the Food and Drug Administration require that
all cleaning and sanitizing solutions used with
food processing equipment be certified for this
use.
When sanitizing the freezer, refer to local sanitary regu-
lations for applicable codes and recommended sanitiz-
ing products and procedures. The frequency of sanitiz-
ing must comply with local health regulations. Mix sani-
tizer according to manufacturer’s instructions to provide
a 100 parts per million strength solution. Mix sanitizer in
quantities of no less than 2 gallons of 90°F to 110°F (32°C
to 43°C) water. Allow sanitizer to contact the surfaces to
be sanitized for 5 minutes. Any sanitizer must be used
only in accordance with the manufacturer’s instructions.
CAUTION
