  1. A field surveyor observes wild animal feces in a strawberry bed 3 days before scheduled harvest. According to GAP protocols, what is the APPROPRIATE response?

    Answer: Establish a buffer, conduct a visual inspection, and decide whether to harvest or destroy affected produce

    GAP requires establishing a buffer zone around contaminated areas, conducting a thorough visual inspection, and making a risk-based decision to harvest or destroy—never harvest without assessment.

  2. Which remote sensing technology is MOST commonly used in modern precision agriculture to identify within-field variability for survey purposes?

    Answer: Multispectral or NDVI imagery from drones or satellites

    Multispectral and NDVI (Normalized Difference Vegetation Index) imagery highlights plant health and stress variability across a field, guiding targeted ground surveys.

  3. Under the FDA Food Safety Modernization Act (FSMA) Produce Safety Rule, what is the required minimum number of water samples for an initial microbial survey of untreated surface water used for direct contact irrigation?

    Answer: 5 samples collected within the first 2-4 years

    FSMA requires a minimum of 5 samples to establish an initial water quality profile for untreated surface water used in direct-contact applications.

  4. A GAP field inspector is reviewing a grower's corrective action records. For which finding would a corrective action record be REQUIRED?

    Answer: Discovery of broken sanitation station during a pre-harvest inspection

    A non-functional sanitation station is a direct food safety deficiency that requires a documented corrective action, including the fix implemented and follow-up verification.

  5. When a field survey identifies that the calculated geometric mean of water test results exceeds the GAP action threshold, what does this SPECIFICALLY mean for the grower?

    Answer: The average contamination level over all samples exceeds the acceptable limit

    The geometric mean represents the average contamination level across all samples; exceeding the threshold means the overall water quality profile fails the standard.

  6. Which field survey data collection technique is MOST appropriate for mapping the spatial distribution of a foliar disease outbreak across a 200-acre field?

    Answer: Systematic grid walk with GPS-tagged disease incidence points

    A systematic grid walk with GPS-tagged incidence points produces a spatially accurate map of disease distribution, enabling targeted management across the entire field.

  7. In field survey documentation, what is the PURPOSE of recording the 'decision threshold' alongside pest count data?

    Answer: To provide context for whether the observed pest level triggered an action or was below threshold

    Recording the decision threshold alongside observed counts shows auditors that the grower assessed data against a standard and made an informed, justified decision.
