Sampling Plan Update
Current Situation:
Fields will not be sterile
Industry data: leafy greens field operating under GAPs will still have
about 0.2% frequency of detectable pathogens in field
Sampling to prove “pathogen-free” is impractical

Sampling Plan Update
Objective:
Evaluate existing sampling protocols (industry, FDA “site-specific risk-
b d
h”)
ase approac
Identify/recommend/develop a field sampling protocol, e.g.,
For routine sampling (e.g., to meet a customer requirement)
For cause or investigative sampling (e.g., if a potential food safety issue is
identified)
Directional/gradient sampling (e.g., from least likely to most likely areas)
Define a sampling lot, while considering field assessments and historical data
Determine what level of statistical confidence can be achieved
