Cruises are known for their luxury, from first class service to free meals throughout the holiday.
With free food comes a huge amount of waste, which many passengers may not realise.
Being so far out at sea, it can be hard to know what to do with the surplus meals.
It has since been revealed where it ends up going when it is left uneaten.
Anya Hoffman, who has worked in the cruise industry for fifteen years, revealed on Quora where the leftover food goes.
She wrote on the website: “Leftover food [is] what passengers don’t eat because they think they need to order all on the menu just for the sake of it.
“Food that has been prepared and served is put in the pulper, pureed, liquefied with water and discharged into the ocean when discharging is allowed.”
Whilst this may seem wasteful, a fellow cruise enthusiast explains the problems with giving the food to worthy causes.
Patricia Bothwell wrote: “It is problematic to donate food because of safe-handling concerns.”
Pullmantur Cruises goes into further detail: “Everything from gourmet steaks and luxurious chocolate desserts to leftover pizza crusts and vegetable peelings are all blended into a smooth solution, using an industrial blender.”
It isn’t the only secret to have emerged regarding what happens behind the scenes of a cruise holiday.
A cruise worker has explained that secret passages enable workers to get around the ship undetected.
Quora user James Abbgy explained: “There’s a network of corridors, elevators, stairs, etc. that are off limits to guests, that let us get pretty much anywhere unseen.”
Whilst this may sound creepy, it isn’t used to spy on the passengers on the ship.
With many cruise workers often working 12 hours days without a break, it means they can quickly traverse the ship without having to deal with passenger requests.
Cruise ships can be up to 1,000 feet, so it can be a long trip across the boat when part of the working crew.
Aggby admitted that they do keep tabs on passengers, albeit for different reasons.
He also stated: “We keep records on our guests. Nothing stalker-ish, but we keep track of who complains a lot, or big spenders in the casinos.”
