The constant development across markets, imposes two new challenges: non-harmonisation and lack of clarity.
Non-harmonisation leads to complexity for food manufacturers. For example, Australia and the US both use the “Contains” statement for allergen declaration, but they do not recognise the same allergens.
Consider molluscs for example: they are recognised as allergens in Australia, requiring declaration in the ingredient list and mandatory inclusion of a “Contains” statement for molluscs and products thereof. However, molluscs are not recognised allergens in the US, prohibiting the use of a “Contains” statement for these ingredients in this market. This divergence poses a labelling challenge for both importers and exporters.
