Internal investigations ongoing: iJooz
In response to Mothership's queries, iJooz said it takes a serious view of the alleged incident and has initiated an internal investigation.
The incident "concerns the hygiene and safety standards that we are fully committed to upholding," the company said, adding that it has escalated the matter to the relevant authorities and filed a police report.
iJooz also stated that it is accelerating the rollout of upgraded machines across Singapore to enhance hygiene safeguards.
"Some of our newer machines are already equipped with enclosed systems, where straws are not exposed prior to dispensing under normal operation," it said.
The company added that it intends to expand these features islandwide to reduce the risk of similar incidents.
