Concern has been raised over the infection risk of the TASER electrical weapon since the probes penetrate the skin. The manufacturing process produces unsterilized probes with a 5% rate of Staphylococcus aureus contamination. Voluntary recipients (n = 208) of probe exposures were surveyed and there were no self-observations of infection. With over 3.3 million probe landings, there have been 10 case reports of penetrations of sensitive tissue with no reported infections. The electrical field was modeled and found that the electrical pulses generate a field of over 1200 V/mm on the dart portion. This is sufficient to sterilize the dart via electroporation. Electrical weapon probes appear to have a very low (possibly zero) rate of infection. The factors leading to this low infection rate appear to be a manufacturing process producing a low rate of bacterial contamination and the pulses sterilizing the dart via electroporation.
自泰瑟电击武器的探针穿透皮肤以来，人们对其感染风险表示担忧。制造过程会生产出未消毒的探针，金黄色葡萄球菌污染率为5%。对自愿接受探针暴露的208名受试者进行了调查，未发现有自我感染的情况。在超过330万次探针着陆中，有10例关于敏感组织穿透的病例报告，均未报告感染情况。对电场进行建模后发现，电脉冲在镖头部分产生的电场超过1200 V/mm。这足以通过电穿孔使镖头消毒。电击武器探针的感染率似乎非常低（可能为零）。导致这种低感染率的因素似乎是制造过程中细菌污染率低以及电脉冲通过电穿孔使镖头消毒。
