The aim of the study was to investigate the effects of formic acid addition to ground high risk animal by-products (ABP 1) in terms of stabilization and pathogen inactivation and to evaluate the biosecurity risk connected with the ABP 1 based combustion fuel Biomal. Laboratory studies were performed on the persistence of Salmonella Typhimurium, Bacillus cereus spores, porcine herpes virus, avian influenza virus, bovine viral diarrhea virus, equine rhinitis A virus and porcine parvovirus in Biomal at different storage times. It was shown that Salmonella and enveloped viruses were inactivated within 1 day (24 h). Bacillus cereus spores were not reduced during 147 days and the non-enveloped virus porcine parvovirus was still detected after 168 days of storage. The conclusion that can be drawn from the study is that transmission of some highly contagious diseases such as foot-and-mouth-disease, swine vesicular disease and egg drop syndrome, caused by non-enveloped viruses, may follow accidental leakages of Biomal. In addition, there is a risk of transmission of the diseases anthrax and black leg, caused by sporulating bacteria.
本研究旨在探讨甲酸添加到地面高风险动物副产品（ABP 1）中在稳定和病原体失活方面的作用，并评估与基于 ABP 1 的燃烧燃料 Biomal 相关的生物安全风险。在不同的储存时间内，对沙门氏菌 Typhimurium、蜡状芽孢杆菌孢子、猪疱疹病毒、禽流感病毒、牛病毒性腹泻病毒、马鼻炎 A 病毒和猪细小病毒在 Biomal 中的持久性进行了实验室研究。结果表明，沙门氏菌和包膜病毒在 1 天（24 小时）内被灭活。蜡状芽孢杆菌孢子在 147 天内没有减少，而非包膜病毒猪细小病毒在储存 168 天后仍被检测到。从研究中可以得出的结论是，由非包膜病毒引起的一些高传染性疾病，如口蹄疫、猪水疱病和产蛋下降综合征，可能会通过 Biomal 的意外泄漏传播。此外，由产芽孢细菌引起的炭疽病和坏疽病也存在传播风险。
