Abstract: Systems and methods for sampling within a conveyance system are provided herein, such systems and methods being particularly useful in batch sampling of food products for a targeted biological agent. In one aspect, the sampling system includes a conveyance system and one or more sampling devices positioned along a conveyance path such that at least one portion of the batch contacts a sampling medium of the one or more sampling devices. In another aspect, sampling devices are provided that allow a sampling member to be secured in a sampling position for batch testing and readily removed after sampling and tested. The systems, devices and methods herein provide improved sampling coverage of the entire batch and reduce waste and inefficiency as compared to conventional batch sampling methods.

Abstract: A sample holding device having a plurality of sample wells. A gutter surrounds the sample wells and is in fluidic communication with an overflow sample well. An upper surface of the device is sealed with a sealing film that fluidically isolates each sample well from each other and from the gutter and overflow well. The device is used to perform a most probable number (MPN) procedure.
