据欧盟食品安全局（EFSA）消息，应欧委会的要求，11月13日欧盟食品安全局就毛蛋作为生产沼气与肥料的原料时，所采用的加工方法对人与动物健康的风险进行了评估。
专家组经评估发现，肉毒杆菌是毛蛋加工过程中最为顽固的病菌。圆环病毒、细小病毒、屎肠球菌被认为是最耐热的病毒与非产孢菌。专家组评估了加工方法对抗这些危害因素的功效。评估发现，沙门氏菌与禽流感病毒等热敏感物质经过加工后基本上不会存活，然而其他耐热菌与病毒不能很好的灭活。

In 2011, EFSA assessed the risk posed by the possible use of dead-in-shell chicks for the production of processed pet food. In 2014, the European Commission asked for an updat on the risk posed by the same material but as raw material for the production of biogas and compost according to standard transformation parameters normally used for Category 3 material. According to current European unio legislation, the following processing method was considered: maximum particle size before entering the processing unit: 12 mm; minimum temperature in all material in the unit: 70°C; and minimum time in the unit without interruption: 60 minutes.
