(19)Sodium silver thiosulfate was approved by Commission Implementing Regulation (EU) No 1195/2013note, which provides that only indoor uses in non-edible crops may be authorised for that substance. The conditions of use of that substance are not expected to lead to the presence of residues in food or feed commodities that may pose a risk to the consumer. Additionally, residues of silver from the use of sodium silver thiosulfate cannot be distinguished from residues resulting from the presence of silver in the environment, which occurs at higher levels. Moreover, thiosulfate degrades rapidly in the environment to substances that are also naturally occurring. Given that the Authority did not identify any concerns related to the properties of the substancenote, it is appropriate to include sodium silver thiosulfate in Annex IV to Regulation (EC) No 396/2005.
