U.S. consumers’ processing of information about CRISPR-edited pork products

Abstract

ABSTRACT The commercialization of CRISPR gene-edited pork is advancing rapidly, following the U.S. Food and Drug Administration’s approval of gene-edited pigs resistant to Porcine Reproductive and Respiratory Syndrome (PRRS). As these products move closer to market entry, understanding how consumers seek, process, and avoid information about them is critical for developing effective communication strategies. Guided by the Risk Information Seeking and Processing (RISP) model, this study examined factors influencing information seeking, information avoidance, and information processing related to CRISPR-edited pork products among U.S. consumers (n = 2,006). Results show higher information sufficiency thresholds were associated with greater information seeking and lower information avoidance. Information seeking was strongly and positively correlated with systematic processing. Relevant channel beliefs and perceived information gathering capacities were positively associated across communication channels, suggesting the need for integrated communication approaches. Relevant channel beliefs for news media and social media were positively associated with information seeking, while stronger relevant channel beliefs for Extension were associated with lower information seeking. Respondents with some college education reported higher information seeking than those with only a high school diploma or GED, while older adults and individuals with higher education levels reported lower information avoidance. Results also showed that respondents exhibited high intentions to seek information and low tendencies to avoid information, suggesting openness to learning about CRISPR-edited pork. Participants also reported engaging more in systematic processing than heuristic processing, indicating a preference for careful and analytical evaluation of information. Findings highlight the importance of audience segmentation, multi-channel communication strategies, and evidence-based messaging to support informed public engagement with CRISPR-edited food technologies.
