What is the minimum recommended dehydrator temperature when making jerky?

A. 212º F B. 140º F

C. 145º F D. 160º F

What is the minimum recommended dehydrator temperature when making jerky?

C. 145 FResearch published by the University

of Wisconsin-Madison recommends that meat be dried at 145ºF or above.

Precooking jerky in a marinade to 160°F is done to:

A. To kill pathogenic bacteria.B. Because most home dehydrators are

not designed to reach high temperature.

C. Precooking in marinade shortens the drying time and makes a tender jerky.

• Precooking in marinade does shortens the drying time and makes a tender jerky however the main reason is the following:

• E. coli 0157:H7 bacteria can grow in the intestines of animals and contaminate meat during handling. To kill these bacteria, jerky must be heated to 160°F while it is still moist.

• Because most home dehydrators are not designed to reach this temperature, the jerky must be heated in another way to guarantee safety.
