During this outbreak, a first peak could not be comp letely investigated and was followed by a second peak when the contami nated food was given again. S. enterica ser. Heidelberg and S. enteric a ser. Manhattan were isolated from patient stool samples, The case co ntrol survey indicated asparagus or bacon as contamination source. Mic robiological analysis of food confirmed bacon contamination, probably consecutive to insufficient pickling.
