Case Definition: Sulfuryl Fluoride
Sulfuryl fluoride poisoning usually occurs after inhalational exposure. The predominant manifestations of sulfuryl fluoride poisoning are respiratory irritation and neurologic symptoms. Adverse health effects of acute poisoning usually include lacrimation, nasal or throat irritation, cough, dyspnea, paresthesias, electrolyte abnormalities, and possibly seizures (1-3).
Laboratory criteria for diagnosis
- Biologic: No specific test for sulfuryl fluoride exposure is available. However, an elevated fluoride concentration in the serum, hypocalcemia, and hyperkalemia might indicate that an exposure has occurred. Normal serum fluoride concentrations are <20 mcg/L but it varies substantially on the basis of dietary intake and environmental levels. (1-3)
- Environmental: Detection of sulfuryl fluoride in environmental samples. (4-8)
- Suspected: A case in which a potentially exposed person is being evaluated by health-care workers or public health officials for poisoning by a particular chemical agent, but no specific credible threat exists.
- Probable: A clinically compatible case in which a high index of suspicion (credible threat or patient history regarding location and time) exists for a sulfuryl fluoride exposure, or an epidemiologic link exists between this case and a laboratory-confirmed case.
- Confirmed: A clinically compatible case in which laboratory tests on environmental samples are confirmatory.
The case can be confirmed if laboratory testing was not performed because either a predominant amount of clinical and nonspecific laboratory evidence of a particular chemical is present or a 100% certainty of the etiology of the agent is known.
