Every generation seems to have its specific defining moment when a poignant event defines a culture and its people, such as the Apollo 11 moon landing or the tragic events of 9/11 or the shooting of John Lennon.
For Thomas Curley’s family, it was the Great Potato Famine that devastated Ireland between 1845 and 1852, marked by mass starvation, disease and caused a mass emigration to the New World.
It has been estimated that some 40 per cent of Ireland was solely reliant on the potato as a cheap crop, and after a potato blight ravaged the crops, over one million people died of hunger, with another million leaving the country—reducing total population by 20 to 25 per cent.
Originally from Monaghan County in Ireland, Curley emigrated to the Freetown/Summerfield area of Canada’s Prince Edward Island (PEI), establishing a farm growing mixed vegetables.
But perhaps because the quality of soil in the area is so suitable, the sixth-generation of Curley family farming at Monaghan Farms Ltd. today grows approximately 1,400 acres of potato-chip potatoes per year.
Along with the contract growers, the company grows on more than 3,000 acres of land in Canada’s smallest province.
ALL IN THE FAMILY
“While the acreage farmed has grown vastly over the years since Thomas Curley first arrived, I’m very proud that his original acreage is still being farmed by the Curley family today,” Monaghan Farm’s operation manager and co-owner Derrick Curley told Canadian Packaging magazine in a recent interview.
According to Statistics Canada, in 2014 Canadian farmers helped produce an estimated 4.6 million tones of potatoes, with PEI once again leading the way—harvesting over a quarter of all the country’s spuds.
“We’ve been farming this land for 160 years, with myself, my father and his father before him,” relates Curley. “For the past 14 years, after we first started exporting with West-Isle Enterprises to different Frito-Lay processing plants around the world, they have become our biggest customer.
“West-Isle Enterprises is our export business partner based out of Tyne Valley, PEI. Owned and operated by Rod Macneill, they handle the export logistics side of the business, while we manage more of the production side,” he explains.
Today, Frito-Lay Canada/International and its nearly 50 different brands of Lay’s brand potato chips are made with potatoes from Mongahan Farms, which ranks as one of PEI’s largest growers.
“My father Terry, who’s a co-owner like myself, took some of our potatoes as a sample to one of the Frito-Lay plants in Nova Scotia,” recalls Curley. “And I guess they must have been impressed, because they have helped us grow our business tremendously since then.”
Curley says that Monaghan Farms had previously supplied potatoes to other major food processors Old Barrel/Humpty Dumpty, Cavendish Farms and McCains, but now thanks to its exclusive contract with Frito-Lay, it has grown to become one of the largest exporters of chip potatoes in the world, with about 75 per cent of its potatoes destined for international markets.
“There are certainly quite a few established potato farms here in PEI, but Monaghan Farms may be the first such farm to create a large and ongoing export agreement,” he says.
“In fact, Monaghan Farms/West-Isle accounts for about 40 per cent of all the province’s raw potato exports shipped outside of the U.S,” he points out.
“While our own farm could be considered big, and our quality consistently high, it’s thanks to our geographic location and local weather that we often get that provides a perfect mix of sun and rain,” Curley confides.
“Also, the agreement we have with elite potato growers such as Shorelane Farms, Klondike Farms, Linkletter Farms and seed growers Marven Stewart, Heritage Farms and Blue Bay Farms, enables us to consistently meet the product demands of Frito-Lay so that they can produce their potato chips across Asia, the Americas and elsewhere.
“In order to maintain optimal soil health, we continually rotate our crops with forage crops like rye grass and clover,” he continues. “But we still aim to annually maintain approximately 1,400 acres to grow our chip processing potatoes.”
FROM THE GROUND UP
After being harvested from the ground by wind-rowers and harvesters, the potatoes are loaded onto trucks, unloaded at the Monaghan warehouse, cleaned, graded and piled into a storage bin area.
The harvested potatoes are held at a specific temperature, controlled by a computerized ventilation system to heal any wounds the spud may have accumulated during harvesting, as well as to dry out all moisture.
“Once that phase is complete, the potatoes are brought down to the proper storage temperature,” Curley relates.
“The storage bins are managed by myself and controlled by a computerized system that monitors temperature, carbon-dioxide and humidity levels, along with ventilation of the outside air.”
After storage, the potatoes are scooped up from the bins and unloaded inside the washing/grading plant, where the potatoes are washed, destoned, graded and run through a metal detection system before being loaded onto a trailer for direct shipment in bulk or in totes.
“We also have an IPM (integrated pest management) division, which performs crop scouting and quality monitoring in the field and in storage,” Curley points out.
“Quality is one of our main competitive advantages, so we are constantly measuring quality every step of the way, complete with our own quality control lab,” relates Curley. “Depending on the time of year, we measure all internal and external defects, solids and sugar analysis via fry tests and a special sugar analysis machine.”
Curley relates that Frito-Lay has specific requirements for potato sizes, dry matter (solids), internal potato sugar levels (it can reflect in the color of the chip after frying), and various internal and external defects.
The farm operates one main grading line—a washing/packing line with capability to load bulk and large totes.
Critical equipment on that production line consists of:
- three H.F. Stewart-built Even Flow hoppers and a Steel Drum washer;
- a destoner from Allan Potato Handling Equipment;
- a felt drier from H.F. Stewart;
- a Tomra Sorting Solutions automatic Odenberg Titan 2 sorter;
- three Fortress Technology Phantom metal detection systems with a slide and reject system;
- an automatic tote filler from Dunk River Industries;
- some in-house fabricated conveyors;
- a bin-piler from Allan Potato;
- a Kerian potato Speed Sizer machine.
“Our line is reasonably automated,” notes Curley, “and we can run the entire wash-plant grading facility with three people or less.”
Notably, the production line houses three Phantom metal detection systems, designed and manufactured by the Toronto-headquartered Fortress Technology.
As Curley explains, food growers don’t usually have such advanced food inspection equipment, opting to leave that responsibility to the actual processors themselves.
For Monaghan Farms, the decision to purchase the Phantom metal detection equipment was primarily borne out of urgent necessity.
“We had a regional food tampering issue that involved one or more people inserting metal objects such as needles into potatoes,” recalls Curley. “Naturally, our local customers insisted that we pre-screen our product for foreign metals to ensure better product safety.”
Back in October of 2014, darning needles began showing up in PEI potatoes sold in and around the Atlantic provinces, and while the tampered spuds were eventually traced back to a single farm in the Summerside area, no arrest was ever made.
At the time, nearly one million pounds of potatoes were recalled and checked for tampering, and all seemed well until March of 2015, when more needles were discovered in potatoes grown at other farms.
While many local PEI growers banded together to offer a $500,000 reward for the arrest of the culprit(s), the case still remains an open police investigation.
To better combat the problem of possible product tampering at its farms, many PEI farmers began purchasing metal detection equipment as a means to protect the province’s $1-billion potato industry.
“While we are quite keen to ensure consumers remain safe and the customer’s reputation remains unsullied, maintaining a positive reputation is also extremely important to all of us at Monaghan Farms,” Curley asserts.
“Some of our orders involve large volumes and are often shipped with a 30-day-plus transit time,” he continues, “and we didn’t wish to run into a situation where a large shipment could be rejected because of some foreign object in our product.”
Curley says that before the recent tampering, “To the best of my knowledge, no farm was metal detecting raw potato product in our area.”
Installed in the fall of 2015 in time for the harvest, Curley relates that he and his father wanted to take a bit of time to do proper research to see determine which detector worked best for their operation, noting that it was imperative that the farm’s production line not be slowed down.
Curley says that since installing the Phantom metal detection systems, Monaghan Farms has continued to run approximately 140,000 pounds of potato per hour, which is about the same speed before installing the food safety equipment.
“Fortress Technology provided us with its impressive Phantom metal detection unit that ensured sensitive detection, but did not limit our productivity by generating numerous false positive rejects,” explains Curley.
“Having technicians in the region was also important to us,” he adds. “If there ever is an issue with the metal detection unit, it is extremely comforting to know that they are reasonably close by.”
Fortress Technology says it has designed, manufactured and priced three different Phantom metal detection systems specific to potato processors and farmers:
- The Bulk Potato Slider Detector System is designed to handle loose, rolling potatoes, and features a Flap gate reject system and UHMW trough assembly.
- The Bagged Potato Detector System is designed for five- and 10-lb bagged potatoes and features a Belt stop alarm reject and complete conveyor assembly.
- The Bulk Potato Retract Detector System for bulk product inspection, featuring a Retract reject system and a complete conveyor assembly.
All systems also include BSH rugged casing—designed to provide better stability and performance in harsh environments where rolling potatoes are often banging into things.
In addition, Fortress Technology provides all its customers with local service and support; a test sample kit for calibration; quick delivery; a ‘never obsolete’ commitment (meaning Monaghan Farms will always be able to get parts and service for the life-time of their detector); performance certificate; startup and training; and two-year warranty on the detector head.
For its part, Monaghan Farms determined that the Bulk Potato Slider Phantom metal detection system would be its best choice, with Curley being advised by Fortress Technology that it would provide best sensitivity levels for the rolling potatoes.
As Fortress explained, metal in a rolling object provides a stronger signal than a stagnant metal object, with the chosen option providing Monaghan Farms with a lower sensitivity, while still providing metal detection accuracy with minimal false positives.
Utilizing a simplified conveyor system that could easily be integrated with their existing systems, it has a low-maintenance UHMW slider bed, and would provide the optimal cost-effective solution.
Purchasing three Phantom metal detection units elicited very positive feedback from Frito-Lay, according to Curley.
SAFE AND SOUND
“They were mostly concerned with ensuring the product is safe for its customers, and with the Phantom metal detection systems in place, that need has been effectively addressed.”
The farm production and packaging operation of Monaghan Farms is Canada GAP Certified, meaning it follows strict criteria to ensure its food products are 100-percent safe as they move through the product’s life-cycle.
“Our formal auditing body is SGS Canada, but we are also required to partake in random audits through worker safety compensation to ensure we also provide a safe working environment for our employees,” says Curley, crediting the efforts of his employees for making Monaghan Farms such a successful enterprise.
“None of this would be possible without them and we believe it is always important to be cognizant of that fact treating all our workers with due respect and gratitude.”
According to Curley, the farm also attaches a great deal of importance to environmental stewardship.
“The ALUS (Alternative Land Use Services) is a very effective program that was developed to retire higher-risk areas such as higher slope areas near waterways, as well as to ensure that we create an environmental farm plan that we strictly follow during crop production.
“Our industry can be very competitive,” reflects Curley, “especially when it comes to our international markets.
“We typically are not directly competing with local suppliers in the international markets, as processors generally have supply gaps when local growers can’t supply potatoes in certain times of the year due to timing differences in growing seasons.
“But we are competing against a number of exporters from various countries such as Australia, U.S., Egypt, and some European countries,” he concludes, “which is why consistent high quality is such a priority for us.
“It’s also why we appreciate the excellent food safety reliability we achieve with our Fortress Technology metal detection units,” he concludes.
“It helps to keep everyone safe and satisfied.”
