Question

Bacteria die when they are refrigerated or frozen, true or false

Answer 1

The statement that "bacteria die when refrigerated or frozen" is false.

The correct statement can be written as "the division and multiplication of bacteria is hindered when refrigerated or frozen".

Further Explanation:

Bacteria's are known to survive in lower temperature. Refrigeration or freezing does hinder the process of division and multiplication of bacteria but does not cause death of the species. Thus, the bacteria still remain potent and may cause the infection.

The bacteria becomes dormant when subjected to colder temperature that is they become in active. This inactive form of the bacteria becomes active when subjected to a normal conditions.

This is totally different in the case of the heating that is increasing the temperature. This temperature increase helps in the killing the microbes thus aiding in the preservation or prevention from the bacteria.

Thus, to prevent growth of teh bacterial colony the process of freezing and refrigeration can be used but to kill the bacteria high temperatures are required.

Answer 2

Answer is "False".
 
For the growth of bacteria a certain temperature range is needed. Low temperatures slow down the growth of bacteria but cannot kill. But high temperatures can kill the bacteria. For the food safety the maximum temperature for the refrigerator should be 40 °F while 0 °F in freezer.
