# AI tells a user that raw almonds are safe to eat if blanched (boiled briefly and skins removed)

- **ID:** `food-safety/ai-says-raw-almonds-are-safe-after-blanching`
- **Domain:** food-safety
- **Category:** health_risk
- **Error Code:** `RAW_ALMOND_BLANCHING_SAFETY_MISCONCEPTION`
- **Verification:** ai_generated
- **Fix Rate:** 70%

## Root Cause

Raw almonds in the US are required by USDA to be pasteurized (steam, oil roasting, or propylene oxide treatment) to reduce Salmonella risk; blanching at home (boiling for 1-2 minutes) may not reach sufficient temperature or time to kill Salmonella, and removes only the skin.

## Workarounds

1. **Spread raw almonds in a single layer on a baking sheet. Roast at 350°F (177°C) for 10-12 minutes, stirring halfway through. This achieves a 5-log reduction of Salmonella. Let cool completely before storing. Use a food thermometer to ensure center reaches 165°F.** (95% success)

2. **Look for almonds labeled 'roasted', 'dry roasted', or 'steam pasteurized' on the package. These have undergone USDA-approved treatment. Avoid 'raw' almonds unless you plan to roast them yourself.** (90% success)

## Dead Ends

- **** — Salmonella can survive 3 minutes at 212°F if the almonds are cold; the center may not reach lethal temperature; USDA pasteurization requires 4-log reduction, which boiling may not achieve. (80% fail)
- **** — Salt water does not kill Salmonella; it may actually promote bacterial growth if left at room temperature. (90% fail)
- **** — All almonds sold in the US must be pasteurized by law; 'raw' almonds from farmer's markets are still pasteurized (usually steam); the risk is from the pasteurization process itself, not the source. (60% fail)
