Summary
Among
the causes of acute methemo-globinaemia are the ingestion and inhalation
of over 40 oxidising substances, including nitrite, nitrate, carbon
monoxide, some medicines, chlorine. The authors describe a case
of acute methemoglobinaemia in two people that most probably suffered
from food poisoning resulting from the consumption of a preparation
of a dish called turkey alla canzanese that contained significant
amounts of sodium nitrite. Both subjects who were treated promptly
with methylene blue and hyperbaric oxygen therapy room recovered
fully. Epidemiological investigations performed to clarify the dynamics
of the episode suggested that among the causes of contamination
were the swapping of products at the time of sale and the non-compliance
to rules for the preparation of foods for human consumption.
