of foodborne illness. Respondents in the four slaughterhouses surveyed were aware of general hygiene measures, such as mandatory hand washing with disinfectant after using the toilet, disinfection of slaughter areas, as well as the prohibition of the deposit of offal on the floor. In contrast, the majority of respondents failed to answer the question correctly. Handlers believed that working with lesions on their hands does not pose a risk of carcass contamination. In contrast to the present study, Zanin et al. (2015) identified that nearly 85% of their staff were conscious of the risk of touching food with cuts on their hands or fingers. The Food and Drug Administration (FDA) (2017) reported that food handlers with illnesses or cuts and injuries on their hands had to stop work immediately and leave the workplace to prevent the transmission of foodborne illness. In Rabat and Sale, food handlers found it unnecessary to wear personal protective equipment. Similarly, respondents in Sale and Kenitra believed that health checks were not required before hiring. This is in disagreement with Ansari-Lari et al. (2010), where 93.8% of the handlers at the meat processing factory in Fars, Iran, found that wearing personal protective equipment was an indispensable act to avoid carcass contamination.
According to Zanin et al. (2017), attitude plays a critical role in slaughter practices, as there is a key link between knowledge and practice; workers with an acceptable level of knowledge are more likely to translate it into practice if they have a positive attitude. Hand washing before each manipulation and after each use of the toilet by the majority of handlers remained among the most encouraging results. Similar results have been reported in previous studies by Al-Kandari et al. (2019), showing that 99.5% of respondents washed their hands before and during food handling. Moreover, lack of hand hygiene is a very important risk factor in food poisoning, according to the Codex Alimentarius Commission (2003). In the present study, 62.5%, 25%, 90.6%, and 69.4% of respondents in Rabat, Salé, Meknes, and Kenitra, respectively, reported direct contact with bare hands with the wall, floor, and equipment during slaughter operations. A previous study by Al-Kandari et al. (2019) stated that 51.7% of the handlers used bare-hand contact with ready-to-eat foods. The lack of cleaning devices in the workplace, the absence of training and awareness programs, and the low level of education of the participants in this study may explain this.
A significant positive correlation existed between the handlers' knowledge and their education level in all studied slaughterhouses. This is consistent with the work of Ansari-Lari et al. (2010), Martins et al. (2012), and Abdul-Mutalib et al. (2012). The correlation of attitudes with sociodemographic factors varied in each slaughterhouse. A positive correlation between attitudes and knowledge was observed in Meknes and Kenitra. Similarly, there was a positive correlation between attitudes, education level, and slaughter area in Rabat.

The results of the correlation between practices and sociodemographic factors are presented in tables 15-19. A positive correlation was reported in the slaughterhouse of Rabat between the practices and the slaughter area, as well as with the education level in Meknes. A positive correlation was detected with the age of the meat handlers in Meknes. In Salé and Kenitra, the obtained results were similar to these of Matchawe et al. (2019), who reported no correlation between practices and sociodemographic factors. Effective education of workers about food safety can minimize the risk of bacteriological contamination throughout the food chain. Foodborne illness cannot be reduced without food handling procedures and knowledge of food safety practices (Salih et al., 2019). Bahir et al. (2022) showed that meat could easily be contaminated during the slaughtering process by a low level of knowledge and poor practices of handlers, as well as the high bacterial loads and some pathogenic bacteria isolated from most of the studied surfaces in slaughterhouses of Marrakech, Morocco.
CONCLUSION
This study complemented previous research compiled by the current study research team. The work constituted an inventory of the red meat slaughterhouses in Morocco to get a maximum of information on the slaughtering sector in the country. The present study indicated that training and awareness programs for handlers on health risks and hygienic handling of meat must be strengthened to improve food safety in the country. The obtained results showed that while the level of KAP is satisfactory in the four studied slaughterhouses, other hygienic aspects need to be highlighted. Also, sociodemographic factors can directly impact the handlers' knowledge, attitudes, and practices. Microbiological studies should complement the studies to link the level of awareness of handlers on good hygiene practices with the risks and the dissemination of pathogens on slaughter surfaces. The authors of the current study recommended this type of research to contribute to the understanding of the current situation of handlers in slaughterhouses in Morocco and to implement authorities to take actions to reduce the occurrence of toxic infections among consumers.
