Egg stamping now mandatory in SA

All South Australian eggs must now be stamped with a unique identification mark of their producers, providing consumers with a ready means of determining origin and aiding in traceability.
All egg producers selling eggs must comply with the new code, which covers eggs and egg products.
Producers with less than 50 chickens don't have to be accredited as long as they don't sell their eggs to food businesses or at farmers' markets. The majority of eggs will be stamped with "SA," followed by a number to identify the farm.
To gain accreditation, producers need to contact Bioecurity SA, adopt a food-safety statement, comply with the new standards and pay an annual fee. The fees start at $175 for up to 1,000 hens and rise to $650 for 1,000 to 9,999 hens. Higher charges apply for larger farms.
It's a pity that the Victorian Government has delayed the impementation of egg stamping here because it's a good way to combat egg substitution problems.
