A three-tier breakdown of Open, Restricted, and Prohibited food categories for home food sellers in Puerto Rico — with plain-English explanations of why each rule exists.
The distinctions between Open, Restricted, and Prohibited products aren't arbitrary — they reflect decades of food safety science. The central question regulators ask about any food is: could this product make someone sick if the producer makes a mistake? The answer determines how much oversight applies.
TCS foods — those requiring Time/Temperature Control for Safety — are the core of food regulation. These are products where harmful bacteria can multiply to dangerous levels if not kept cold (below 41°F) or hot (above 135°F). Dairy, meats, cooked vegetables, and anything with high moisture and low acid content are all TCS foods. A jar of strawberry jam with 60% sugar sits in a fundamentally different risk category than a cream-filled pastry.
Two numbers determine whether a food is shelf-stable: pH (acidity) and water activity (aw). Foods with pH at or below 4.6 are too acidic for most pathogens to thrive. Foods with aw at or below 0.85 are too dry. Products that hit both thresholds are generally non-TCS and appropriate for home production. Your jams, properly made, achieve this naturally through sugar concentration and natural fruit acids.
Puerto Rico's tropical climate creates additional considerations for food safety. Warm ambient temperatures can accelerate bacterial growth on products that might be stable in cooler climates. This makes proper packaging, sealing, and storage even more important for home food sellers on the island. When in doubt, verify the shelf-stability of your specific product with the Department of Health before selling.
