In order to provide consumers with trust in labeling, transparency, education, and other factors, If your product contains greater than 5% of ingredients that were bioengineered, product labeling must contain the appropriate mandatory labeling. This webinar will provide you and your staff with disclosure methods, implementation deadlines, labels, printed text, scanning information, web address, and text messaging designed to be sent directly to consumer mobile devices that disclose product GMO information. Food manufacturers are required to “prominently’ display clear label information regarding the presence of bioengineered ingredients. The new rules are designed to provide consumers with clear information and consistently labeled products. Understanding how the GMO Label Rules apply to your products is critical in order to avoid recalls.
