Idaho Potato Harvest Tour Part 2: All About Potatoes


potato storage

Have you ever seen so many potatoes?   Imagine 13 billion pounds of potatoes…that’s how many are harvested each year in Idaho on 300,000 acres.  94 per cent of those potatoes are russets like these…and there are different varieties of russets too:  Burbank,  Norkotah, Ranger, and Western, to name a few.  Idaho potato farmers also grow gold, pink, red, and fingerling potatoes.   Only about 29% of those  potatoes are for eating fresh, and  9%  are for seeds. More than 60 per cent of all the potatoes grown are processed:   frozen (french fries, hash browns, tater tots. etc.)  or dehydrated as potato flakes and slices for  instant mashed potatoes and casseroles.

Last week I was lucky enough to visit Idaho to celebrate the harvest with Idaho Potato Commission.  I joined a small group of food bloggers and  registered dietitians on tours of  farms and potato processing facilities.  On our first full day in Idaho we all piled into a bus  and drove through the beautiful Idaho countryside.  Acres and acres of potato fields had been readied for the harvest…plants cut and removed…potatoes in the ground, waiting for the harvest.  Rainy weather was delaying the farmers,  who needed the soil to be dry and dusty in order to get the machinery into the fields.


Our first stop was in American Falls at the Lamb Weston processing plant,  the first one built in the 60’s by Lamb Weston to make frozen potato products, specifically french fries!  We removed all our jewelry,  donned hair nets and hard hats,  signed into the visitors log book,  and were ushered through the labyrinth of hallways to a conference room.   There we saw a movie about Lamb Weston with an introduction to what we would see in the plant. It’s a good thing we saw that movie too, because it was so noisy inside the plant we could hardly hear our guides’ narrations.  We learned how the potatoes are cleaned and how the skins are removed.  We saw the special knives that cut the potatoes into fries,  and innovation developed by Lamb Weston years ago that has come an industry standard.

Washed and ready for the next step.

We split up into small groups,  climbing metal stairs, walking the cat walks, and observing all the intricate machinery that produces the  cut and fried potato products we all love to eat.   Later we were treated to samples of the foods they make, including McDonald’s french fries, sweet potato puffs, and jalapeño poppers.   Each of the products they make are done to exacting standards dictated by their customers.   Quality control and food safety are huge priorities in the plant.  I was impressed that the people we met who work there have been doing their jobs for decades,  taking enormous pride in their jobs and the company as a whole.  Later I looked up Lamb Weston,  and learned that they deserve to be proud of a legacy that includes some of the greatest innovations made over the last 60 years in the frozen produce industry.

Wada Farms

Our next stop was Wada Farms,  a 4th generation  family operation that began in 1943 when Frank and Agnes Wada moved to Idaho to avoid internment during World War II,  having moved from Japan to farm  in San Clemente, Ca. in 1922.  They started with 160 rented acres, increasing to 400 acres by 1972 when Frank retired,  to over 30,000 acres in production today.  The company motto is “Pride in Excellence”, and it is evident that the family’s adherence to that philosophy has contributed to their success.

Wada Farms visitHere we were welcomed in the conference room by Chris Wada,  the grandson of Frank and Agnes,  who has joined his brother in the family business.  He told us how his grandfather had corresponded with Albert Einstein as a pen-pal, and how his father Albert was named for the renowned physicist.  One of the dietitians in our group works with the Pittsburg Steelers, so we had some light moments with a Wada manager who is a big Steelers fan.  Again we removed our jewelry,  put on nets, ear-plugs, hard hats,  and walked through the plant to see potatoes cleaned, sorted, packaged, and wrapped for specific consumer uses.   This family has mastered the art of “vertical integration”:  growing,  storing, processing, packaging, and marketing their potatoes themselves.

All those potatoes moving through the machinery reminded me of a huge Mousetrap Game…or a choreographed dance!

easy grillersOne innovative marketing technique Wada Farms has done  is to wrap potatoes in foil for grilling or plastic for microwaving.  If you see “Easy Grillers” or  “Easy Bakers” in your store,  you’ll know they came from Wada Farms.

potato conveyerThe potatoes are unloaded from the trucks to this long conveyer, which carries the them one by one  into the long concrete building.   As the potatoes are loaded in,  large metal culverts that have holes drilled along their length are laid cross-wise on the floor underneath the potatoes.  Cool mist and air is blown with fans  into the metal tubes to keep the potatoes at a consistent humidity and temperature so they will remain fresh during the months they may be stored.  Each storage can hold up to 80,000 sacks of potatoes.

long view of storageHere you can see the metal pipes lined up on the sides of the building, with pipes laid in front of the growing pile of fresh potatoes.  I must admit that seeing the huge pile of potatoes was exciting and impressive!

Are you enjoying the trip so far?   It’s fun to remember all that we saw and especially the warm welcome we received each place that we visited.   We were disappointed that the weather wasn’t cooperating for the farmers’ harvest,  and didn’t expect to be able to see any potatoes being harvested at all.   Our hosts from the Idaho Potato Commission made some phone calls and found a farmer who was willing to let us visit his fields later in the afternoon.   As we drove back toward Idaho Falls, we took in the huge open farm fields and the beautiful cloud formations in that enormous sky.  It had been a long day, but we were giddy with anticipation!   We were going to dig up potatoes ourselves on an Idaho potato farm!
