Is Embalming Reguired?
Embalming requirements vary from state to state. Some states do require it for all deceased bodies. Some require it if there is going to be a viewing period of more than a specified period of time, for example 36 hours. Some mausoleums require all bodies entombed in above-ground crypts be embalmed. Some religious faiths do not allow embalming (ex. Judaism, Muslim). If the body will not be buried within a day after death, many states require the body be refrigerated until it is transported to the cemetery or other final place of rest or cremation.
NOTE: contrary to popular idea, embalming does not provide perfect, perpetual preservation. It merely slows the decomposition process. All bodies will eventually decompose to some degree. Depending on conditions in the grounds, they may more mummify than decompose.
