A game-changer in meat safety: MSD sampling method for E Coli
The FSIS has replaced the traditional N60 excision sampling method with a non-destructive technique utilizing a cloth-based Manual Sampling Device (MSD). Studies have shown that this innovative cloth sampling approach matches the effectiveness of the N60 method when it comes to detecting organisms in beef manufacturing trimmings.
A bonus is the added safety and speed – the cloth sampling procedure is quicker and minimizes risks associated with using hooks or knives, traditionally employed by FSIS inspection program personnel for sample collection. Furthermore, this non-destructive method ensures that no product is wasted during the sampling process, contributing to the reduction of food waste in the industry.

Out with the knives
In the world of beef processing, the "N60" and "N60 Plus" terms have long been associated with stringent sampling protocols for detecting Escherichia coli O157:H7 in beef trimmings. Implemented in 2003 and widely embraced by larger beef companies by 2007, these methods have earned their stripes as the gold standard in beef safety protocols.
As the wheel of progress turns, a revolutionary sampling method has emerged on the horizon. This new methodology employs a manual sampling device (MSD) – cloth swab to collect samples rather than extracting actual meat portions. This change brings several benefits to the table—it simplifies the sampling process, eliminates destructive testing, saves labor, and importantly, reduces waste.
In with the cloth
Incorporating this innovative method with common practices like post-enrichment pooling can deliver rapid, cost-efficient results, particularly when tested with PCR. Remarkably, mTSB-enriched surface swabs for beef trimmings have displayed an equivalent sensitivity to the USDA FSIS culture methods in the span of 8–10 hours.
Moreover, the MSD sampling methodology has demonstrated its prowess in detecting Salmonella, Shiga Toxin Producing E. coli (STEC), and other indicator organisms on beef trimmings. Supported by research data from the Agricultural Research Service (ARS), the MSD method matches, if not outperforms, the venerable N60 method and the IEH Plus Sampler in terms of pathogen detection.
The USDA FSIS has given the green light to the MSD sampling method, subject to certain operational parameters outlined in a 2017 document, "Protocols for Manual (MSD) Sampling Devices for Testing of Beef Trim". The stipulations include using both sides of the MSD, having a minimum sampling area of 140 square inches, among others.
Easy Collect: meat testing, well done!
Making the switch to the Easy Collect Fabric Samplers comes with a multitude of significant benefits.

Zero product waste:
with a cloth manual sampling device, actual meat portions are no longer necessary for testing. Instead, inspectors swab meat trim surfaces with Easy Collect, which means zero product waste.
Efficiency in sample collection:
the time it takes to gather samples is significantly reduced with the Easy Collect Fabric Sampler. This efficient method frees up crucial time in the production process, streamlining operations and enhancing productivity in your plant.
Improved safety for inspectors:
With the Easy Collect Fabric Sampler, inspectors no longer need to handle hooks or knives, which can pose significant safety risks.
All in all, the evolution from the conventional N60 sampling to the MSD methodology represents a significant leap forward in meat safety and efficiency, further ensuring the safety of raw products for consumers.
