The 34-year-old took matters into his own hands as a chef trained in animal preparation when he caught, killed and cooked the creature.
The team had been surviving on a diet of rice and beans and were becoming increasingly concerned that if one of them was voted for a bushtucker trial, they would not have enough strength to complete it.
Discussing their rations and the prospect of eating the rodent, Stuart Manning said: "We need protein. We've got to get on with it and do it. If we're going to be fit and ready for the trials we've just got to do it, guys."
Once the rat was ready, Kim Woodburn refused to eat it, but eventually relented when both Lucy Benjamin and Sam Fox took a bite.
D'Acampo explained his behaviour in the Bush Telegraph, saying: "It's not done by choice but it's done because we need it. We need some kind of protein; we need some kind of flavour."
Despite their initial reluctance, all of the celebrities later agreed that the rat actually tasted rather good. "It was actually quite nice. We all said it was like chicken but chicken-y beef-y kind of stuff so it was actually very nice," George Hamilton stated. "If you kill it, you should eat it."
