(CNN) — Police in Germany are investigating after sandwiches left on the doorstep of a company labeled as a “present” turned out to be spiked with rat or mouse poison.

About 25 workers at the company in the town of Steinfeld, Lower Saxony, helped themselves to the filled bread rolls Tuesday after they were left in a box that said they were to be eaten, police in nearby Cloppenburg said.

Later that afternoon, an alarm was raised when a strange substance was noticed atop the bread rolls, the police statement said.

The discovery prompted 11 people to admit themselves to local hospitals, but no one has yet shown any symptoms as a result of eating the bread rolls, police said.

The substance was flown to a Berlin hospital for tests that confirmed it was rat or mouse poison.

The strength of the poison is not yet known, police said.
