Abstract

20

The aim of this study was to evaluate the food safety knowledge, attitude and practices (KAP) of

21

food handlers from institutional food service establishments that serve hospitals, boarding senior

22

high schools and prisons in Accra, Ghana. A total of 278 food handlers (56.8% of hospital,

23

30.9% of schools and 12.3% of prison food service) participated in the cross-sectional study.

24

Data was collected by face-to-face interviews, and responses were scored to determine the level

25

of food safety KAP. Respondents who scored ≥70% of the maximum possible score were

26

adjudged to have sufficient knowledge and practices and positive attitudes. Results showed that

27

respondents’ generally had insufficient food safety knowledge and practices with means scores

28

of 20.99± 7.64 (46%) and 9.35±5.62 (52%) respectively. Attitudes towards food safety were

29

generally negative but with a comparatively higher mean score of 12.64 ±3.06 (63%). Areas of

30

most concern were 1) Lack of knowledge of sources of contamination/cross-contamination and

31

appropriate holding temperatures for food. 2) Poor practices included multiple freeze-thaw

32

cycles for frozen food and 3) Infrequent hand washing during food preparation after coughing or

33

sneezing. There is the need for continuous risk based training to educate and effect behavioral

34

changes among food handlers in order to encourage positive attitudes towards food safety and

35

consequently promote good food safety practices.

1. Introduction

41

Institutional foodservice is an important sector of the food industry. It comprises those

42

foodservice operations that function primarily as subsidiary or complementary to businesses or

43

institutions such as schools, military, nursing homes, prisons and hospitals (Williams, 2009).

44

Apart from its economic benefit, this type of catering may provide the main source of nutrition

45

for large sections of the population, including vulnerable groups such as children and patients.

46

However, the increasing scale and complexity of such catering services may lead to failures of

47

hygiene, with serious consequences for health if the strictest principles of hygiene are not

48

maintained at all stages (WHO, 1999). Foods consumed at such institutions have been identified

49

as important sources of foodborne disease outbreaks and often feature prominently in many

50

national statistics on outbreaks of foodborne illness (WHO, 1999, Sun and Ockerman, 2005;

51

Soon et al., 2011).

52

Similarly, foodborne illness outbreaks in institutional catering in Ghana have received public

53

attention. In 2007, The Daily Graphic reported food poisoning in a Ghana School Feeding

54

Program beneficiary school located in the Ga East District. Similarly, over one hundred students

55

of the Archbishop Porter Girls Senior High School in Takoradi were hospitalized over suspected

56

food poisoning which resulted in a temporary halt of academic activities in 2010 (Koomson,

57

2010). The Daily Guide (2012) newspaper also reported an incidence of food poisoning in

58

another Ghana School Feeding Program beneficiary school located in the Asunafo North

59

Municipal Assembly. In yet another incident, over 40 students from Adonten Senior High School

60

were hospitalized over suspected food poisoning (Citifm, 2013). In all these cases, the causative

61

agents were not identified due to lack of systemic surveillance system. In Ghana, the Food and

62

Drugs Authority (FDA), is the main institution responsible for ensuring that food produced for

consumption is wholesome. It works in tandem with districts assemblies through the Public

64

Health Units and Environmental Health Departments to ensure that the Public Health Act 2013 is

65

adhered to. However, District Assembly by-laws on food safety apply to only street food

66

operators. Institutional food service operators, on the other hand, are not closely monitored as

67

necessary to prevent food safety malpractices. The Ghana Food and Drugs Authority recounted

68

that 77% of all traceable foodborne diseases reported in Ghana result from improper handling of

69

food in foodservice establishments (GNA, 2013).

70

Rennie (1995) suggested that food safety knowledge influences on food safety attitudes and

71

could lead to changes in behaviors. Such information is important in designing training modules

72

and targeted mitigation strategies to advance food safety for food handlers. However, food safety

73

knowledge, attitudes and practices in institutional catering facilities in Ghana have not been

74

reported, although this sector has direct linkage to increased morbidity. Information on food

75

safety knowledge attitudes and practices of institutional foodservice has been identified as an

76

important gap in food safety research in Ghana (Ababio and Lovatt, 2015). This study will

77

bridge the knowledge gap and would highlight areas that need critical attention. The purpose of

78

this research is to evaluate the food safety knowledge, attitudes and practices of institutional

79

catering establishments in the Accra Metropolis and generate baseline data for evidence-based

80

improvements which will enable institutional foodservice operators to develop, implement and

81

maintain effective food safety management systems.

handlers on food safety. Institutions used for this study were hospitals, prisons and boarding

87

senior high schools (SHS). These institutions were selected based on the large numbers of clients

88

they serve on a regular basis, some of whom belong to vulnerable groups. A proportional random

89

stratified technique was used to randomly select participants with each type of institution

90

constituting a stratum. These were made up of 60.0% hospitals, 30.0% schools and 10.0%

91

prisons selected from the Accra Metropolitan Assembly (AMA) database of hospitals, SHS with

92

boarding facilities and prisons in Accra. A convenient sample size of 16 was selected which

93

corresponded to 53.3% of the total number of institutional catering establishments in Accra

94

metropolis. The proportionate stratifications were calculated and the following subsamples were

95

obtained: 9 hospital catering services, 5 school catering services and 2 prison catering services. A

96

simple random sampling was used to select the institutions of each subsample.

86

A semi-structured questionnaire was prepared based on validated questionnaires used in similar

101

studies in other countries (Bas et al., 2005; Buccheri et al., 2007; Tokuc et al., 2009; Buccheri et

102

al., 2010). The questions were categorized into four sections: demographic characteristics (age,

103

sex, religion, marital status, level of education and institution of work) and length of employment

104

in current institution and in catering profession, knowledge on food safety, attitudes towards

105

food safety, and measures used in the prevention of foodborne diseases.

106

Each correct answer in the knowledge, attitude and practice section of the questionnaire was

107

scored 2 points. Incorrect or “don’t know” responses were scored zero points. For the section on

108

practices, only the “yes” response was scored 2 points. “No”, “occasionally” and “often” were

scored zero points. Knowledge and practices were categorized as “insufficient” when the total

110

score was less than 70% of the maximum possible score for those sections. The respondents were

111

categorized as having “sufficient” knowledge or practices if their total score was greater than or

112

equal to 70% of the maximum possible score. Attitudes were classified as “negative” if the total

113

score was less than 70% of the maximum possible score, and “positive” if it was ≥ 70%. This

114

scoring system was adapted from a similar study by Sani and Siow, (2014). A stringent cut-off

115

score for classification was however used in this study because the selected institutions offer

116

food catering services to large populations including vulnerable groups such as sick people,

117

school children and prisoners.

2.2.2 Pilot test

120

The questionnaire and the interview procedures were pre-tested in a selected institutional

121

catering establishment outside the research area, to confirm question clarity, identify response

122

options and estimate likely interview duration. The questionnaire was then revised on the basis

123

of the pre-test results. The revised version was used for the data collection. Ethical approval for

124

the study was obtained from the Institutional Review Board of the Noguchi Memorial Institute

125

144

attitudes and practices scores were obtained using descriptive statistics. Predictors of knowledge,

145

attitudes, and practices were examined by binary logistic regression analyses. Independent

146

variables included age, gender, religion, marital status, level of education and length of service in

147

the employment/institution. Spearman’s correlation coefficient was also used to test the

3. Results and Discussion

151

3.1 Socio-demographic profile of food handlers

152

In all, 278 food handlers participated in the study. A little over half (56.8%) worked in hospital

153

foodservice establishments, 30.9% from school foodservice, and 12.3% from prison foodservice.

154

The socio-demographic characteristics of the food handlers are presented in Figure 3.1.1.The 7

ACCEPTED MANUSCRIPT

socio-demographic characteristics of the respondents did not significantly differ between the

156

three institutional categories. The age range of the participants was from 25 to 62 years; 75.9%

157

were females. Similar studies have reported a higher proportion of females to males in catering

158

establishments (Buccheri et al., 2007; Buccheri et al., 2010; Ackah et al., 2011). The dominance

159

of females in the catering business could be attributed to their traditional food preparation

160

responsibilities at the home (Ackah et al., 2011). The majority of the respondents could be

161

classified as experienced food handlers as over 60% had more than 5 years’ experience in food

162

service. Though experience ranked high among respondents, level of education was rather

163

moderate. The most frequently reported educational level was senior high school (SHS) while

164

11% of respondents had no formal education. This was noteworthy because workers who have

165

no formal education and incomplete basic school education are less likely to properly follow

166

procedures on safe handling of food (Clayton et al., 2002).

Table 3.1.1 shows results of a series of binary logistic regression models which were used to

169

determine if any of the socio-demographic characteristics of the respondents could reliably

170

predict the outcome of sufficient knowledge and practices as well as positive attitudes with

171

regards to food safety. None of the independents variables tested in this study had any predictive

172

power on the outcome of sufficient food safety knowledge and practices and on positive

173

attitudes. Characteristics such as formal education, age, gender, religion or marital status would

174

therefore not be suitable bases to assess whether institutional food handlers in the study area

175

would have knowledge, attitudes and practices that would impact food safety.

3.2 Food safety knowledge

177

The food handlers generally had insufficient food safety knowledge levels with a mean score of

178

20.99± 7.64, representing only 46% of the maximum possible score. Table 3.2.1 displays the

179

food safety knowledge level of the food handlers.

180

Virtually all the respondents had heard of foodborne illness. The predominant sources of

181

information about foodborne illness were reported to be radio (47.7%) and television (29.5%).

182

Diarrhoea was the most frequently (65.7%) identified symptom of foodborne illness. Less than

183

2% of the participants included paralysis, dizziness and fatigue as symptoms of foodborne

184

illnesses. This was expected since the most reported manifestation of foodborne disease in the

185

media is diarrhoea. Almost all (98.2%) of the food handlers knew about germs and it was also

186

the most frequently cited cause of foodborne illness. Less than 10% of the food handlers

187

recognized food allergens, insecticides and extraneous matter in food as possible causes of

188

foodborne illness. This is troubling because, they may neglect to take the necessary steps to

189

control these hazards in the food they handle. More than three quarters of the respondents

190

however knew about food safety practices such as keeping fingernails unpolished, short and

191

clean; use of hair caps and masks and also about adequate personnel protective materials.

192

Water used for cooking food was the most recognized route of microbial food contamination.

193

More than half of the respondents however failed to recognize that disease causing

194

microorganisms could get into food through raw materials/ingredients, working surfaces and

195

cooking utensils. Knowledge of raw materials and food contact surfaces as possible routes of

196

food contamination is important to prevent cross-contamination or recontamination of food

197

during handling, preparation and storage. Cross-contamination of foods via materials/ingredients,

AC C

utensils and work surfaces is well established as a major risk factor in the catering industry

199

(Harrison et al., 2003; Redmond and Griffith, 2004; Reji and den Aantrekker, 2004).

200

3.3 Food safety attitude

201

Table 3.3.1 summarizes the findings on food safety attitudes of food handlers. The results

202

showed an overall negative attitude towards food safety, with a mean score of 12.64 ±3.06

203

(63%). Closer inspection however reveals positive attitudes particularly towards safe storage

204

practices; correct handling of food, toxic chemicals, and good personnel hygiene practices.

205

Almost all the respondents (93.9%) had a positive attitude towards proper storage of toxic

206

chemicals in food establishments, policy on employees suffering from foodborne illness or other

207

contagious illness, and use of antibacterial soap or hand sanitizers in hand washing. However, a

208

negative attitude was observed for the appropriate temperature for storage of food, especially

209

regarding attitudes towards refreezing of defrosted foods. Similar results were obtained from

210

previous studies (Angelillo et al., 2001; Askarian et al., 2004; Buccheri et al., 2007). Substantial

211

numbers of food handlers were not sure about refreezing of defrosted foods, suggesting

212

insufficient knowledge on that subject. Failure to perceive such an important food handling risk

213

may be an impediment to successful implementation of food safety control measures in

214

institutional food service. Multiple freeze-thaw cycles have been reported to allow microbes,

215

especially pathogens on the surface of thawing foods to multiply to levels that can cause food

216

spoilage or illness (Schmidt and Rodrick, 2003). Hence, it is recommended that defrosted foods

217

should not be refrozen.

ACCEPTED MANUSCRIPT

Additionally, only 13.7% of respondents said they intended to check the thermometer settings of

221

refrigerators and freezers at regular intervals. Food handlers may not feel the need to carry out

222

this practice if they cannot recognize unsafe temperatures. Other authors have reported a general

223

lack of knowledge of food handlers on correct refrigeration temperatures (Angelillo et al., 2001;

224

Askarian et al., 2004; Buccheri et al., 2007; Tokuc et al., 2009). The results of this study also

225

revealed that 29.5% were of the impression that refrigeration could kill pathogens in foods. This

226

is an attitude that could have serious implications for food safety, given the widespread use of

227

refrigeration facilities in catering services.

228

3.4 Food safety practices

229

The importance of food safety practices in the prevention of food borne illnesses cannot be over-

230

emphasized. Table 3.4.1 summarizes the responses of food handlers concerning their food safety

231

practices. It was found that the self-reported practices of the food handlers were generally

232

insufficient with a mean score of 9.35±5.62 (52%).

TE D

233

220

Hand washing is a critical food safety practice that was fortunately well observed by

235

respondents. It was also encouraging to note that, majority (92%) of the respondents reported

236

washing their hands with antibacterial soap after visiting the toilet. Washing of food contact

237

surfaces such as chopping boards, tables and knives with antibacterial soap before food

238

preparation was also a very frequent practice among the respondents. The importance of regular

239

hand washing with antibacterial soap was substantiated in a study by Toshima et al. (2001), who

240

found that anti-bacterial soap had greater efficacy (>95%) in reducing total coliform counts on

241

hands even with shorter washing times.

AC C

EP

234

11

ACCEPTED MANUSCRIPT

The use of disposable tissue when coughing or sneezing, followed immediately by hand washing

243

was however not a common practice among food handlers. A number of studies have implicated

244

the hands of food handlers as a significant mode of pathogen transmission in foodservice

245

establishments (Taylor, 2000; Montville et al., 2001). Food handling personnel must therefore

246

carefully wash their hands when they arrive at the workplace as well as before and after they

247

handle the food; every time the handling is interrupted; every time they touch any potentially

248

contaminated objects; after using the bathroom and whenever else it may be found necessary.

249

According to Todd et al. (2009), hand hygiene is considered more critical in the control of

250

pathogens than cleaning and disinfection of environmental surfaces. Improved personal hygiene

251

and scrupulous hand-washing would lead to the basic control of faeces-to-hand-to-mouth spread

252

of potentially pathogenic transient microorganisms (Shojaei et al., 2006).

M AN U

SC

RI PT

242

253

Only 36.0% reported that they use separate utensils to prepare raw and ready-to-eat food.

255

Checking the shelf life of food products and the integrity of food packages were less frequently

256

reported. Less than half of the respondents always observed this step during food preparation.

257

Figure 3.4.1 shows the incorrect responses given by food handlers on questions about their food

258

safety practices.

259

Improper thawing of frozen food at room temperature appeared to be widespread among

260

respondents. It can be observed from Figure 3.4.1 that, over 50% of respondents always (100%

261

of the time) thawed their food at room temperature. Meanwhile, a significant number of

262

respondents reported that they only thawed food at room temperature occasionally (40% of the

263

time). This may be indicative of the fact that, they may have been aware of the risks associated

264

with this practice but may have neglected to carry it out because of certain constraints. A similar

AC C

EP

TE D

254

12

ACCEPTED MANUSCRIPT

265

argument could be made for practices such as checking the integrity of packaging as well as

266

checking the shelf life of foods prior to their use.

RI PT

267

1.5 Association among the food safety knowledge, attitudes and practices of food handlers

269

There were significant positive correlations between knowledge and attitudes, knowledge and

270

practices and, attitudes and practices. This suggests that food safety knowledge of respondents

271

will most likely influence their attitudes and practices regarding the safe handling of foods. The

272

results also insinuate that attitudes towards food safety could adequately predict the actual food

273

safety practices of food handlers. These findings have been summarized in Table 3.5.1.

274

The poor food safety knowledge observed among food handlers in this study would naturally

275

suggest an educational intervention. The negative attitudes also realized in this study would

276

however advocate motivation and training; not just education. This is because negative attitudes

277

toward food safety suggest the need for behavioral changes in addition to food safety training.

278

Michaels (2002) recommended that, although a certain amount of education is necessary, the

279

approach must be multidisciplinary, targeting institutional or organizational change. Systems

280

such as equipment and logistics supply, monitoring as well as constant reminders such as posters

281

and leaflets, need to be put in place to encourage good behaviors and discourage bad ones. The

282

training must be risk-based with consequences of failure clearly expressed and understood at all

283

levels.

4. Conclusion

287

This study investigated the food safety knowledge, attitudes and practices of food handlers in

288

institutional catering facilities in Ghana. The results highlighted significant gaps in knowledge,

289

attitudes and practices of safe food handling. Areas of most concern were storage of food in the

290

danger zone, practices that could lead to cross-contamination of food, multiple freeze thaw

291

cycles, and thawing of frozen food at room temperature. These gaps could be resolved with risk-

292

based training of food handlers in institutional catering facilities using appropriate training aids

293

to encourage understanding and appreciation of the applications of food safety principles in their

294

day-to-day operations. Training interventions should cover appropriate storage temperatures,

295

thawing of frozen foods, and hand washing after coughing and sneezing during food preparation.

296

Habits must be changed to obtain a sustained improvement in food safety practices and this can

297

only be accomplished through continuous and gradual training, monitoring and resource

298

improvement. Techniques employed in this process must also be tailored to accommodate the

299

low education levels of the food handlers.
