(a) Commencing January 1, 2012, except as provided in subdivisions (b) and (c), a licensed child day care facility shall comply with all of the following requirements for beverages served by the day care provider to children in the provider's care:

(b) If a child has a medical necessity documented by a physician that includes the need for “medical food” as defined by Section 109971 of the Health and Safety Code, a licensed child day care facility shall be exempt from complying with the requirements of subdivision (a), to the extent necessary to meet the medical needs of that child.

(c) This section shall not apply to beverages at a licensed child day care facility that are provided by a parent or legal guardian for his or her child.

(d) As the Dietary Guidelines for Americans, published jointly by the federal Department of Health and Human Services and the federal Department of Agriculture, are updated every five years, the department may adapt the provisions of this section by bulletin, as necessary, so that the standards continue to reflect the most recent relevant nutrition science and continue to improve the health of children in child care.

(e) The department shall only determine compliance with this section during a regularly scheduled, authorized inspection, and shall not be required to conduct separate and independent visits.
