What's more, beyond disappointing you gustatively as it falls onto the coals, the grease extracted from sausages can be dangerous for several reasons. First of all, you risk getting splashed with it, and at such a high temperature, it can cause a burn. To avoid this, be sure to adopt to barbecue safely. On the other hand, the grease couldfan the fire and cause flames. These flames will not only burn your meat, but also project soot residues onto it. These polycyclic aromatic hydrocarbons (PAHs), derived from coal, are particularly harmful to health as they are carcinogenic.
