Abstract

Sampling probe devices and methods for sampling frozen or solid meltable products are provided herein. Such devices can include a sampling probe with heating element and a cover fabricated at least partly from a microbial sampling medium that fits over the probe and heating element so that when the heated probe is placed against the frozen or solid product, the cover absorbs a liquid sample from the product. Methods of sampling include heating the probe and contacting the product with the cover until sufficient liquid sample is absorbed by the cover. The cover can be weighed after sampling and compared to a before-sampling weight to confirm sufficient liquid was obtained. The sample can be tested as an aggregate sample that is representative of the lot or batch of product being sampled, including testing without an enrichment procedure. Systems utilizing automated heated-sampling plates and radiative heaters are also described.
