Appendix A
Sampling Method for Dinner and Drinking Set
A.1 Dinner and drinking set sampling of physical and chemical indexes
A.1.1 Wash the whole internal surface (in proportion of 100mL distilled water per 100cm2 of surface area) of the to-be-inspected dinner and drinking set (bowl, plate, dish, mug, and goblet etc.) with distilled water in 3~5 times and prepare it into the sample solution for standby.
A.1.2 Put the lower section of spoon (excluding the spoon handle) and chopsticks (about 5cm on the inlet) into proper amount of distilled water (in the proportion of 100mL distilled water per 100cm2 of surface area), sufficiently shake for 20 times and prepare it into the sample solution for standby.
A.2 Dinner and drinking set sampling of microbiological index
A.2.1 Dinner and drinking set sampling of coliforms (fermentation method) and pathogen indexes
A.2.1.1 Chopsticks: take 5 chopsticks as a sample. Put the portion of 5cm (length 5cm×perimeter 2cm×5 pieces, 50cm2) from lower section (inlet) of these 5 chopsticks into the 10mL large test tube filled with sterilized normal saline and transfer chopsticks out after sufficiently shaking for 20 times. According to the specific conditions, these 5 chopsticks may be shook respectively. Or uniformly smear the area covering 5cm surface from the lower section (inlet) of these 5 chopsticks respectively with the cotton swab moistened with aseptic normal saline for 3 times, cut out the part of cotton swab contacting with hand with sterilized scissors and place the cotton swab into corresponding fluid culture medium.
A.2.1.2 Other dinner and drinking set: moisten 10 pieces of 2.0cm×2.5cm (5cm2) sterilized filter paper (with the total area of 50cm2) with 1mL aseptic normal saline. Stick 10 moistened sterilized filter papers on each sample respectively, which is selected from the inner wall surface of dinner and drinking set generally contacting with food or the contact area with lips. Take down after 30s and place them into corresponding fluid culture medium. Or uniformly smear the overall square in 2 area ranges of 25cm2 (5cm×5cm) with the cotton swab moistened with aseptic normal saline for 3 times, cut out the part of cotton swab contacting with hand with sterilized scissors and place the cotton swab into corresponding fluid culture medium. Deliver it for inspection within 4h.
