TEMPE, Ariz., April 24 (UPI) -- Heating leftovers in the office microwave can leave possible toxins in the food and cold spots that harbor bacteria, a U.S. expert says.
Rolf Halden, the director for the Center for Environmental Security at the Biodesign Institute at Arizona State University, said the level of chemicals leaching into food while being reheated in the microwave depends on the type of plastic put in the microwave, the time it is heated and the physical condition of the container, The Wall Street Journal reported.
