The relationship among food safety knowledge,attitudes and self-reported HACCP practices in restaurant employees

This study investigates relationships among food safety knowledge, attitudes and hazard analysis critical control point (HACCP) practices in restaurant employees in Taiwan. The authors administered a baseline questionnaire to 542 restaurant employees to assess their food safety knowledge, attitude and HACCP practices. A total of 421 valid questionnaires were returned and used in analysis. Mean scores for each survey item were calculated and used in a structural equation model (SEM) designed to assess interrelationships between the three. Participants scored an average 84.7% correct in food safety knowledge, with highest and lowest correct scores in, respectively, the food poisoning and good hygienic practices (GHP) constructs. The highest score in the attitude section was “concern for food safety” followed by “self-improvement.” With the exception of the food poisoning construct, this study found correlations among knowledge, attitude, and HACCP practices, with attitude mediating the relationship between knowledge and HACCP practices. The implications of these findings are discussed.     

HACCP in practice

The hazard analysis critical control point system (HACCP) has been evolving in the food industry since it was first deliberated by the First National Food Protection Conference. Small- and medium-sized enterprises (SMEs) are companies with fewer than 500 full-time employees. This article addresses the implementation of HACCP in SMEs, highlighting some of the problems. The problems can be arranged in four groups: insufficient technical resources, concentration of functions, time and financial power. It is the conclusion of this article however, that there are no barriers to the application of HACCP in all food production operations.     

Implementation of Food Safety Management Systems in small food businesses in Cyprus

EU legislation requires that food businesses in all member states must implement a Food Safety Management System based on HACCP principles. Although manufacturers have used this system successfully for many years it has been less common in small and medium sized enterprises (SMEs), especially those in the food service sector. There are considered to be a number of barriers which small businesses find particularly difficult to overcome. This study assesses the impact of various Food Safety Management Systems in 50 small businesses in Cyprus. It compares food hygiene before, during, and after implementation of the food management systems, assesses the attitude of the Food Business Operators and the hygiene knowledge of the staff. Results show that the maximum improvement came when implementing the pre-requisite programmes and a bespoke HACCP plan but that a deterioration in standards could be identified when using more complex systems such as the CYS 244 standard or ISO 22000. Food Business Operator attitude started positively but became more negative as the complexity of the Food Safety Management System increased.     

Survey on typology,PRPs and HACCP plan in dry fermented sausage sector of Northern Italy

One hundred and fifty four dry fermented sausage small and medium-sized enterprises (SMEs) were visited in Northern Italy, to collect information on building and facilities, production technology and marketing organization. Five businesses, out of 154, were then selected with the aim of analysing their prerequisite programmes (PRPs) and the level of hazard analysis and critical control point (HACCP) system implementation. The results of this survey acknowledge the importance of small enterprises in the dry fermented sausage production sector. This study shows that fully compliance with PRPs and HACCP is far from complete, especially in micro-sized businesses, in spite of derogations for small establishments provided by Italian and European rules. In order to help SMEs to comply with food safety objectives, collaboration with Local Health Unit officers always proves positive for the businesses because they can inform and support enterprises, particularly small food premises.     

Reducing the burden of HACCP on SMEs

Despite the acknowledged contribution of Small and Medium Enterprises (SMEs) to the food industry there is increasing evidence that Hazard Analysis Critical Control Point (HACCP) implementation is limited in this sector, with the burden of implementation perceived as potentially insurmountable. Using an action research methodology, this in-depth, government funded research project took the form of a two stage, 18 month investigation into methods of reducing burdens of HACCP on SMEs. Stage one indicted that SMEs see HACCP as a difficult, complex set of activities requiring great amounts of time effort and with few, if any, perceived benefits. In stage two, however, with the help of research tools developed, a number of SMEs completed HACCP and many made good progress on a tight timescale. This research thus concludes that SMEs can achieve HACCP if they are provided with sufficient guidance and support in a context of general consensus of HACCP terminology and requirements. Recommendations are made, many of which have been subsequently adopted by the UK Food Standards Agency.     

Food safety knowledge and attitudes: culture and environment impact on hawkers in Malaysia.: Knowledge and attitudes are key attributes of concern in hawker foodhandling practices and outbreaks of food poisoning and their prevention

This study determined the impact of culture and environment on knowledge and attitudes of hawkers towards food safety, foodborne illnesses and their prevention. One hundred hawkers in Kuala Lumpur (KL) were interviewed, using a structured interview schedule. Environment did not effect hawkers’ knowledge and attitudes. Education influenced knowledge and attitudes scores of the interviewees. Differences in knowledge of the ethnic groups were in cross-contamination, equipment, utensils and premises, personal hygiene, hazard analysis critical control point (HACCP) and food regulations and control. Malay and Indian hawkers had better educational background, hence better knowledge and attitude scores than Chinese. The findings highlight the importance of education to bridge cultural gaps in food safety knowledge and attitudes. A strong relationship exists between the knowledge and attitudes of hawkers.     

HACCP – The difficulty with Hazard Analysis

HACCP is a key element of modern food safety management practice such that design, implementation, control and management of HACCP systems are crucial to the production of safe food products. Whilst it is widely accepted that food companies should apply HACCP, understanding of the factors impacting successful HACCP application is limited and this knowledge is important to the delivery of systems that will control all relevant food safety hazards. HACCP principle 1, Conduct a Hazard Analysis, forms a central pillar of any HACCP plan since hazards need to be identified, analysed and understood before effective control measures can be specified. However limited guidance is available to HACCP teams on exactly how to approach the application of this principle. This paper discusses an investigation into the application of HACCP principle 1 by HACCP teams operating within manufacturing sites of a multinational food company. Using a combination of HACCP knowledge testing and HACCP plan assessment, the study identified weaknesses in knowledge of significant hazard identification and errors in the hazard analysis process, including errors in application of structured risk evaluation methods. Findings suggest that this is an area of difficulty for HACCP teams and that further detailed guidance in the application of this HACCP principle is urgently needed.     

Barriers of HACCP team members to guideline adherence

A cognitive-behavior model to evaluate barriers to HACCP guideline adherence by HACCP team members was developed. It was based on the theory of experiential learning where knowledge, attitude and behavior must be sequentially overcome. Twenty-seven HACCP team members from four food processors participated to assess barriers to guideline adherence. Non-awareness to HACCP guideline was a major barrier. The national government was recognized as key source of HACCP information. Commitment to adopt HACCP guideline was established. Also, the need for food processor management to understand that teams must be multidisciplinary to ensure guideline adherence has been established.     

Implementation of HACCP and prerequisite programs in food businesses in Turkey

The objectives of this study was to determine food safety practices and procedures related to the hazard analysis critical control point (HACCP) programme and prerequisite programme implementation in food businesses. One hundred and nine food businesses in Turkey were assessed for HACCP-prerequisite programmes and food safety practices. Only eight food businesses had implemented the HACCP system in food businesses. Directors and employees often have insufficient knowledge regarding the basics of food hygiene. Results indicated that proper food safety practices and prerequisite food safety programmes for HACCP were often not being followed in many food businesses. Time and temperature errors and inadequate handwashing practices were wide in the most food businesses. Emphasis on implementing prerequisite programmes in preparation for HACCP is needed in food businesses. The problems of implementing HACCP in food businesses have been namely a low level of food hygiene management training, high staff turnover rate, lack of motivation, lack of financial resources, inadequate equipment and physical conditions of the facility and failure of government.     

HACCP in small companies: benefit or burden?

This paper acknowledges the importance of small companies across the food chain and identifies the slow uptake of HACCP in these companies as an area of concern for the production of safe food. This sets the scene for an analysis of the barriers to HACCP implementation which include availability of appropriate training in HACCP methodology, access to technical expertise and the general resource problems of time and money. The burden that this places on the small business, particularly in terms of documentation, validation and verification, are then discussed. The paper concludes with a summary of the burdens and benefits that this sector faces as it moves towards compliance with food safety legislation.     

HACCP in the United Kingdom

Formal UK Government initiatives to encourage the implementation of HACCP based control systems began in the early 1990s. Early consideration was given to HACCP training activities for both industry and food control officials.In the early 1990s HACCP systems were increasingly introduced by the UK food industry through supplier specification requirements. From 1993 onward, legal requirements for HACCP based controls were progressively introduced through European single market legislation. Subsequently a range of central UK guidance has been produced to encourage and assess HACCP based control systems in UK food businesses.     

An assessment of the value of documenting food safety in small and less developed catering businesses

Current legislation requires food businesses to identify and control food hazards by focussing on critical factors which directly affect the safety of food. This study, commissioned by the Food Standards Agency (FSA) compares the standards of food hygiene in seventy food premises operating either documented or undocumented hazard analysis systems within the Derby City Council boundary.Food hygiene standards were evaluated from purchase of foodstuffs to service of meals to customers. Scores were awarded for the implementation of controls integral to hazard analysis, based on epidemiological data. The only stages in production where a significant difference in standards existed was during preparation and cooking. That is, the standards of hygiene were better during preparation and cooking in those premises with documented hazard analysis systems compared to those operating undocumented systems. The findings highlight problems associated with ineffective monitoring of temperatures, particularly at cooking and cross contamination resulting from poor cleaning practices.The study has important implications for future development of hygiene legislation, particularly if Government is committed to require 30% of UK food businesses to implement full HACCP by April 2004.     

HACCP-based program for on-farm food safety for pig production in Australia

The standard Codex HACCP approach was modified to allow a hazard analysis and critical control point determination to be conducted at an industry level and then used to determine the appropriate on-farm food safety control measures for pig production in Australia. A detailed risk-based profile with hazard identification, hazard characterisation and levels of microbial contamination for production and primary processing was used as a major technical resource to inform HACCP determinations. The process resulted in the identification of Critical Control Points for control of a specific physical hazard (non-recovered broken needles) and prevention of violations of Maximum Residue Limits with agricultural and veterinary chemicals. In relation to the identified microbiological hazards, it was noted that there are numerous Good Agricultural Practices (GAP) to prevent and/or reduce their risk and these controls would also need to be a feature of any on-farm food safety program. By applying a HACCP-based approach it was determined that the application of a set of Good Agricultural Practices on-farm would be effective in ensuring low risk. It was, therefore, concluded that on-farm food safety programs may not warrant full (i.e. Codex compliant) HACCP plans at the individual enterprise level provided appropriate GAP is in place. The results provide pig producers and the Australian pig industry with the elements of a HACCP-based food safety system that are scientifically justifiable, understandable and realistic to apply. These features are essential elements that underpin successful implementation and compliance by industry.     

HACCP effectiveness between ISO 22000 certified and non-certified dairy companies

The purpose of the study is to determine the differences between the ISO 22000 certified and non-certified dairy companies with regard to the HACCP (Hazard Analysis Critical Control Points) Food Safety System (FSS) effectiveness. The HACCP FSS effectiveness is defined in the present study as the degree of the achievement of the system objectives (identification, assessment and the control of food borne safety hazards). A research study was carried out in 74 Greek dairy companies using a structured questionnaire. The differences between the ISO 22000 certified and non-certified dairy companies (both implementing HACCP principles) with regard to HACCP effectiveness are determined through non parametric tests such as the Chi-square Test and the Mann–Whitney Test. The vast majority of the participating in the present study dairy companies are small and medium-sized enterprises (SMEs). The ISO 22000 certified dairy companies significantly outperform the non-certified with regard to the HACCP FSS effectiveness, in other words to the degree to which the objectives of HACCP are achieved. Thus, managers of dairy SMEs taking advantage of the structured organization and the documented procedures provided by the ISO 22000 standard can increase the level of achieving the objectives of the HACCP FSS, in other words HACCP effectiveness. In doing so, dairy SMEs can set the foundations in order to optimize the conditions under which safe food is provided, minimize the possibility of food non-conformities and scandals, increase market share and consequently withstand the current downturn.     

Hazard analysis in hygienic engineering

Hygienic engineering is an essential part of any microbiological quality assurance system, designed to produce foods which will not cause foodborne diseases. Hazard analysis will automatically lead to the determination of critical control points where growth of, survival of or contamination with microorganisms can occur. Hygienic engineering should lead to the elimination of these points, or, if this cannot be achieved, engineering should create conditions which will allow these points to be kept under control. For hazard analysis, some basic knowledge about the behaviour of microorganisms is needed in order to understand some general rules that apply in most situations where product safety has to be built in. More expertise may be needed to estimate the severity and the likelihood of occurrence of specific hazards in a given production line. Teamwork between engineers, hygienists, food technologists and microbiologists is essential to assure safety. Hazard analysis should be carried out systematically for all new factory projects, line extensions, changes in lines, new products etc., in order to be effective. Some examples are given to illustrate the HACCP concept and how to carry out hazard analysis.     

Barriers for the developing and implementation of HACCP plans: results from a Spanish regional survey

Despite the fact of compulsory HACCP plan in the regulations, their development and implementation is being difficult and slow. This paper present a survey in an area of Madrid to identify the barriers which are obstructing the implementation of HACCP programs in food companies, following the model of eleven potential barriers organised around three levels proposed by Gillings et al. [J. Food Protect. 64(5) (2001) 710]. The results suggested that lack of understanding and negative guideline factors conduce to inadequate hazard analysis, and this is not solved contacting external advisers. There are also problems at attitude level which obstruct the change of behaviour.It is suggested that regulatory agencies should work to publish clear and detailed HACCP guides in Spanish and to promote activities aimed to external consultants and industry managers and directives.     

A review of the needs and current applications of hazard analysis and critical control point (HACCP) system in foodservice areas

The reported food related illness per year was 76 millions cases in the US [Food Control 13(6–7) (2002) 363] and 9.4 millions in the UK [Food Control 14 (2003) 169], and this data indicated that there are still needs for improvement in the food production chain. The food service area is one of the last hurdles for food items in the food chain and, millions of people eat out or utilize catering services each year which stresses the need for an improved system of food safety in food service. Also, in the food service area, especially in small or medium size food business there visually appears to be a tremendous need for a better system than is currently in place.Research [Food Control 14 (2003) 169; Food Control 11 (2000) 447] showed that education with knowledge of food safety and proper food handling are needed and will help the food service personnel (workers and managers) with a better understanding in food service and better hygiene practices which resulted in safer foods. Besides, risk assessment, HACCP has been applied in most of the food production areas. For most of the food chain, HACCP is mandatory by law and government's regulations. There appears to be needs for applying Pre-requisite Programs (PRP) [Food Control 14 (2003) 169; Irish J. Agric. Food Res. 39 (2000) 221] and later HACCP in food service areas to ensure the safety of food consumption in the total food chain [Food Control 12(3) (2001) 165] since a chain is no stronger than its weakest link. This paper will discuss the needs, current applications and the prospects of HACCP in food service areas.     

Compliance in slaughterhouses and control measures applied by official veterinarians

Implementation of well-functioning hazard analysis and critical control point (HACCP)-based self-checking systems (SCSs) is crucial for meat safety in slaughterhouses (SHs). However, if these SCSs fail, control measures used by official veterinarians (OVs) should be efficient enough to secure the safety of the meat. To examine the control measures used by the OVs and the cases of noncompliance in the implementation of SH SCSs, we issued a survey to the chief OVs in high-capacity SHs in Finland during spring 2014. The expertise of the OVs and the quality of guidance they received were also examined. Our results showed that the most common and severe cases of noncompliance in the implementation of high-capacity SH SCSs in Finland were associated with hygiene. Those SHs with high frequencies of noncompliance were all smaller high-capacity units in which written time limits for correction of noncompliance and enforcement measures were less commonly used. Most OVs felt that they did not receive sufficient competent guidance in performing food safety inspections, and in some SHs the expertise of the OVs in administrative procedures and food safety legislation should be improved. To further ensure meat safety, OVs, especially in SHs with high frequencies of noncompliance, should be encouraged to use more effective control measures.     

HACCP-based approach to the derivation of an on-farm food safety program for the Australian red meat industry

The standard Codex HACCP approach was modified to allow a hazard analysis to be conducted at an industry level which could then be used to derive appropriate on-farm food safety control measures for cattle, sheep and goat production in Australia. Scientific information from a through chain risk profile of the red meat industry was used as a major resource for the hazard analysis. The process resulted in the identification of critical control points for control of bovine spongioform encephalopathy (BSE), prevention of violations of maximum residue limits with agricultural and veterinary chemicals and infection with Cysticercus bovis (Beef Measles). By applying this HACCP-based approach it was determined that the application of a simple set of good agricultural practices (GAP) on-farm would be effective in ensuring low risk. It was, therefore, concluded that on-farm food safety schemes may not warrant full HACCP plans at the individual enterprise level as long as appropriate GAP is in place. The results provide red meat producers with the elements of a HACCP-based food safety scheme that is scientifically justifiable, understandable and realistic to apply which are essential elements that underpin successful implementation and compliance by industry. Subsequently, an on-farm food safety program has been developed to provide an appropriate level of protection for consumers as well as to protect Australia’s trade from food safety-related issues.     

Managerial attitudes, acceptance and efficiency of HACCP systems in Hungarian catering

The Hungarian catering industry has to face up to numerous challenges nowadays because of rising costs and stagnating purchasing power. Under these conditions the managerial acceptance of the compulsory introduction of the HACCP system is rather mixed. This research is based on a direct question survey, with the aim of analysing the relation amongst the strategies of catering service managers, their attitudes towards food hygiene and the HACCP system, their managerial experiences about working with the HACCP system, as well as the evaluation of hygienic practice of catering service providers by independent specialists. More than 1100 questionnaires were processed. Two main approaches were analysed with regard to the general attitudes of catering managers: the hygiene and the cost-oriented approaches. The acceptance of HACCP systems lacked homogeneity to a significant extent. 28% of the respondents considered that the increasing quality and safety were the really important and necessary tasks. 41% of the respondents had a rather reluctant attitude towards their systems, mainly as a consequence of fear of extra investment and administrative burdens. Last but not least, the third group of managers accepted the importance of hygiene, but did not acknowledge the possibilities offered by HACCP for better work-organisation and clearer determination of responsibility. The structural equation analysis between the managerial strategy and attitudes, as well as the hygienic conditions, have proven numerous significant relations between these factors, but the results highlight the importance of efforts aiming at better integration of the HACCP approach in managerial activities. There is a real danger that this system will be simplified to accomplish administrative tasks.
