New MicroCap Sampler Automates Pathogen Sampling on Cut Produce Processing Lines
MicroTally has commercially launched its MicroCap sampler, a process-integrated device designed to automate microbial sampling on cut and diced produce processing lines. According to MicroTally, the device provides continuous sampling across production lots without requiring the collection of product tissue.
Designed to fit over the dispersion cone of multi-head weighing scales, the MicroCap sampler grabs microorganisms from product surfaces as finished product passes through the weigh station. The device can operate unattended for up to two hours, which the company said can reduce the labor required for manual grab sampling.
MicroTally also said peer-reviewed research has demonstrated pathogen recovery equal to or greater than traditional manual grab sampling. The company said automated sampling can also reduce sampling labor, sample shipping weight, laboratory media use, and disposal costs.
Continuous, Non-Destructive Microbial Sampling
According to MicroTally, traditional grab sampling requires the collection of bulk product tissue, which can dilute microorganisms present on product surfaces and result in the loss of saleable product. The MicroCap sampler instead targets product surfaces, where the company said pathogen clusters on cut produce are more likely to occur.
The MicroCap sampler is constructed from sterile, nonwoven fabric and is available with 6-inch and 8-inch center-hole diameters to accommodate different scale dispersion cones. The sampler collects microorganisms through contact with product surfaces without damaging the product or generating waste.
Validated Applications for Cut Produce
The approach is designed to provide more representative samples for the detection of Salmonella, Shiga toxin-producing Escherichia coli, E. coli O157:H7, and Listeria, while preserving saleable product.
MicroTally said the MicroCap sampler is compatible with a range of cut produce products. Current validations include lettuce, cabbage, onions, carrots, tomatoes, and peppers.
