NGOs, others can also check food quality

The recall of more than 8,200 tons (previously reported to be 700 tons) of Sanlu-brand "problem infant formula" is a problem bigger than just one brand and one company.

Up to now, it looks still contestable at which stage of the entire business process the poison, a chemical called melamine, got the access to contaminate what used to be the No 1 selling infant milk formula in this country.

The complexity of the problem betrays the complexity in policing for food security in an industrial environment. There are many potential loopholes, therefore many sources are to be mobilized to police them - not just one or two government agencies, and not just one or two companies.
