National food standard safety -
Disinfected dinner and drinking sets
1 Scope
This Standard specifies the hygienic requirements for disinfected dinner and

The surfaces of the dinner and drinking sets shall be smooth, with no
attachment, oil stain, foam or odor.
2.2 Physicochemical indicators
The physicochemical indicators shall conform to the provisions of Table 1.

Methods for detection of coliforms
Note. These methods are applicable to the detection of coliforms for dinner and drinking sets.
B.1 Fermentation method
B.1.1 Medium
B.1.1.1 Lauryl sulfate tryptose (LST) broth. 10mL per tube.
B.1.1.2 Double-strength lauryl sulfate tryptose (LST) broth. 10mL per tube.
B.1.2 Fermentation and result observation
B.1.2.1 Chopsticks. In case of swabbing the sample with a cotton swab,
directly PLACE the sampled cotton swab in lauryl sulfate tryptose (LST) broth.
In case of sampling by shaking the saline, directly ADD sampled 10mL of liquid
to double-strength lauryl sulfate tryptose (LST) broth. CULTURE the mixture for
24h to 48h at 36°C ± 1°C.
B.1.2.2 Other dinner and drinking sets. Directly PLACE the sampled cotton
swab or all test paper in lauryl sulfate tryptose (LST) broth. CULTURE the
mixture for 24h to 48h at 36°C ± 1°C.
B.1.2.3 Result observation and subsequent re-fermentation test. CARRY out
in accordance with the methods specified in GB 4789.3.
B.2 Paper strip method
B.2.1 Medium
USE special rapid test paper for detection of coliforms, in the size of 5cm × 5cm
(with an area of 25cm2).
B.2.2 Culture and result observation
PLACE the sampled rapid test paper for detection of coliforms at 36°C ± 1°C
for 16 to 18 hours of culture. OBSERVE the results afterwards. The results shall
be determined according to the product manual.
B.3 Quality requirements
B.3.1 For the detection of coliforms for dinner and drinking sets, both
