Therapeutic and Safety Evidence for Bee Pollen and Related Pollen-Derived Products: A Systematic Review with a Focused Meta-Analysis of Bee Venom-Related Systemic Allergic Reactions in Beekeepers

Abstract

Bee pollen consumption and bee venom exposure during beekeeping are distinct in their routes of exposure and clinical outcomes but are relevant to a common safety framework. This systematic review primarily examines safety findings related to the consumption of bee pollen and pollen-derived products and occupational allergic outcomes among beekeepers; therapeutic findings in humans are considered a secondary and complementary area of evidence. The quantitative synthesis was restricted to lifetime self-reported systemic allergic reactions (SAR) to bee venom among beekeepers. A lifetime self-reported SAR was defined as a participant-reported history of systemic symptoms following a bee sting at any time before study participation. PubMed/MEDLINE, Scopus, and the Web of Science Core Collection were searched without language restrictions from inception to June 10, 2026, and the reference lists of relevant studies were manually reviewed. Of 2107 records identified, 886 duplicates were removed, 1221 titles and abstracts were screened, 222 full-text reports were assessed for eligibility, and 149 studies were included in the qualitative synthesis. Six observational studies providing usable lifetime self-reported SAR data were included in the meta-analysis (N=2826; 399 cases). The corrected pooled random-effects estimate was 14.2% (conventional 95% CI: 7.1–26.3%; Hartung–Knapp 95% CI: 5.5–32.2%), with extreme between-study heterogeneity (I²=97.6%; τ²=0.89) and a wide 95% prediction interval (1.0–73.9%). Excluding the study rated at high risk of bias, which had an approximately 3% response rate, increased the pooled estimate to 17.8% (95% CI: 10.4–28.7%), while heterogeneity remained extreme (I²=95.4%). These findings indicate that the pooled estimate should be interpreted as a summary of heterogeneous survey-based findings rather than as a prevalence estimate directly transferable across countries or beekeeping settings. Human evidence concerning the therapeutic effects of bee pollen remains limited, heterogeneous, and dependent on product characteristics. Anaphylaxis and eosinophilic gastrointestinal disorders in susceptible individuals represent clinically important safety signals. The findings support clearer product identification, botanical and allergen labelling, and systematic adverse-event reporting for bee pollen products, together with strengthened risk assessment, worker training, protective measures, and emergency preparedness in beekeeping.
