Fig. 2. Effect of phage treatment and cold storage on L. monocytogenes levels in various foods (A) Apples. Experimentally contaminated apple slices were treated with water, AS only,
ListShield™ diluted with water, or a combination of ListShield™ diluted with AS. Limit of detection 6 CFU/g. Error bars represent standard error of the mean (SEM) (n ¼ 3).
*p < 0.05; (B) Cheese. Experimentally contaminated cheese was treated with PBS (white bars) or ListShield™ (gray bars). Limit of detection 18 CFU/g. Error bars represent standard
error of the mean (SEM) (n ¼ 3). ***p < 0.001.
