Effectiveness of petrifilm analyzing assay in hygiene quality management in restaurant in hotel

This research evaluated the microbiological hazards existing on foods, drinks and cooking utensils in restaurants. Evaluation was based on bacterial enumeration of total plate count or TPC (cfu/g), Enterobacteriaceae (cfu/g), Coliform (cfu/g) using the Petrifilm analyzing protocol compared to traditional pour plating on 198 food samples, 198 drink samples and 198 utensil samples taken from 11 restaurants in 11 hotels from 01/06/2019 to 30/12/2019 in Da Nang city, Vietnam. Results showed that there were not significant difference of data accounted by Petrifilm testing and conventional pour plating in respect of aerobic plate count, Enterobacteriaceae, Coliform. Petrifilm revealed available, reliable, accurate and manipulate easily in enumerating hygienic criterias. It would be an appropriate alternative to save cost and time-consuming for microbioligcal quality management in restaurants.
