Various sugar products were examined for contamination with C. botulinum spores. Type A, B and C spores were detected in three of 56 samples of sugar for apiculture, which may attest the significance of bee-feed as a source of contamination of honey. The heavy contamination of honey with C. botulinum spores sometimes encountered, however, can not be explained unless some other factors, e.g., that allowing germination and multiplication of the spores somewhere during honey production, are found. Type A spores were detected in some samples of raw sugar and molasses and also in two of 41 samples of brown sugar lump, but not in refined sugar or other various samples taken at a sugar factory or in sugar cane left on the field in Okinawa. The fact that some natural sweetenings are contaminated with C. botulinum spores, even in low concentrations, may be food-hygienically important.
对各种糖产品进行了肉毒梭菌孢子污染检测。在56份养蜂用糖样品中的3份中检测到了A、B和C型孢子，这可能证明蜜蜂饲料作为蜂蜜污染源的重要性。然而，有时遇到的蜂蜜被肉毒梭菌孢子严重污染的情况，除非发现其他一些因素，例如在蜂蜜生产过程中的某个地方允许孢子发芽和繁殖的因素，否则无法解释。在一些原糖和糖蜜样品中检测到了A型孢子，在41份红糖块样品中的2份中也检测到了A型孢子，但在精制糖或在糖厂采集的其他各种样品中，以及在冲绳田间的甘蔗中均未检测到。即使某些天然甜味剂被肉毒梭菌孢子污染的浓度很低，这一事实在食品卫生方面也可能很重要。
