Microbiological investigation and nutritional evaluation of selected fast food meat

ABSTRACT

The study was designed into two parts the first part was to determine individual attitudes and beliefs toward fast food in general. One hundred individuals [15-45 yrs old] were involved in this study [50 males and 50 females]. The second part of the study was carried out to evaluate microbiological contamination and nutritive value of the selected fast food meat [Hardee's fried burger, Saudi-American burger, kentucky fried chicken, Al-Baik broast chicken and shawerma beef]. The results indicated that individuals 25-45 yrs. old were the most fast food consumers. The main reason behind increasing individual's preferences toward fast food was found to be for fun and inspiration. Among individuals under study 46% of males and 20% of females purchased fast food more than 4 times per week. Prevalence of overweight and obesity respectively were 38% and 22% among males and 34% and 14% among females. Bacillus cereus and E. coli were detected in a number of less than 10/g in all the selected fast food meat. The number of coliforms detected in Hardee's burger and Saudi-American burger were 10/g, while less than 10/g were detected in the remaining fast food meat. However, the number of Staph. aureus detected in Hardee's burger and Saudi-American burger was 20/g and big respectively. On a per 100 g basis, energy [Kcal], protein [g], fat [g] and sodium [mg] content were found in the range of 179.62-295.29, 13.05-26.06, 8.9-21.13 and 640- 920 respectively. Sodium content of all the selected fast food - meat exceeded the recommended daily adequate intake for adults [males and females]. The observations of the present study indicated the need for a nutrition education program to correct consumers' attitudes and beliefs towards fast food and to provide information on how a given menu item contributes to their dietary goal
