Salisbury's Trussell Trust says demand stripping supply
Managers at a Wiltshire-based foodbank say the service could be approaching "crisis point".
Staff at the Trussell Trust in Salisbury said food was going out faster than it was coming in despite people being very generous.
The foodbank, which depends on supermarket collections and donations, said this time of year was always tight but the problem was "accentuated".
The charity provides a minimum of three days emergency food for those in need.
"Last year we fed 600 people more than we did the year before so that another six tonnes of food that has gone out in the last 12 months," a foodbank spokesman said.
"That's bound to have an effect."
