Is it safe to eat potatoes immediately after harvesting?

Prof. Martin Thorne, Ph.D.Whether potatoes can be eaten right after harvesting primarily depends on the type or condition of the potatoes. New potatoes with thin skins can be eaten right away, but they won't keep for long. Storage potatoes need to be cured before they are eaten. I learned that lesson after having stomach issues with uncured Russets.
New Potato Protocol
- Timing: Consume within 48 hours of harvest
- Preparation: Gentle scrubbing without peeling required
- Cooking: Boil or roast immediately after cleaning
- Storage: Never refrigerate - causes texture changes
Storage Potato Rules
- Mandatory curing: 14-day period before consumption
- Toxin reduction: Curing lowers glycoalkaloid levels
- Green handling: Cut away all green portions completely
- Bruised tubers: Must be cooked within 2 hours
Be extremely careful with green potatoes. Avoid eating green sections, regardless of how well-cooked, as heat does not break down the solanine toxin. Cut away the green parts, including at least a 1/2-inch margin, using a stainless steel knife. I use a separate cutting board for produce that is potentially toxic.
Proper curing converts storage potatoes into safe, long-keeping food. The 14-day process at 55-60°F helps thicken the skin and also reduces natural toxins. Once curing has taken place, store at 40-45°F for winter use, mine lasts till spring when properly stored!
