Staff at Tesco Extra in Wisbech got their fingers dirty by holding a litter pick.
The group, including community champion Mallissa Russell, collected 22 bags within a few hours.
“We hope as a store to continue this each month to help our community,” she said.
Tesco Wisbech is holding a Rio carnival weekend in aid of Diabetes UK and the British Heart Foundation from August 11 to 13.
