Older adults are susceptible to and at greater risk for food-borne illness in comparison to those in other adult age groups. Online education is an underused method for the delivery of food safety information to this population. Three online mini-modules, based on social marketing theory (SMT), were created for and pilot-tested with older adults. These mini-modules were effective in promoting familiarity with food safety behaviors and were well-received, supporting the development of future SMT-based online education for this target audience.
