Can food products from Muslim small businesses without the JAKIM halal logo be considered halal, and should they be preferred over non-Muslim products that carry the logo?

Summary

Muslim small-industry products without the JAKIM halal logo cannot be regarded as non-halal or haram, since halal status depends on the ingredients used and preparation methods that comply with Islamic law. Such products are considered halal if one is confident they are free from prohibited elements, but should be avoided if there is doubt or the preparation is affected by impurities. Muslim producers are encouraged to apply for halal certification, and Muslim consumers are urged to support fellow Muslims by buying their products where a choice exists.
