I found some new idea regarding halal meat in the web site www.quran-islam.org
Is this web page is authentic Islamic or fake?
I read the article on Halal meat referenced in your question and I completely disagree with the article. I believe the article is completely wrong and completely out of live from Islamic teachings on the subject of Halal meat.
In order for the meat to be consumed by a Muslim, there has to be two things: 1) First the meat has to be of a Halal animal such as goat, cow, sheep etc... 2) Secondly, the animal has to be slauhgtered by a Muslim or a follower of a divine scripture. If any of these two conditions are missing then the meat will not be considered Halal.
And Allah knows best.
