MicroTally Launches MicroCap Sampler to Automate Pathogen Sampling for Cut Produce Processing Lines

SAN JOSE, Calif. — MicroTally®, a leader in advanced food safety sampling technology, announced the commercial release of the MicroTally® MicroCap™ sampler, an automated, process-integrated sampling device designed for cut and diced produce operations.

Designed to fit over the dispersion cone of multihead weighing scales, the MicroCap™ sampler captures representative samples of contaminating microorganisms as finished product passes through the weigh station. The device operates unattended for up to two hours across large production runs, eliminating manual grab sampling and reducing labor requirements.

“Traditional manual grab sampling relies on collecting bulk product tissue, which can dilute surface-level pathogens and create unnecessary food waste. Because contamination on cut produce predominantly resides on exterior surfaces, the MicroCap™ sampler targets the areas where pathogen clusters are most likely to occur. This approach can provide processing plants with more representative samples for detecting Salmonella, STEC, E. coli O157 and Listeria while preserving saleable product.”

Key Features and Benefits

The MicroTally® MicroCap™ sampler offers the following features and benefits:

• Automated Lot-Wide Sampling: Operates continuously for up to two hours on active processing lines, replacing spot-check grabs with continuous batch coverage.
• Non-Destructive Surface Capture: Collects microbial samples through surface contact without damaging product or generating waste.
• Reduced Dilution Risk: Focuses on surfaces where pathogen clusters are most likely to occur.
• Peer-Reviewed Performance: Peer-reviewed research has demonstrated pathogen recovery equal to or greater than that of traditional manual grab-sampling methods.
• Operational Savings: Streamlines sampling labor, reduces shipping weight for testing samples, and lowers laboratory media and disposal costs.
• Seamless Line Integration: Made from sterile, nonwoven fabric and available with 6-inch and 8-inch center-hole diameters to fit a variety of scale dispersion cones.

The MicroTally® MicroCap™ sampler is compatible with a range of cut produce. Current validations include lettuce, cabbage, onions, carrots, tomatoes and peppers.
