| Popis: | 105 The prevalence of food scandals has increased in recent years. Scandals involving pesticide residue in tea leaves that exceed regulations are particularly frequent, thus highlighting the importance of autonomous management and responsibilities for beverage vendors. Three large beverage franchises in a county in Southern Taiwan were employed as subjects in the present study. A food safety supervision program was introduced to offer guidance and elucidate relevant concepts, thereby facilitating the subjects in conducting autonomous management. Samples were taken before and after the introduction of the program. Two methods of testing pesticide, namely Multiresidue analysis, and a dithiocarbamate test, were conducted on black tea, green tea, qingcha (dark green tea), and oolong tea to determine the performance of the franchises’ autonomous management and management models. The results indicated that although companies A, B, and C adopted different measures and models when implementing autonomous management, all three subjects exhibited a significant reduction in pesticide residue following the introduction of the food safety supervision program. Companies A and B showed superior and similar performances in autonomous management. Prior to program intervention, 26 types of pesticide residue were found in company A’s products, 24 of which were eliminated following program intervention, which translates to a reduction rate of 92.31%. Twenty-four types of pesticide residue were found in company B’s products, 21 of which were eliminated following program intervention, which translates to a reduction rate of 87.31%. Twenty-seven types of pesticide residue were found in company C’s products, 16 of which were eliminated following program intervention, which translates to a reduction rate of 40.74%. When considering the type of tea, qingcha contained the most types of pesticide residue for all three companies, whereas black tea contained the least types of pesticide residue. The results of the present study also indicate that having professionals teach farmers to use pesticides correctly, offering subsidies to farmers who limit pesticide use, conducting inspections for every batch of tea leaves, increasing inspection frequency, and releasing product inspection reports to consumers are management models that contribute to a significant elevation in the performance of autonomous management. The results of the present study can serve as a reference for other beverage franchises in implementing autonomous management. |
