Food sanitizer (Fallout 3)

The Food Sanitizer is a special item that, according to in-game dialogue, will cleanse most food in the inventory of harmful bacteria, allowing greater nutritional gain. It is awarded after completing the optional Super Duper Mart objective of the The Wasteland Survival Guide quest.

Use and Effects
Food Sanitizer has a passive effect on the player as long as it is in the player's inventory (WG7). While in the player's inventory, Food Sanitizer will increase HP value of food by 20%. Food Sanitizer has no effect on radiation rating of the food. (Player will receive the same Rad from food with or without Food Sanitizer).

To reduce the radiation you get from foods, you need to boost your Radiation Resistance.

The base radiation for all foods is 3. At 67% radiation resistance, you will not get any Rad from basic foods.

Since endurance provides some level of radiation resistance, and the radiation you get is rounded down, you will never get 3 rads from eating basic food. It will most likely be 2 for large majority of people, and 1 if you hit 34%.

Since it disappears from your inventory, the food sanitizer is temporarily disabled when you enter the simulation in Vault 112, when you are captured by Colonel Autumn and when you enter the Operation: Anchorage Simulator located in the in the Outcast Outpost.
