Yes, farmers wash potatoes, but often after initial storage, not right after harvest, because washing before storing can trap moisture and cause rot; they typically brush off loose dirt first, then use industrial washing systems (like water flumes) at packing facilities before shipping to supermarkets, while some processors want unwashed potatoes for specific uses like chips.
Once the potatoes are trucked into the shipping facility they are typically “flumed” in water along the conveyor belts to get rid of any dirt or sand and minimize bruising. Then the potatoes are allowed to dry.
If you need potatoes that will last a while, buy unwashed potatoes. Unwashed potatoes last longer than clean potatoes, as the dirt protects them from bruising. Only wash them just before you are going to use them.
It's generally recommended to wash potatoes before cooking or consuming them. Potatoes can harbor dirt, debris, or residues from pesticides or chemicals used during farming. Washing helps remove these impurities, reducing the risk of consuming harmful bacteria or substances that might be on the potato skin.
Washing with water and/or other solutions as well as the cooking process (blanching and frying) helped to eliminate most of the pesticide residues from the potato tubers.
The Dirty Dozen: Most Heavily Sprayed Foods
Answer. Conventional and organic potatoes are absolutely one of the best nutrition bargains available for a family to eat and I don't feel that scare tactics should chase you away from a food that is consumed year after year in huge quantities with very little risk.

Do You Need to Wash Potatoes? You sure do. “Since potatoes grow in dirt, it's important to wash them thoroughly before cooking, which helps prevent food-borne illness,” says RJ Harvey, RDN, CEC, culinary director at Potatoes USA, the national marketing and promotion board representing U.S. growers and importers.
Often grocery store potatoes (and usually ones from the farmers market) are pre-washed and will not sport large clumps of dirt like you'd see if they were pulled straight from the ground. However, if you grow your own potatoes or buy from certain farmers, then your dirt can very well be stubbornly stuck to your spuds.
The consensus among food-safety experts is yes, you should always wash your produce before eating or serving it.
The concentration of solanine is greatest in or directly beneath the skin, and peeling is an effective way to remove the solanine-affected tissue. Additionally, cooking in steam or water reduces solanine levels by 30 to 40 percent. Growers and retailers should reduce factors that contribute to greening.
It all starts with fresh, firm potatoes. They're washed, peeled, and cut into chunks, ensuring even cooking. Then, they're packed into sterilized glass jars and covered with boiling water or a light salt brine. No preservatives, just nature's way of keeping food fresh.
Seed potato tubers can store glyphosate residues until the following year, and when planted they can have emergence problems that ultimately can reduce yield. Glyphosate is a commonly used herbicide in agriculture because of the low cost for effective control of grasses and broadleaf weeds.
The skins of potatoes can have stubborn dirt on them, and if you don't have a dedicated vegetable scrubber on hand, fret not. You can easily slough the grime away using nothing but a clean dish towel.
Peeling potatoes was similarly effective among both pesticide classes removing 70.7-75.3% of residue. Cooking potatoes via blanching and frying removed 22.9-47.3% and 30.12-53.4% of pesticides respectively. A tap water rinse was ineffective in removing pesticide residues, only removing 11.2-23.7% of residue.
Answer. All potatoes are flumed in water as they go down the sorting lines and washed before being packed into cartons or bags, it doesn't hurt to rinse them one more time to get any surface dirt or sand off the potatoes you receive. Boiling in hot water is just going to push around any dirt particles or sand.
Healthiest: Bake
Baked potatoes are considered to be one of the healthiest ways to enjoy your spuds, especially if you eat the skin. The process of baking allows them to keep hold of their nutrients more than with boiling, and the lack of oil keeps the calorie count down.
A ricer or food mill is the secret tool restaurants use to get that smooth and creamy texture without any gluey starch. It makes the biggest difference and it is actually so fun to use. Your holiday potatoes will never be the same after this!
All fruits and vegetables should be washed thoroughly before eating. Rinsing and scrubbing everything from celery and peppers to the ever-versatile potato is necessary to remove both dirt and chemicals such as pesticides. Because potatoes grow underground, they come up looking a bit dirty.
What is the healthiest potato?
The Dirty Dozen is a list of 12 fruits and vegetables that have the highest levels of pesticide residues. It includes strawberries, spinach, kale, nectarines, apples, grapes, peaches, cherries, pears, tomatoes, celery, and potatoes.
Testing found the highest levels of pesticides in spinach — with more pesticide residue by weight than any other produce tested — followed by strawberries, kale (along with mustard greens and collards), grapes, peaches, cherries, nectarines, pears, apples, blackberries, blueberries and potatoes.
