Mich. Comp. Laws § 289.8103: Bulk displays of unpackaged food and drink; salad bar; sign requirements; placard.

Sec. 8103.

All bulk displays of unpackaged food and drink offered for sale at a retail food establishment, including salad bars, which contain a detectable amount of sulfiting agents shall be prominently placarded with a sign which is clearly visible to the customer and which declares either of the following statements:

( NAME OF PRODUCT )

THIS PRODUCT CONTAINS A SULFITING AGENT. SULFITES MAY CAUSE AN ALLERGIC REACTION IN CERTAIN PERSONS, PARTICULARLY ASTHMATICS.

( NAME OF PRODUCT ) _______________, the blank to be filled in with the name of the sulfiting agent, and if added as a preservative, a separate description of its function.

All letters on the sign shall be of the same type style and color, not less than 1/4 inch in height, and of a color in clear contrast to the background. A smaller type size may be permitted if the department determines space is not available for the placard and the largest type size possible is used. If a retail establishment has multiple bins of sulfite-treated food which are segregated, 1 placard listing all of the applicable products is acceptable if it is placed at approximately eye level over the bins.
