True blister beetles (genus , family Meloidae) produce cantharidin, which can cause toxicosis in humans and animals. Some recent reports suggest that poisoning by the blister beetle has occurred in the Mediterranean part of Slovenia, which has never been reported before. Drought and modern harvesting techniques are thought to increase the likelihood of blister beetle forage contamination and cantharidin intoxication in animals. A survey of fields associated with blister beetle contamination was conducted and the Meloid species present were identified. Entomological surveillance was conducted for and . Cantharidin concentrations were also measured in both blister beetle species. Cantharidin concentration in ( = 17) ranged from 0.038 to 0.354 µg/mg (mean 0.151 µg/mg). Cantharidin concentration in ( = 36) ranged from 0.055 to 0.341 µg/mg (mean 0.142 µg/mg). Both species exhibited variable concentrations of cantharidin that could not be associated with their biology, sex, age, size, and/or reproductive status. have never previously been studied as a possible source of forage contamination, nor have cantharidin concentrations been determined in this species. It is the most likely source of forage contamination due to its abundance in the investigated fields, its swarming activity, and its tendency to reside in the green parts of plants immediately after cutting. Delaying the simultaneous processing and storage of forage after cutting would reduce the likelihood of forage contamination by blister beetles, as they can then retreat to the ground or fly away.
芫菁（芫菁属，芫菁科）会分泌斑蝥素，可导致人和动物中毒。最近的一些报告表明，斯洛文尼亚地中海地区发生了芫菁中毒事件，此前从未有过相关报道。干旱和现代收割技术被认为会增加动物食用被芫菁污染的草料以及斑蝥素中毒的可能性。对与芫菁污染相关的田地进行了调查，并鉴定了出现的芫菁种类。进行了为期[具体时长1]和[具体时长2]的昆虫学监测。还测量了两种芫菁体内的斑蝥素浓度。[物种1]（n = 17）体内的斑蝥素浓度范围为0.038至0.354微克/毫克（平均0.151微克/毫克）。[物种2]（n = 36）体内的斑蝥素浓度范围为0.055至0.341微克/毫克（平均0.142微克/毫克）。两种芫菁体内的斑蝥素浓度均呈现出变化，且与它们的生物学特性、性别、年龄、大小和/或繁殖状态无关。[物种1]此前从未被研究过是否可能是草料污染的来源，该物种体内的斑蝥素浓度也未被测定过。由于其在被调查田地中的数量众多、具有群聚活动，并且在收割后倾向于栖息在植物的绿色部分，所以它最有可能是草料污染的来源。收割后延迟草料的同步加工和储存将降低被芫菁污染的可能性，因为那时它们会退回地面或飞走。
