Eggs have gained a reputation as being a source of salmonellae. Given that some hens are exposed to salmonellae, it is important to determine what the risk might be to human health. White Leghorn hens were inoculated with Salmonella typhimurium, since this organism is often mentioned as being a common isolate from eggs and egg products. The hens were inoculated either orally or intravenously via the basalic vein of the wing. The oral inoculation of S. typhimurium did not result in contamination of the egg shells or contents (yolk and albumen) even though the organisms were eliminated with the feces. Intravenous injection did not lead to fecal shedding of salmonellae nor could the organism be isolated from the shell or the egg contents.
鸡蛋已被视为沙门氏菌的一个来源。鉴于一些母鸡会接触到沙门氏菌，确定其对人类健康可能存在的风险很重要。白来航鸡接种了鼠伤寒沙门氏菌，因为这种微生物常被提及是从鸡蛋和蛋制品中分离出的常见菌株。通过口服或经翅部尺静脉进行静脉注射对母鸡接种。即使这些微生物随粪便排出，口服接种鼠伤寒沙门氏菌也不会导致蛋壳或蛋内容物（蛋黄和蛋清）受到污染。静脉注射既不会导致沙门氏菌随粪便排出，也无法从蛋壳或蛋内容物中分离出该微生物。
