To remind exporters of Vietnam’s microbiological requirements for certain egg products as set out in Vietnam’s Circular 5/2012/TT-BYT of 1 March 2012 Promulgating the national technical regulations on microbiological contaminants in food.

Summary of key points

The department is aware that Vietnamese authorities may undertake port-of-entry testing of imported food, including agg and egg products, to verify compliance with the Circular 5/2012/TT-BYT.  The table below outlines the maximum limits of micro-organisms allowed for certain egg​ products (Circular 5/2012/TT-BYT).

Limits of microbiological contamination in eggs and products from eggs​

No. Product Norm Sampling plan Allowed limit (CFU/ml or CFU/g) Norm rating
n c m M
2.1 Products from eggs Enterobacteriaceae 5 2 101 102 B
Salmonella 5 0 KPH (2) A

(1) for instant-use products
(2) in 25g or 25ml


n: the number of samples from the consignments to be tested.
c: the maximum amount of samples of which the test results are allowed to lie between m and M. For n samples tested, only c samples are allowed to have the test results lie between m and M.
m: lower limit, it is considered passed if all the test results of n samples do not exceed m.
M: upper limit, it is considered failed if only one test result of n samples exceeds M.
KPH: not detected
Norm A: is the norm required to be tested during the conformity assessment.
Norm B: is the norm not being required to be tested during the conformity assessment if the producers already take risk control measures in the production (HACCP or GMP). If the producer omits to take risk control measures, these norms are compelled to be tested.

Consequences for breaches in microbiological limits

Breaches of microbiological limits may result in the consignment being seized and ordered for re-export or destruction, and the importer may be fined.

The department is working with Vietnamese authorities to further its understanding of the application of this regulation and, if possible, improve import conditions.
