Analysis of mushroom exposures in Texas requiring hospitalization, 2005-2006

J Med Toxicol. 2009 Jun;5(2):59-62. doi: 10.1007/BF03161087.

Abstract

Introduction: Texas has approximately 200 species of wild mushrooms, including toxic and hallucinogenic varieties. Mushroom ingestions in Texas were studied for 2005-2006.

Methods: Data was obtained via Texas Poison Control Centers and retrospectively reviewed. Case notes were reviewed individually regarding initial reporting, age, signs and symptoms, toxic effect, management, and patient outcomes.

Results: A total of 742 exposures occurred during the study period. All exposures were acute and intentional. Of these exposures, 59 (7.9%) were admitted to the hospital, with 17 (28.8% of admissions) requiring admission to a critical care unit. Four cases required inpatient psychiatric admission. The average age of admitted exposures was 20.5 years, with a male-to-female predominance of 3.3:1. Eleven (22.9%) of the admitted exposures were identified, with Psilocybin being the most common agent (n = 10, 91%). Among the admissions, co-ingestions were identified with the mushroom ingestion in eleven patients (40.7%). The most common symptoms in admitted patients were vomiting (n = 34, 57.6%), nausea (n = 19, 32.2%), altered mental status (n = 17, 28.8%), abdominal pain (n = 13, 22%), and diarrhea (n = 10, 16.9%).

Conclusions: All mushroom exposures examined were acute and intentional. Major toxic reactions were uncommon, and no deaths were reported. Serious poisoning from mushroom ingestion is rare in Texas; however, there is greater need for information dissemination on morbidity.
