The FDA Produce Safety Rule (21 CFR 112) governs growing, harvesting, packing, and holding of produce for human consumption. It is the federal foundation under FSMA for produce operations and it expects documented controls on equipment, water, sanitation, and worker hygiene. For Tampa Bay grower-shippers, the cold-side and water-side requirements are the parts most likely to surface in an inspection — and the parts most operators have not fully documented.
21 CFR 112 covers produce that is normally consumed raw, with carve-outs for produce destined for commercial processing with kill steps. Operations selling under the qualified-exemption threshold ($25,000 to ~$571,000 in 2026 dollars, indexed) have reduced documentation but still must meet sanitation and water requirements. Operations above the threshold are fully covered.
Sprouts have their own Subpart M with stricter requirements. Tampa Bay sprout operations should reference Subpart M directly, not the general rule.
Subpart K is where most of the cold-storage expectations sit. The rule requires that holding activities not contaminate produce with biological hazards and that equipment be designed, constructed, installed, and maintained to prevent contamination. In practice this means walk-in coolers, hydrocoolers, and packing-line equipment need documented cleaning and sanitation procedures, not just temperature monitoring.
The rule does not specify temperature setpoints or continuous monitoring. It expects that whatever cooling step you operate is adequate for the produce, validated, and documented. An inspector asking "how do you know your post-harvest cooler holds 38°F?" expects an answer with records, not opinion.
Subpart L expects food-contact and produce-contact surfaces to be cleanable, in good repair, and sanitized on a documented schedule. For cold-side equipment, this includes evaporator drain pans, walk-in floors, hydrocooler basins, and conveyor belts.
Cooler walls and ceilings are not "produce contact" but condensate dripping from a fouled evaporator into product is. A drain pan stuck flooded is a Subpart L issue, not just a refrigeration issue. Document evaporator pan inspection on the cleaning log.
Water used in covered activities — including hydrocooling — must be from an approved source, tested at documented frequency, and treated as needed to manage cross-contamination risk. The rule's water-quality numerical standards have shifted across rulemakings; the current expectation as of 2026 is documented testing on a risk-based schedule with corrective action when exceedances are found.
For a hydrocooler running municipal Tampa Bay city water, the source qualifies; testing of the recirculated water and antimicrobial dosing (chlorine, peroxyacetic acid, or chlorine dioxide) is the operator's responsibility. Document dosing concentration, contact time, and ORP readings.
Records must be original, contemporaneous, dated, signed (or initialed) by the person performing the activity, and kept for two years. Continuous temperature logs from ColdSentry or equivalent meet this when paired with a written corrective-action procedure for excursions.
The single most common finding we see in mock inspections is a temperature log without corrective-action notes. The cooler drifted to 41°F at 2:47 AM, recovered by 4:15 AM, and there is no record of who saw the alarm and what they did. Build the corrective-action capture into the SOP.
FDA conducts Produce Safety Rule inspections through state contracts — in Florida, FDACS Bureau of Food Safety conducts inspections under federal authority. An FDACS inspector arriving for a PSR audit looks at records first, walks the operation second, and pulls water and produce samples third. Records are the differentiator.
If a cooler's evaporator condensate drip-tested into a pallet of greens, the immediate corrective action is to discard or divert affected product, document the event, and repair the equipment. The longer-term corrective action is a design fix — drain extension, pallet placement SOP, or evaporator relocation.
Document both layers. An inspector reviewing a recurring drip event with only immediate corrective actions, and no design fix, sees an uncontrolled hazard.
Continuous probes (ColdSentry or equivalent) on every cold-storage room and every hydrocooler. Written sanitation SOPs for cold-side equipment with frequency based on use. Documented water testing per the operation's commodity risk profile. Records retained two years, exportable on request. Annual mock audit — the cheapest insurance against a finding.
The rule does not specify continuous monitoring as a method. It requires that holding equipment be adequate to prevent contamination and that records demonstrate control. Continuous monitoring is the practical standard inspectors expect post-FSMA 204; spot temperature checks alone are increasingly seen as inadequate documentation.
FDACS Bureau of Food Safety conducts PSR inspections in Florida under contract with FDA. The bureau also handles FDACS-specific food-distribution and packing rules. An inspection is typically a single visit covering both authorities.
Equipment design and installation records, cleaning and sanitation logs, temperature monitoring records with corrective actions, and water testing records (where applicable). Two-year retention. Records must be original, dated, and identified to the person performing the activity.
No. The Produce Safety Rule covers produce normally consumed raw by humans. Cut flowers and ornamental floral are not covered. Floral wholesale operates under FDACS Bureau of Food Distribution rules and PACA cold-chain expectations, not 21 CFR 112.
Suncoast Cold Systems services floral and agricultural refrigeration across Tampa, St. Petersburg, Clearwater, Brandon, Riverview, Temple Terrace, and Wesley Chapel — retail floral display coolers, wholesale floral DC walk-ins, ag packing-shed cold rooms, hydrocoolers, and forced-air cooling tunnels. 24/7 dispatch.
