Brown Rot Management in a Wet Growing Season: Part I

Mid-July has arrived and the 2015 peach harvest season has begun in earnest. As each successive crop of fruit mature and ripen, they become susceptible to infection by the brown rot fungal pathogen, Monilinia fructicola. Since spores of this pathogen require water to germinate, the number of fruit infection periods and therefore severity of the 2015 epidemic will be very much dependent on the number of rainfalls.

Audit Ready: Heads Up on Handwashing Stations, Well Water Sampling, & Traceability

Handwashing Stations

Auditors have noted that on handwashing stations some have a label which says “Not potable water.” If a grower is doing the USDA GAP or Harmonized audits, the water in handwashing stations must meet the “Microbial standard for drinking water.” If a label is on the wash station marked not potable, the grower is not in compliance. Check G-9 in the GAP or 2.2.5 in the Field Operations and Harvesting Harmonized Food Safety Standard for more details.

From Grower Self Audit for USDA GAP Audit General Questions G-1 to G-15:
G-9. All toilet/restroom facilities are clean and properly supplied with single use towels, toilet paper, and hand soap or anti-bacterial soap and potable water for hand washing.
