Abstract:Medicinal plants have been used for centuries as remedies against human diseases because they contain components of therapeutic value. Bee-Pollen was used for thousands of years as functional food and medicinal plant product. Various beneficial effects were attributed to it and its consumption was increased years. The positive effects of a functional food can be either maintaining a state of wellbeing and health or reducing the risk of pathologic consequences. Gastrointestinal functions, redox and antioxidant systems, and metabolism of macronutrients are the most promising targets for functional food science. Negative and undesirable side effects of food are important threads for human health, especially, unprocessed functional foods. In this work, sanitary microbiological analysis of unprocessed pollen collected from different Algerian regions was examined. Results obtained indicate that pollen obtained from Blida is more contaminated than samples obtained from SÚtif and Biskra. Total aerobic count was 3,0 ; 5,80 ; and 5,67 Log10 cfu/g for Blida, sÚtif and Biskra respectively. However, the occurrence of Staphylococcus aureus was observed only with pollen obtained from SÚtif region. Total coliforms count increases respectively with the increase of environmental humidity and temperature (3,0; 4,27 ; and 5,47 Log10 cfu/g for Biskra, sÚtif and Blida respectively). This phenomenon was also noticed for total moulds. From this primary microbiological analysis, consumption of unprocessed pollen can present a challenge for human and animal health, as it could be a carrier for numerous microorganisms, which may present a detrimental effects on body health.
