【 摘 要 】
The observations on the protective effect of bacterial endotoxin in farm-derived cow’s milk on childhood asthma and allergy are contradictory. The aim of this study was to determine the endotoxin levels in ‘farm-derived whole raw’ and ‘processed shop’ sources of cow’s milk, and to test how the temperature and storing conditions might alter their endotoxin concentrations. Milk was collected from farms and shops. The level of endotoxin was measured by micro (gel-clot) Limulus amebocyte lysate test expressed as EU/ml. The concentration ranges of endotoxin were much higher and more widely scattered in the samples of whole raw farm milk than in the processed shop milk. Cold storage or heating increased the endotoxin concentrations in all samples of farm milk, but not in the processed shop milk. These results show that elevated levels of endotoxin in raw farm milk samples can occur from the cowshed or be formed during storage. In processed shop milk, storage does not cause any changes in the amount of endotoxin...
