Friends, Long time I specualte about the possibility of health risk caused by Ascosphaera apis spores which must be contained in honey taken from colonies suffering chalk brood. The danger may be even more serious when from such colonies pollen is collected and when among polen grains parts of mummies often occur. Pollen often is considered as a quality food supplement for people, too. Is there any knowledge in this field?
