It probably is. There wouldn't be that many cases in a year in Ireland. I mentioned it here at the time but it was merged with another thread. I was a bit stunned that EU citizens were being trafficked into another EU country.
With reference to that Global Slavery Index, they're clearly a bona fide and reputable source of information who've conducted quite painstaking research, but there is a flaw in their methodology, in that they make certain extrapolations based on 'similar' countries, so for example, the slavery figures percentage wise of the population for Ireland and the UK are identical. Now they could well be making assumptions about Poland, based on a few of its neighbours where the trafficking thing is probably much worse.
