Many are surprised, he said, to learn they cannot simply make their food and sell it without meeting regulations designed to ensure food safety. And those rules apply equally to large food manufacturers as well as mom-and-pop operations, he said.

Arritt also serves as North Carolina’s “process authority,” the only person in the state able to provide U.S. Food and Drug Administration-required letters confirming that a company’s intended processes for making certain acidified foods are safe.

Acidified foods are those that depend on acidification as part of the process to ensure safe products. Naturally acid foods and fermented foods, along with jams, jellies, preserves and dressings that meet regulated standards, are exempt. However, if the food contains a mixture of acid and low-acid foods, the regulations may apply.

For makers of the latter foods, Arritt offers training designed to help them pass a required certification exam. In 2010, he conducted Extension’s three-day Acidified Foods Processing and Packaging Better Process School, commonly known as “the pickle school,” five times in different areas of the state. Currently the North Carolina State training is the least expensive anywhere in the United States, Arritt said.

The training covers such topics as microbiology of thermally processed foods, food plant sanitation, container handling, record-keeping and container closures.

While the regulatory requirements can be daunting, the consequences of not following recommended processes for acidified foods can be dire, Arritt added. Without adequate acidification, microorganisms — such as the one that causes botulism — can grow in the foods and make consumers sick.

“If you do things wrong, you can kill people. So it’s a very serious thing,” Arritt said. “I tell people who come to us, ‘Helping you make money is important; it’s my second priority. But food safety is my No.1 priority.’”

Fulton, of Miss Jenny’s Pickles, told MSNBC-TV on a November episode of “Your Business” that she and Furr wanted to start their business right — and that meant starting with North Carolina State University’s help.

She and Furr worked with Arritt to have North Carolina State test their products and create their nutritional labels, took part in the intensive pickle school and had their pickle-making process approved by the FDA. They’ve also consulted with Arritt on such issues as pickle crispness.

Since Fulton and Furr started the business in August 2009 in Kernersville, they have rapidly expanded, now selling in 55 stores and through the national fine food retailer Dean & Deluca, Fulton said.

The success comes, she said, with the “old-fashioned experience” that the family recipes provide. But North Carolina State has had an important role in helping the company get established, she added.

“It’s like they say — you don’t know what you don’t know,” she said. “And the knowledge we walked away with from Fletch and North Carolina State — we use what we learned every day. Without them, none of this is possible.”
