Melamine hysteria #8 - Minimum acceptable levels

Finally....finally the AVA (Agro-Food and Vet Authority) has released its acceptable limits for melamine. They are:

• 1 part per million (ppm) melamine, for food products for children below 3 years of age, and

• 5 ppm for all other food products.

These are extraordinarily tolerant compared to other jurisdictions. The US FDA, and most other countries following suit, have used 2.5ppm of melamine plus related compounds. For reasons best known to itself, AVA has used a limit that is at least twice as lenient compared to other agencies.

I am puzzled. Care to explain, AVA?
