Destruction of salmonellae in inoculated and naturally contaminated natural animal casings was studied. Salmonellae were effectively destroyed (99.999%) in inoculated hog casings after exposure for 24 h to saturated brine at pH 4.0 and 10.0 adjusted with acetic acid and sodium hydroxide, respectively. Treatment of inoculated hog and sheep casings in saturated brine or saturated brine with citric acid was not nearly as effective as brine containing acetic acid or sodium hydroxide. Salmonellae in naturally contaminated hog casings were virtually eliminated after 21 days of storage in crystalline sodium chloride. Salmonella in sheep and hog casings were eliminated after 7 days of storage in crystalline salt. Treatment of naturally contaminated hog casings with glycerin-salt or sorbitol-salt solutions was not as effective in destroying salmonellae as treatment with crystalline salt.
对接种和自然污染的天然动物肠衣中沙门氏菌的破坏情况进行了研究。分别用乙酸和氢氧化钠调节pH值至4.0和10.0的饱和盐水处理接种的猪肠衣24小时后，沙门氏菌被有效破坏（99.999%）。用饱和盐水或含柠檬酸的饱和盐水处理接种的猪和羊肠衣，其效果远不如含乙酸或氢氧化钠的盐水。天然污染的猪肠衣在结晶氯化钠中储存21天后，沙门氏菌几乎被消除。羊和猪肠衣在结晶盐中储存7天后，沙门氏菌被消除。用甘油盐或山梨醇盐溶液处理天然污染的猪肠衣，在破坏沙门氏菌方面不如用结晶盐处理有效。
