BEIJING — Two giant toxic red tides engulfed parts of the sea off northeastern China over the weekend, and officials were monitoring seafood for contamination, the China Daily reported on Wednesday.
Marine experts said the red tides would grow, but so far shellfish and other seafood were safe to eat despite the algae blooms, the newspaper quoted the State Oceanic Administration as saying.
EDIT
The newspaper said one of the blooms emerged on Friday near the mouth of the Yellow River and covered about 1,850 sq km (710 sq miles) of the Bohai Sea. The other blanketed an area covering about 3,200 sq km (1,240 sq miles) near the northern port city of Tianjin.
The newspaper said the red tides were part of a rising trend, and in May China's coastal areas were hit by 34 outbreaks affecting more than 10,000 sq km (3,860 sq miles), a rise of 3,000 sq km (1,160 sq miles) from the year before."
