What information would be most relevant to determining the time of death?
Nuetrik [128]

Lividity can be defined as the typical bluish-purple discoloration of the skin after death. Rigor mortis can be defined as the postmortem state in which the muscles become stiff.

  • After death, the stomach contains identifiable ingested foods within two hours.

  • Rigor mortis is characterized by the stiffening of the body after death, which is caused by the absence of ATP in muscle tissues.

  • Postmortem lividity or livor mortis is caused by the accumulation of blood in blood vessels (the lack of arterial pressure) as a result of gravity.

  • The most relevant information to determine the time of death is the presence of lividity, rigor mortis, and/or stomach contents (Option c).

A food handler does not need to worry about time and temperature
alukav5142 [94]
This statement is inaccurate because food handlers need to prepare food at the quickest rate possible. This is to prevent spoilage from happening because the changes in temperature in which the food is exposed has something to do with the development of certain kinds of bacteria that can be harmful to a person's health.
