Five-hundred participants answered the screeningquestionnaire. Among all participants, nine (1.8%) participants claimed to have experienced adverse reactions to pork previously. Among 100 participants who underwent blood sampling, five (5%) participants had elevated level of serumIgE specific to pork. However, among nine participants with self-reported porkallergy, two participants (0.22%) showed a positive reaction on the open OFC test.
CONCLUSION:
Some participants claimed to have a history of adverse reaction related to pork intake; however, few of them showed positive results in allergy tests. We therefore conclude that the prevalence of porkallergy is extremely low in Korea.
