A senior scientist at Consumers Union told "Squawk Box" that the U.S. regulators need to step-up inspections of food coming from China, particularly seafood.
According to the Consumer Union's Michael Hansen, the U.S. has been getting an increasing amount of its seafood from China. About 20% to 22% of all U.S. seafood comes with China, but for certain types of fish the percentages are greater, he said. For example, 87% of all eel comes from China and 12% of all shrimp, he said.
Although unprocessed seafood lists its country of origin, processed seafood does not, he said. This puts more a burden on the FDA, he said.
