The DUO coffee chain, which has branches in Tyumen, has commented for the first time on accusations of customer poisoning in Yekaterinburg. In our city, the establishments have been operating in a reduced format: salads, sandwiches, and main courses have been removed from the menu.

“The investigation by Rospotrebnadzor [the Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing] is not yet complete. The DUO chain and its suppliers are providing maximum assistance to the inspecting authorities — all necessary documents and products have been provided, all instructions and recommendations have been followed. The key point is that Rospotrebnadzor has no complaints against the chain itself or the coffee. At the moment, no violations have been found in product samples or in the health of workers,” said lawyer Georgy Krasnov.

The company clarified that DUO representatives have not been provided with a single medical document reliably confirming intestinal infections specifically from coffee consumption.

“On January 23, the Zheleznodorozhny District Court of Yekaterinburg will hold a hearing on suspending the activities of one of the suppliers to the DUO coffee chain — LLC ‘DESKOM+’ due to formal shortcomings in the layout of premises and production control. This supplier provides the coffee chain with a small volume of individual desserts. However, it did not produce ready-made food (salads, sandwiches). It is important that the investigation has not established a connection between the formal violations and the complaints received, and the supplier is not charged with such,” the lawyer noted.

Recall that DUO customers in Yekaterinburg began to complain en masse about poisonings in mid-January. City residents reported that after visiting the establishment they felt unwell: severe vomiting, weakness, chills.

After that, we visited a coffee shop in Tyumen and saw what had changed in the establishment’s operation. At the time, employees refused to comment on the reduction in the assortment.
