Introduction: Methyl bromide has been responsible for deaths that usua
lly occur from its accidental inhalation during fumigation. Case Repor
t: We report an accidental fatality that occurred after methyl bromide
seeped through underground conduits from a fumigated building to an a
djacent guest house on the same property. The patient developed refrac
tory seizures, intermittent fever, and multiorgan system failure befor
e dying 19 days after exposure. The initial serum bromide was 27 mg/dL
. Postmortem analysis detected methyl bromide concentrations of 2.9 mg
/dL in the blood, 1.7 mg/dL in the bile, 24 mu g/g in the liver, and 2
8 mu g/g in the adipose tissue. Conclusion: Methyl bromide, although a
pplied under acceptable safety standards, led to the inadvertent death
of a young woman. Extreme care must be used when fumigating to insure
no unsuspected seepage routes exist.
