The material (such as glass, stainless steel, plastic, etc.) and structure of the sample container
shall be able to fully ensure the original state of the sample. Containers and lids shall be clean,
sterile, and dry. The sample container shall be of sufficient volume so that the sample can be
fully mixed before testing. The sample containers include sampling bags, sampling tubes,

The number of sampling pieces n shall be implemented in accordance with the requirements of
relevant food safety standards. The sampling volume of each sample shall be no less than 5
times the sample of the inspection unit, or determined according to the purpose of inspection.
The following specifies the sampling requirements for a food sample.
3.2 Prepackaged condiments
3.2.1 Solid or semi-solid condiments with an independent packaging volume of less than or
equal to 1000g, or liquid condiments with an independent packaging volume of less than or
equal to 1000mL shall be individually packaged in the same batch.
3.2.2 Solid or semi-solid condiments with an independent packaging volume of larger than
1000g, or liquid condiments with an independent packaging volume of larger than 1000mL can

4 Sample Treatment
4.1 Unpack the package

placed. For packaging in plastic or cartons (bags), use 75% alcohol cotton balls to sterilize the
lid or bag mouth; and cut it with sterilizing scissors. For packaging in bottles (buckets), sterilize
by 75% alcohol cotton balls or flame; and aseptically remove the bottle (bucket) cap and bottle
(bucket) mouth, and then sterilized by flame again.
4.2 Dilution
4.2.1 After weighing or quantifying the sample to be tested, dilute the sample to a volume of
1:9. After mixing, the diluted solution can be stirred if there are large particles. If the 1:9 dilution
is too viscous, the volume of the diluent can be increased. If a concentration higher than the 1:9
first dilution is required to obtain experimental results, the volume of the diluent can be
appropriately reduced. If the estimated number of bacteria in the sample is less than 10 CFU/g,
the first dilution shall be used. If the bacterial content is lower, the volume of the dilution can
be appropriately reduced.
