An operation uses an iodine sanitizer in its third sink. Which set of conditions does the Food Code require?
a.At least 55°F, with a pH of 7.0 or less
b.At least 68°F, with a pH of 5.0 or less
c.At least 75°F, with a pH of 8.0 or less
d.At least 100°F, with a pH of 10.0 or less
Explanation
An iodine solution needs a minimum temperature of 68°F, a pH of 5.0 or less, and a concentration between 12.5 and 25 mg/L. The 75°F and 100°F figures belong to quaternary ammonium and chlorine, and iodine loses effectiveness as the solution grows less acidic.
