据欧盟食品安全局（EFSA）消息，4月18日欧盟食品安全局就修订大米中三环唑（tricyclazole）的最大残留限量发布了意见。欧盟专家组经评估后认为，修订三环唑的数据不充分，因此仍维持现有1 mg/kg的最大残留限量。
部分原文报道如下：
In accordance with Article 6 of Regulation （EC） No 396/2005, Italy, herewith referred to as the evaluating Member State （EMS）， received an application from Dow AgroScience to set an import tolerance for tricyclazole in rice to accommodate the authorized use in Brazil. Tricyclazole is a non-included active substance and no EU uses are currently authorized. Thus, the existing EU MRL of 1 mg/kg in rice should be lowered to the LOQ. The applicant requested to maintain the existing EU MRL to allow the import of rice treated with tricyclazole from third countries. The EMS confirmed that the MRL should be set provisionally at the level 1 mg/kg to accommodate the Brazilian GAP.
EFSA is of the opinion that on the basis of the currently available studies, the toxicological reference values for tricyclazole cannot be set, since the genotoxic potential of tricyclazole could not be totally disregarded. In addition, uncertainties regarding the carcinogenic potential of tricyclazole were identified by EFSA. The submitted residue trials data were found to be insufficient to derive an MRL proposal which accommodates the use of tricyclazole on rice in Brazil. EFSA concludes that the import tolerance request for tricyclazole in rice is not sufficiently supported by data which would justify maintaining the existing EU MRL of 1 mg/kg in rice.
