Microval approves renewal of Charm Sciences’ Peel Plate® EB certificate

In September 2026, MicroVal approved the renewal of the certificate for Charm Sciences’ Peel Plate® EB method. The renewal re-evaluated all existing claimed categories.

The method is validated for the enumeration of Enterobacteriaceae in 25 g test portions of heat processed milk and dairy products, infant formula, and infant cereal.

Q Laboratories conducted the validation study against the reference methods ISO 21528-1:2017 and ISO 21528-2:2017. The study was prepared in accordance with ISO 16140-2:2016, including Amendment 1:2024.

The renewed certificate, registered under study number 2017LR69, is available on the Issued certificates page, together with the supporting validation report.

Renewed certificate for Soleris Commercial Sterility Testing Vials (NF 105)

In June 2026, MicroVal approved the renewal of the certificate for Soleris Commercial Sterility Testing Vials (NF 105), manufactured by Neogen Corporation.

The original validation study was conducted in 2022 in accordance with ISO 16140-2:2016. As part of the renewal process, additional statistical analyses of the sensitivity study and interlaboratory study (ILS) were performed to meet the requirements of ISO 16140-2:2016+A1:2024.

Since the design of the sensitivity study remained unchanged between the two versions of the standard, the original data could be reanalysed using the updated statistical approach specified in ISO 16140-2:2016+A1:2024.

The renewed certificate, registered under study number 2021LR100, is available on the Issued certificates page, together with the supporting validation report.
