Safety Considerations for Handling Imported Fire Ants ( Solenopsis Spp. ) in the Laboratory and Field

Abstract

Imported fire ants pose two primary threats to humans: the risk of anaphylaxis following stings, and the potential for secondary infection of localized pustules that result from stings. Additionally, fire ant products such as whole-body extract and venom can present risks to laboratory personnel. Whether in concentrated form in the laboratory or retained within the living animal, fire ant venom alkaloids and proteins are biological toxins with potentially severe health effects. Several recommendations are given for minimizing the risk of stings in the laboratory and field with the understanding that most experienced workers are capable of assessing their own tolerance to stings and acting accordingly. Since there are no fail-safe methods for avoiding fire ant stings, all workers who are exposed to imported fire ants should be familiar with the symptoms of anaphylaxis and be prepared to seek immediate medical assistance if they or their coworkers are stung and show symptoms of hypersensitivity.
