The evaluation of implementing the HACCP system in contract catering companies and assessment of the knowledge, attitudes and practices of the food handlers were the main objectives of this study. It was conducted in 20 companies throughout Spain, with visual inspection of facilities and food handler activities, as well as the distribution of a self-administrable questionnaire among the 105 participant catering workers. In addition, samples of surfaces and finished dishes were taken from each kitchen for microbiological evaluation. The results obtained from the questionnaires reflect extensive knowledge and correct behaviors among respondents with a middle-or highschool educational level, stability in the same workplace and positions of greater responsibility. However, the observation of hygiene practices revealed systematic incorrect procedures in 60% of the kitchens. Most observed deviations were related to the lack of HACCP training and information, the temperature of finished dishes, the storage areas and proper cleaning and disinfection. In summary, this study confirms the difficulties inherent in catering companies to effectively implement the HACCP system, such as the lack of well-trained personnel, lack of motivation or adhesion to said system on the part of the workers, and the lack of financial and economic resources to address the deficiencies in the facilities. Specific educational programs and grants are need for an adequate implementation of HACCP in this sector.

Proper application of HACCP in catering services involves monitoring decisive critical points. The purpose of this study was to assess food temperatures and surface hygiene control in two catering services in Navarra (Spain) at two different time periods: the first one after implementation of the HACCP system and the second period, after the initial supervision through audits and a specific training session regarding temperatures of products and hygienic conditions of surfaces and equipment because the majority of 2 detected nonconformities were related to these parameters. The recorded temperatures of 650 cooked food products within the first period showed that only 65.1% of the hot dishes had a temperature higher than 65 ºC, in accordance with Spanish legislation, and 12.9% of them showed a risky holding temperature (<55 °C). However, the percentage of noncomplying dishes was reduced by a half after the training session (p<0.001).Since the significant differences observed in recorded temperatures were related to the type of meal (with or without sauces) and the type of cooking procedure, a lower safe criterion for the retention of hot dishes was suggested if the temperature is continuously maintained over 55ºC until serving. With regard to cleaning and disinfection, 18.3% of the 600 analyzed surfaces did not meet the established cleaning criterion (≤ 100 CFU/25 cm 2 ) in the first period, while in the second period this percentage was reduced to 13.6% in both catering businesses (p=0.021). The dirtiest surfaces were equipment such as cutting boards and meat slicing machines (>26%) compared to utensils for distribution (12.0%). As the impact of dirty surfaces on the hygienic quality of a finished product will depend on which step was being taken during dish elaboration when equipment or utensil was used, it is suggested that more restrictive limits be established regarding utensils and equipment that are in direct contact with the finished product (≤1 CFU/cm 2 ). Results of the study demonstrate that a specific training session on these items has improved the temperature control of prepared meals and the effectiveness of cleaning and disinfection, essentials for guaranteeing the hygienic quality of prepared foods.

A survey was conducted to investigate the relationship between knowledge about food safety and actual food handling practices among Spanish university students (mainly from the health sciences disciplines) who usually prepare meals at home. Based on level of education in food safety topics, students were divided in three groups: high, which included students from Food Science and Nutrition; medium, which included students from other health sciences; and low, which included students from non-health-related studies. More than two thirds of the 562 people selected had an accurate knowledge of the eight foodborne pathogens included in the survey, but only 5.2% were able to identify Staphylococcus aureus as a foodborne pathogen. Significant differences in responses were found depending on educational level concerning the food safety topic. For food handling, up to 60% of the responses reflected accurate knowledge of proper storage of prepared meals and washing of hands and materials to avoid cross-contamination. However, with the exception of questions related to storage temperature, there was considerable difference between knowledge and reported behavior. Although 98.6% of the participants recognized the importance of hand washing before and during food preparation, only one quarter (24.4%) affirmed that they washed their hands with soap and water. On questions concerning food practices, more accurate answers were given by the older students. Women answered questions regarding cross-contamination more accurately, whereas men were more accurate in response to questions concerning temperature and food preservation. In general, students with more knowledge of food hygiene had better reported practices, but even these students reported some high-risk behaviors. These results confirm the need to improve educational programs, ensuring that the acquired knowledge actually modifies consumer behavior.
