Notes
Data entered reflect RCARDs with expiration date of 08/08/25, which are from the lot I've been using this year.
I also tested with new RCARDs with an expiration date of 03/18/26. The results from these cards: 0 E. Coli with 'other coliforms' 2000, 2500, and 2900.
All RCARDs were reviewed and colonies counted within 25 hours, and cards were re-reviewed the next day to determine whether the elapsed time made any difference in color, size, or frequency of coliform results. Aside from the original count difference, there is no discernible difference in any of the other variables between the RCARDs; therefore, I plan to continue using the older cards until the supply is extinguished.
