“Tissue gas was an embalmer’s worst nightmare - a highly infectious form of bacteria that thrived on dead tissue and released a noxious gas inside the body. Smell was usually the easiest way to detect it, but sometimes, as with this body, the smell was buried under other chemicals, and the only way to identify it was the ‘skin-slip’ Mom had found on the back, where interior gas bubbles separated the skin from the muscle. The gas itself was bad enough, because the stink would soon become so foul it would be all but impossible to cover up; that didn’t reflect well on us when people showed up for the viewing. Even worse than the gas though, were the bacteria that made it. Once they got into your workspace, you might never get them out again. If we didn’t put a stop to this right now, every body we embalmed would catch the same bacteria from our tools and table. It could destroy the entire business.”
