This paper, an account of the Shetland Islands oil spill (1993), exami
nes the public health controversies surrounding the spill and the clea
n-up response. It critically examines the risk management policies of
both the United Kingdom and the Shetland Islands Public Health Office,
and suggests that the withholding of critical information contributed
to increased anxiety and suspicion among the disaster victims. In an
attempt to reassure the victims, the policies contributed to an increa
sed air of uncertainty. It is further argued that the withholding of i
nformation prevents those who are at greatest risk from participating
in critical decisions that may affect their health and livelihoods and
asserts that a right-to-know policy is a critical first step in risk
management practices.
