§ 915.18.

(A) The refrigeration system for an establishment shall be equipped with accurate and

reliable controls for the automatic maintenance of uniform temperatures as required

in the various refrigerated rooms and shall be of adequate capacity to provide under

extreme conditions of outside temperatures and under peak load conditions in the normal

operations of the establishment, the following temperatures: (1) In the chill room temperatures within two degrees of Fahrenheit plus or minus of

thirty-eight degrees above zero Fahrenheit with a tolerance of ten degrees Fahrenheit

for a reasonable time after fresh food is put in for chilling; (2) In the sharp freezing room temperatures of ten degrees below zero Fahrenheit or lower

or temperatures of zero degrees Fahrenheit or lower when forced air circulation is

employed with a tolerance of ten degrees Fahrenheit for either type of installation

for a reasonable time after fresh food is put in for freezing. (B) This section does not prohibit such variations as may occur during short periods

of time incidental to defrosting.  For experimental purposes, the department of agriculture, upon application in writing,

may authorize for a limited and prescribed period, the installation and use of refrigeration

systems or methods which in the opinion of the department will result in improvement

over present methods.
