Field Contamination Patterns • Non-homogeneous distribution even with homogeneous contamination • Sporadic without detectable source • Directional because of known source

Current Industry Sampling Programs • Routine without cause (no apparent contamination risk factors) • Testing for-cause (because of a potential contamination risk) • Investigative sampling • Field sampling patterns • Sample size and collection • Sampling the whole plant vs. individual leaves • Limitations because of product perishability and inherent shelf-life limitations
