That depends on how long someone smoked in the room. You can do things like wash linens that were on the bed when a person smoked in the place, use Febreze on the couch if it is cloth, and on window drapes, and open all doors and windows when it is warm enough, to let the fresh air in.
Milk can stay at room temperature for about 2 hours before it starts to spoil. After that, it should be refrigerated to keep it fresh.
Cooked salmon should not be left at room temperature for more than 2 hours. If it has been left out longer than that, it should be thrown out because bacteria can grow quickly at room temperature. If the salmon is smoked, it should not be left out at room temperature for more than 3 hours.
Depending on the fruit and the temperature of the room, some fruits should be good for a week or more, possibly two. Bananas may not last as long as other fruits.
In general, smoked meat steaks, or any food for that matter, should not stay out of the fridge for more than 4 hours. This is because foods that sit at room temperature are in the Temperature Danger Zone (TDZ for short), which ranges from 41oF to 135oF. Since the average room temperature is between 60oF and 72oF, room temperature foods have a much higher chance of collecting germs that will grow in the food (like a smoked meat steak) than if it is left in the fridge, which has an average temperature of 25oF to 34oF, which is outside the TDZ.
Milk can sit out at room temperature for about two hours before it starts to spoil. It is best to refrigerate milk promptly to keep it fresh.
A fresh pineapple typically lasts for about 3-5 days when stored at room temperature before it starts to spoil.
Cooked pasta should not be left out at room temperature for more than 2 to 3 hours. Any food that is left out at room temperature after cooking can be dangerous at any time past the 4 hour mark.
UHT (ultra-high temperature) milk, also known as long-life milk, stays fresh the longest at room temperature compared to other types of milk. It has been processed at a higher temperature to kill more bacteria, allowing it to be stored without refrigeration until opened.
