12VAC5-421-1900: Hot water and chemical

After being cleaned, equipment food-contact surfaces and utensils shall be sanitized in:

1. Hot water manual operations by immersion for at least 30 seconds as specified under 12VAC5-421-1670;P

2. Hot water mechanical operations by being cycled through equipment that is set up as specified under 12VAC5-421-1610, 12VAC5-421-1680, and 12VAC5-421-1690 and achieving a utensil surface temperature of 160°F (71°C) as measured by an irreversible registering temperature indicator;P or

3. Chemical manual or mechanical operations, including the application of sanitizing chemicals by immersion, manual swabbing, brushing, or pressure spraying methods, using a solution as specified under 12VAC5-421-1700. Contact times shall be consistent with those on EPA-registered label use instructions by providing:

a. Except as specified under subdivision 3 b of this section, a contact time of at least 10 seconds for a chlorine solution specified under subdivision 1 of 12VAC5-421-1700;P

b. A contact time of at least 7 seconds for a chlorine solution of 50 mg/L that has a pH of 10 or less and a temperature of at least 100°F (38°C) or a pH of 8 or less and a temperature of at least 75°F (24°C);P

c. A contact time of at least 30 seconds for other chemical sanitizing solutions;P or

d. A contact time used in relationship with a combination of temperature, concentration, and pH that, when evaluated for efficacy, yields sanitization as defined in 12VAC5-421-10.P
