After Katrina: tracking the toxic flood

[摘要] Marine researchers are assessing the safety of fish and shellfish exposed to toxic flood waters in the Gulf of Mexico following Hurricane Katrina. The floodwaters are teeming with Escherichia coli and a wide range of chemicals. A team of scientists collected shrimp, oysters and Atlantic croakers and sent them to a laboratory to be tested for bacterial contamination and pollutants. The results are not yet known and serious attention is being paid to food safety along with concern that the hurricane has damaged important fish and shellfish stocks.
