Last year more cruise ships failed health inspections than in the past decade.
The violations that can contribute to a failing grade include everything from a seemingly minor citation, such as a mop improperly stored, to conduct that could endanger passengers’ health, like where crew worked despite having symptoms of gastro illness.
Dr Marc Shaw, medical director of Worldwise joins Wendyl Nissen on The Long Lunch looking at ways to stay healthy on cruise ships.
He says more people are opting in for a holiday at sea.
There are significant numbers of people that are traveling overseas on cruise ships now.
"From New Zealand, over the last year, about 250,000 New Zealanders are traveling abroad overseas on cruise ships," Dr Shaw said.
"Mainly around the Pacific, as we know, and those are the ones that are tending to capture the limelight to a degree. But also around the Caribbean and up towards Alaska.
"There's a lot of excitement in going to these areas."
Dr Shaw says problems arise when large groups of people are stuck in a relatively small space, like a cruise ship, and outbreaks are likely.
"The potential infection is huge."
