The authors evaluated the effectiveness of adhesive mats, contamination control flooring, and shoe covers in decreasing the presence of microbial agents on animal holding room floors and footwear. Swab samples taken from animal holding room floors after the use of each product were compared with samples taken from rooms after no products were used. Swab samples were also taken from the heels and soles of the footwear of animal care staff before and after use of each product. The use of contamination control flooring or shoe covers significantly reduced the amount of organic material (as indicated by ATP levels measured by a luminometer) present on floors. Bacterial and ATP contamination of footwear was significantly lower after the use of shoe covers than after the use of adhesive mats or contamination control flooring, and the use of shoe covers led to a greater decrease in contamination before and after use than did use of either of the other two products. Although shoe covers were superior to both adhesive mats and contamination control flooring for decreasing contamination of animal room floors and footwear, facilities must take into account the contamination control standards required, the cost of the product, and the labor and time associated with product use when deciding which contamination control practices to implement.
作者评估了粘性垫、污染控制地板和鞋套在减少动物饲养室地板和鞋上微生物存在的有效性。在使用每种产品后，从动物饲养室地板上采集的拭子样本与未使用产品的房间进行了比较。在使用每种产品前后，还从动物护理人员的鞋子的脚跟和鞋底采集了拭子样本。使用污染控制地板或鞋套可显著减少地板上存在的有机物质（通过光度计测量的 ATP 水平指示）。与使用粘性垫或污染控制地板相比，使用鞋套后，鞋子上的细菌和 ATP 污染明显降低，使用鞋套可在使用前后显著减少污染，而使用其他两种产品则不行。尽管鞋套在减少动物室地板和鞋的污染方面优于粘性垫和污染控制地板，但设施在决定实施哪种污染控制措施时，必须考虑到所需的污染控制标准、产品的成本以及与产品使用相关的劳动力和时间。
