Due to food safety concerns in China, Chinese tourists are flocking overseas to places like Australia to buy infant formula. They are emptying the shelves so fast that some stores are limiting purchase to two containers per customer. In 2009, six children died and 300,000 were made sick from infant milk formula that had melamine, an industrial chemical. An Australian company, Nutricia, said it had to increase its production of infant formula from 5,000 tons to 20,000 tons in 2012.
