Japan's camping boom has made outdoor cooking an everyday pastime, and two kinds of accident have risen with it: food poisoning, and carbon monoxide poisoning inside tents. The points below follow the warnings issued by Japan's public bodies. Here is what to be extra careful about precisely because you are outdoors.
| Situation | Points | Basis |
|---|---|---|
| Carrying food | Cooler box with ice packs or ice. Meat and fish at the bottom, separated from other food. Keep it at 10°C or below | MHLW "Six points" |
| Hand-washing | If running water and soap are not available, wet wipes plus alcohol. Always after touching raw meat | Same |
| Cooking | Centre at 75°C for at least 1 minute. A charred surface on the barbecue and a raw centre are two different things. Campylobacter from chicken is the typical case | Same |
| Chopsticks and tongs | Separate ones for raw meat and for eating | Same |
| Leftovers | The rule is to throw them away, not take them home. Under a blazing sun, 2 hours is enough to make them dangerous | Same |
| Situation | Points |
|---|---|
| Stoves, charcoal, wood-burning stoves or cassette-gas heaters inside a tent or car | Prohibited (stated on the product label too). CO is colourless and odourless, so you do not notice |
| Ventilation | "It is fine if you ventilate" is wrong. Do not use outdoor combustion appliances inside a tent |
| Accidents | Deaths from carbon monoxide poisoning inside tents every year (reported by the Consumer Affairs Agency and NITE) |
| Disposing of charcoal | Put it out completely in a charcoal extinguishing pot (火消し壺, hikeshi-tsubo) or with water. Do not bury it in the ground (it smoulders for hours and causes burns) |
[Verify] Check the food-poisoning temperatures against the MHLW, the CO poisoning cases against Consumer Affairs Agency and NITE warnings, and charcoal disposal against individual campsites and the Ministry of the Environment.
Over charcoal, the surface chars first while the centre stays raw. Cut thick pieces to check, and cook chicken until the centre is white.
Opening and closing, and the outside air, push the temperature up. Use plenty of ice or ice packs, keep the box in the shade, and open it less often. Use the meat and fish first.
Gaps do not ventilate enough to stop CO, and because it is colourless and odourless you get drowsy without noticing. Combustion appliances stay outside the tent. More people now carry a CO alarm.
Food that has sat for hours under a blazing sun is dangerous even if it looks unchanged. The rule is do not take it home, even if it was cooked.
Buried charcoal smoulders for hours, and there are accidents where someone steps on it the next day and is burned. Seal it in a charcoal extinguishing pot, or douse it with water until it is completely out and take it to the designated disposal point.
