Quiz Show - TCS (temperature controlled for safety) or Shelf Stable? Buttercream Frosting

Updated: Jun 17, 2021

The term 'TCS' is often used to refer to food that either requires temperature or time control for food safety and 7 day date marking. So let the games begin and test your knowledge.

A chocolate cupcake with buttercream frosting.


This buttercream frosting was lab tested and did require refrigeration. There is always confusion when a lot of sugar is added to a product because sugar has the ability to inhibit microbial growth. Sugar basically dries out the food and with a low water activity level, it becomes shelf-stable. The recipe at this facility used showed there was still enough water in the frosting from the butter that could support microbial growth and required it to be treated as a TCS food. They have the cupcakes on a 4-hour time as control for public health agreement.
