Most food poisoning from cooked food is not caused by the cooking. It happens afterwards, when rice, chicken, curry goat or soup sits warm for too long, cools too slowly overnight, or gets reheated only part of the way. For a cook shop, school canteen, church kitchen or caterer in Jamaica's heat, the temperature of food between the pot and the plate is where the risk is.
This guide sets out the temperature rules used in the U.S. Food and Drug Administration (FDA) Food Code and by the U.S. Department of Agriculture's Food Safety and Inspection Service (FSIS). Jamaica has its own public health regulations, so always follow what your parish health department asks for, but these figures are a widely used, science-based reference point for any food business.
The danger zone in one line
FSIS describes the "danger zone" as 40°F to 140°F (about 4°C to 60°C), the range where bacteria grow fastest. The Food Code uses slightly different working limits for businesses: keep cold food at 41°F (5°C) or below and hot food at 135°F (57°C) or above. Everything in between should be passed through quickly.
The five temperatures every kitchen should know
| Stage | Target | Why it matters |
|---|---|---|
| Cooking poultry (chicken, turkey) | 165°F / 74°C internal | FSIS safe minimum internal temperature |
| Cooking ground beef or pork | 160°F / 71°C internal | FSIS safe minimum internal temperature |
| Cooking fish | 145°F / 63°C internal | FSIS safe minimum internal temperature |
| Hot holding (bain-marie, steam table, warmer) | 135°F / 57°C or above | Food Code hot-holding limit |
| Cold holding (fridge, cooler, salad bar) | 41°F / 5°C or below | Food Code cold-holding limit |
| Reheating cooked food for hot holding | 165°F / 74°C, reached within 2 hours | Food Code reheating rule |
A probe thermometer is the only way to know. Colour, steam and "it's bubbling" are not reliable, especially in the middle of a deep pot of stew or a full tray of rice.
Hot holding: keeping lunch safe until it is sold
- Start hot. Food should go into the warmer already above 135°F (57°C). Hot-holding equipment is designed to keep food hot, not to heat cold food up.
- Stir and check. Probe the centre of each pan at regular times, for example every two hours, and write the reading down.
- Cover pans where you can, and keep pans shallow enough that heat reaches the middle.
- Do not top up old food with new. Mixing a fresh batch into a pan that has been out for hours mixes the risk into the fresh food.
- Know your cut-off. If a pan has dropped below 135°F and you do not know for how long, the safe choice is to throw it away rather than serve it.
Cooling: the step most kitchens get wrong
Large pots of rice and peas, soup, curry or stew cool very slowly because the centre stays warm for hours. The Food Code sets a two-stage limit for cooling cooked food:
- From 135°F to 70°F (57°C to 21°C) within 2 hours, then
- From 70°F to 41°F (21°C to 5°C) within a further 4 hours, so no more than 6 hours in total.
Practical ways to hit those times:
- Divide big batches into shallow pans instead of leaving one deep pot to cool.
- Use an ice-water bath: stand the pan in a sink or basin of ice and water and stir.
- Cut large joints of meat into smaller pieces before chilling.
- Leave lids slightly open at first so steam can escape, and do not stack hot pans together in the fridge.
- Do not leave food on the counter overnight "to cool down". FSIS advises that perishable food should not sit out for more than 2 hours, or 1 hour when the air is above 90°F (32°C), which is common in a Jamaican kitchen.
Reheating leftovers
If cooked food has been cooled correctly and will be hot-held again, the Food Code says to reheat it so that all parts reach 165°F (74°C), and to do it quickly, within 2 hours. Reheat on the stove or in an oven, not in the hot-holding unit. Reheat only what you expect to sell, because food that has been cooled and reheated more than once loses quality and gives bacteria more chances.
Cold holding and deliveries
- Put a thermometer inside every fridge and chest freezer and check it at opening and closing.
- Do not overload fridges. Cold air has to circulate around the food.
- When meat, chicken or fish arrives, put it away first, before dry goods.
- During a power cut, keep doors closed. Our guide to food safety when the power goes out explains what to keep and what to throw away.
A simple temperature log you can copy
A written log shows staff what to check, and shows a health officer that you check. One sheet a day is enough for most small kitchens:
| Time | Item / pan | Reading | Action taken | Initials |
|---|---|---|---|---|
| 11:00 | Fried chicken, warmer | |||
| 11:00 | Rice and peas, warmer | |||
| 13:00 | Fridge 1 | |||
| 16:00 | Curry goat, cooling (start) | |||
| 18:00 | Curry goat, cooling (2 hours) |
Check your thermometer is accurate now and then. A common method is to stand the probe in a glass packed with ice and a little water: it should read 32°F (0°C).
Staff habits that back up the numbers
- Wash hands before handling cooked food and after handling raw meat.
- Keep separate boards and utensils for raw and cooked food.
- Label cooled food with the date it was cooked.
- Make sure every food handler has the permits and training your local health department requires.
