Tainted Coffee Prompts Tighter Security at Harvard Research Building

Harvard Medical School is adopting additional security measures at its New Research Building, in Boston, after an incident in which six researchers were sickened in late August by coffee tainted with a laboratory chemical, The Boston Herald and The Wall Street Journal reported. In a written statement released on Friday, the medical school described the measures as precautionary, saying it did not know how the coffee had become contaminated. The university police and federal and city health officials were investigating. The researchers all work in the school’s pathology department and use mice to study the immune system.
