Kelaguen, tinaktak, kadu — CHamoru prepared dishes are some of the island's most beloved foods. Here's what home sellers need to know about making and selling prepared meals safely and legally in Guam.
TCS stands for Temperature Control for Safety. These are foods that can support the rapid growth of harmful bacteria — including Salmonella, E. coli, Listeria, and Staphylococcus aureus — when held in the wrong temperature range for too long. The Guam Food Code (Title 26 GAR, Division 1, Chapter 4, Article 4A) requires TCS foods to be held at safe temperatures at all times, from production through point of sale.
Unlike shelf-stable foods, TCS foods cannot simply be packaged and left at room temperature. They require active temperature management — either kept hot above 135°F or kept cold below 41°F — with no more than 4 cumulative hours in the danger zone between those temperatures.
Bacteria double every 20 minutes inside this range. A prepared meal left at room temperature — even Guam's typical 85°F — can reach unsafe bacterial counts within 2–4 hours. This is why TCS foods sold at markets or for delivery require cold-holding equipment and clear buyer handling guidance.
Common TCS foods include: all cooked meats, poultry, and seafood; cooked rice, beans, and pasta; dishes with eggs; dairy-containing preparations (cream sauces, custards); cut melons and tomatoes; raw seed sprouts; and anything with a water activity above 0.85 and pH above 4.6. Most traditional CHamoru prepared dishes — including kelaguen, red rice, kadu, tinaktak, and escabeche — are TCS foods.
Because Guam has no cottage food exemption, home food sellers who hold a Home Industry license and DPHSS Sanitary Permit are treated as licensed food establishments — and that actually opens more doors for prepared meal sellers than a typical cottage food exemption would. Most cottage food laws in US states prohibit TCS foods entirely. In Guam, a properly licensed home kitchen operator can sell prepared TCS meals, provided their kitchen meets the inspection standard and they maintain proper food safety practices.
This is both an opportunity and a responsibility. Selling prepared meals from a licensed home kitchen means committing to the same temperature management, handling hygiene, and documentation practices expected of a restaurant or catering operation. The DEH inspects and enforces these standards. Violations can result in permit revocation and fines.
The most important practical requirement: you must have adequate refrigeration and, for hot-served products, hot-holding equipment. At markets and events, this means bringing a commercial-grade cooler with ice, a probe thermometer, and the ability to demonstrate safe temperatures to a DEH inspector if asked.
[VERIFY] Whether the Home Industry license specifically permits TCS prepared meal sales, or whether a separate food establishment permit is required for cooked meal production. Contact DPHSS/DEH at dphss-deh@dphss.guam.gov or (671) 646-1276 before selling prepared meals commercially.
Many of Guam's most iconic dishes are prepared meals that home cooks have made and shared for generations. Understanding how they classify under food safety rules helps you sell them confidently and legally.
Kelaguen (citrus-marinated chicken, shrimp, or beef) — TCS food. The lemon juice marinade does not fully cook the meat; the product must be kept refrigerated below 41°F and sold cold. Educate buyers on refrigeration and use within 24 hours.
Kadu (chicken or beef bone broth soup) — TCS food. Must be kept hot above 135°F for service, or rapidly cooled and refrigerated. Not suitable for room-temperature display.
Tinaktak (coconut milk ground beef dish) — TCS food. Refrigerated sale only; reheat instructions required on label. Red rice — TCS food (cooked grain). Must be kept hot or cold; never room temperature for extended periods.
Titiyas (flatbread) — generally shelf-stable if dry, without filling. Filled titiyas with meat or dairy fillings become TCS.
All liquid-based cooked dishes — including kadu, tinola, and CHamoru-style stews — are TCS foods. These must be sold either piping hot (above 135°F) with hot-holding equipment, or chilled to below 41°F for refrigerated sale or delivery.
CHamoru BBQ, adobo-style dishes, kelaguen (marinated chicken or beef), meat-filled pasteles, and other cooked meat preparations are all TCS. The underlying meat must come from an inspected source. Home-raised animals require USDA inspection before sale — see the Special Categories page.
Cooked rice — including CHamoru red rice (hineksa' aga'ga) — is a TCS food. Cooked rice held at room temperature is one of the most common causes of Bacillus cereus foodborne illness. Red rice sold for same-day consumption should be kept hot above 135°F; if sold as a packaged refrigerated side, it must be cooled rapidly and labeled clearly.
CHamoru empanada (filled pastry) with a meat or egg filling is a TCS product. The shell alone — if dry and unfilled — is shelf-stable. Once filled with meat, cheese, or egg-based filling, the whole product becomes TCS. Baked empanadas can be sold hot (above 135°F) at events or refrigerated for delivery and pickup.
All dishes with egg as a primary ingredient — quiche, frittata, egg-stuffed preparations — are TCS. Eggs must be cooked to an internal temperature of 145°F (intact) or 160°F (broken and scrambled). No raw or undercooked egg dishes for sale.
A plain cake or cookie is shelf-stable. The same cake filled with pastry cream, custard, whipped cream, or cream cheese frosting becomes a TCS product. Latiya (custard sponge cake) — one of Guam's most beloved desserts — is TCS and must be kept refrigerated below 41°F and sold with clear buyer guidance.
All refrigerated TCS foods must be held at or below 41°F. Use a calibrated probe thermometer to verify. Coolers with ice at markets should be checked every 2 hours.
Hot-held food at markets or events must stay at or above 135°F throughout service. Chafing dishes, insulated containers, and Sterno units are common solutions.
Minimum internal cook temps: poultry 165°F · ground meats 160°F · whole intact beef/pork 145°F · fish and seafood 145°F · eggs 145°F (intact) / 160°F (broken).
TCS food must not spend more than 4 cumulative hours in the danger zone (41°F–135°F). This includes prep, transport, and display time combined.
When cooling cooked food for refrigerated storage: reach 70°F within 2 hours, then 41°F within the next 4 hours. Use shallow pans, ice baths, or blast chilling.
DEH inspectors may ask to verify food temperatures. A calibrated digital probe thermometer is essential equipment for any home seller offering TCS products.
Under Guam's current framework, the Home Industry license allows food production from an inspected home kitchen — not a commercial kitchen. Your home kitchen must pass a DPHSS/DEH sanitary inspection meeting the Guam Food Code's retail food establishment standards, but it does not need to be a separately constructed commercial facility.
This is different from many US states where prepared meal sellers are required to use a licensed commercial kitchen. In Guam, if your home kitchen passes DEH inspection, it can serve as your production facility for both shelf-stable and TCS prepared foods.
However, if your production volume grows beyond what a home setup can safely support — or if DEH determines your kitchen cannot meet inspection standards — renting time in a licensed commercial kitchen is an option. [VERIFY whether shared commercial kitchen facilities are available in Guam and what licensing implications apply.] Contact DPHSS/DEH at dphss-deh@dphss.guam.gov for guidance specific to your setup.
