An investigation was conducted to test the hypothesis that the storage time of packaging sterility has no effect on contamination susceptibility even under deliberate bacterial exposure (Serratia marcescens). No growth of the test microorganisms was identified in the experimental group in any of the storage intervals (7, 14, 28, 90, and 180 days). Current recommendations/guidelines suggest that contamination of packaging occurs only because of events. This study, done in vitro, supports these recommendations.
进行了一项调查，以检验以下假设：即使在故意细菌暴露（粘质沙雷氏菌）的情况下，包装无菌的储存时间也不会对污染易感性产生影响。在任何储存间隔（7、14、28、90 和 180 天）中，实验组中均未发现试验微生物的生长。目前的建议/指南表明，包装污染仅因事件而发生。这项体外研究支持这些建议。
