Wild mushroom exposures in Florida, 2003-2007

Area of Science:

• Toxicology
• Epidemiology
• Public Health

Background:

• Wild mushroom ingestion poses significant health risks, including severe illness and fatalities.
• Nationwide epidemiological data on mushroom exposures are limited due to a lack of specific surveillance.
• Understanding regional exposure patterns is vital for targeted prevention strategies.

Purpose of the Study:

• To describe the epidemiology of wild mushroom exposures in Florida.
• To utilize existing data sources for a population-based analysis of mushroom-related incidents.

Main Methods:

• A population-based study analyzed mushroom exposure calls to the Florida Poison Information Center Network (FPICN).
• Hospital inpatient and emergency department (ED) data from 2003–2007 were reviewed for mushroom poisoning cases.
• Data were combined to identify unduplicated mushroom exposure events.

Main Results:

• 1,538 unduplicated mushroom exposures were reported, with 1,355 calls to FPICN and 428 hospitalizations.
• Exposures predominantly involved males (64%) and children ≤6 years (45%), often as unintentional ingestions (60%).
• While most exposures had no or mild effects, 23% resulted in moderate symptoms, and 1% had life-threatening outcomes; no deaths were reported.

Conclusions:

• Mushroom exposures in Florida disproportionately affected males, young children (≤6 years), and young adults (16–25 years).
• A significant majority (78%) of cases involved contact with a healthcare facility.
• Public health education should target parents of young children and young adults, particularly during peak mushroom seasons.
