Channel 4 aired an undercover report on Facebook's bad practices in monitoring harmful content last week.
The Minister for Communications has demanded 'significant measures' in moderation practices at Facebook.
Denis Naughten made the comments in a meeting with the social media giant in New York - days after the undercover report was aired by Channel 4.
An account from the meeting - reported by the Irish Independent - showed the Minister saying that he was 'appalled' by their procedures.
He said that changes needed to be made to ensure there was never a repeat of inappropriate content being allowed to remain on the site.
