Incidence of Ciguatera fish poisoning in Puerto Rico.

Ciguatera fish poisoning (CFP) is the most common seafood intoxication worldwide, but its incidence has been difficult to establish because there are no biomarkers to diagnose human exposure. During 2005 and 2006, Azziz-Baumgartner et al. (p. 526) conducted a census of all occupied households on the island of Culebra, Puerto Rico, where locally caught fish are a staple food. The authors surveyed 340 households during 2005 and 335 households during 2006, seeking information about household demographics, consumption of local fish, the amount and type of fish eaten, and any illnesses experienced after eating a fish meal during the previous year. CFP case-patients were defined as persons with gastrointestinal symptoms (i.e., abdominal pain, vomiting, diarrhea, or nausea) plus neurological symptoms (i.e., extremity paresthesia, arthralgia, myalgia, malaise, pruritus, headache, dizziness, metallic taste, visual disturbance, circumoral paresthesia, temperature reversal, or toothache) or systemic symptoms (e.g., bradycardia) within 72 hr of eating a fish meal. The estimated annual incidence was 4.0 per 1,000 person-years for possible CFP and 7.5 per 1,000 person-years for probable CFP. These estimates are consistent with previous studies and can be used to support public health decisionmaking about the prevention of CFP.
