Comparison of Alternative Wetting Agents for Drag and Bootie Swabs for Agricultural Soil Sampling

Abstract Drag and bootie swabs have been used in animal (e.g., poultry litter) and produce (e.g., soil) production for food safety purposes in place of grabs. Skim milk, the industry standard wetting agent for drags and booties, is not ideal for produce soil sampling due to its allergenic properties and animal-based origin, and (depending on […]

A Validated Preharvest Sampling Simulation Shows that Sampling Plans with a Larger Number of Randomly Located Samples Perform Better than Typical Sampling Plans in Detecting Representative Point-Source and Widespread Hazards in Leafy Green Fields

Abstract Commercial leafy greens customers often require a negative preharvest pathogen test, typically by compositing 60 produce sample grabs of 150 to 375 g total mass from lots of various acreages. This study developed a preharvest sampling Monte Carlo simulation, validated it against literature and experimental trials, and used it to suggest improvements to sampling […]
