Leaving out things that one is unclear of

Q: Some one sends through WhatsApp messages saying chicken (in a Muslim country ) is not halal by forwarding some videos where we can actually see chicken getting processed by a machine. The authorities in the Muslim country are acknowledging that they are seeing it to that the things for the public are halal and not importing the haram chikcen and meat etc. One of my friends stopped eating chicken after seeing the WhatsApp.

My question is whom to believe? Do we have to believe the WhatsApp video or the authorities who are taking responsibility of halal produsts. If we believe WhatsApp then tomorrow other videos will declare meat as haram, please advise.
