“…The 83-year-old man dying in the 1971-5 period may also have worked for the Ministry, but this remains unconfirmed. The search for deaths among the 360 rodent operatives exposed to ANTU listed by local authorities revealed only four cases already known from other sources (5,6,8,10); had this source alone been used, the deaths of cases 1, 2, and 9 would have been missed. In addition, one local authority reported a current employee to have been treated for a bladder tumour (11), but this man had had only slight exposure to ANTU and his tumour was probably attributable to earlier exposure to carcinogens in a chemical factory.…”
