Abstract
Attitudes towards pesticides are often irrational. International organizations have tended to be preoccupied with questions of residues and ‘acceptable daily intakes’ but have been slow to act in preventing recurrence of tragedies through release of chemically treated seed grain for human consumption or through contamination of food by spillage of pesticides transported in unsuitable containers. Governments have imposed or recommended few restrictions on the manufacture and distribution of some of the most toxic materials for which safer substitutes are already available.
