CARLA McLean laughs easily with the stall owner as she loads fruit and vegetables into her shopping basket.

The owner knows her well –she is one of the many regulars that choose to buy organic produce.

Carla, 33, visits the Sunday markets each week to restock her fruit and vegetable reserves.

She believes that organic food is better –better taste, better for health and better for the environment –and she shops accordingly.

“I don't want to eat chemicals,” she said. “And it tastes better.”

Her arm is shaking with the weight as she crashes the now overflowing basket of fresh produce onto the counter and hands over her recycled bags.

Carla has been on the organic journey for about eight years but it was when she fell pregnant she started to take it even more seriously.

“We eat about 90 per cent organic and have a chemical-free house,” she said.

“The way I see it, we are investing in preventative medicine –investing in our bodies,” she said.

Mr Organic's stall is a regular sight at the PCYC Markets on James Street each Sunday.

Murray Griffith (Mr Organic himself) has been there for more than four years and has noticed a remarkable increase in customers over that time.

He said people want to have more control over what they eat and are thinking a lot more about where and how products are sourced.

The increase he has noticed mirrors a study by the Biological Farmers of Australia, a non-profit industry group, showing that sales of organic produce have increased by 80 per cent since 2004 and are worth about $220 million a year.

The Mr Organic stall has a constant stream of customers. Some buying their weekly shop others just picking a few. He also boxes up produce and couriers out organic produce out west.

Murray is a firm believer in the power of organic food.

“What goes into your body needs to be as pure as possible,” he said.

“The chemicals and additives, I believe can cause disease later in life.”

The Pateman's family Homegrown Health stall at the markets is also very busy with market goers stocking up on the fresh, local produce.

Darrin and his wife Kyle decided to become self sufficient and organic on their nine-acre Cabarlah property with the health of their three daughters –Sam, Katie and Allie – in mind.

One week Mr Pateman had an excess of produce so they came to the markets, their business has grown from there.

Every week Mr Pateman seems to be putting more and more garden beds in and also sources produce from other local farmers.

“People want good, fresh, organic produce that is locally grown,” he said.

“People are really waking up to the benefits of organics.”

The strong demand for organic produce also comes with strict guidelines.

To be certified organic, farmers must conform to stringent regulations that cover every step of the production process.

The Pateman's farm is rated pre-certified and is currently undergoing certification with the Australian Certification Office.

The process takes four years and involves audits, samples, record keeping and soil testing.

Organic farming is usually more labour intensive and on a smaller scale than conventional agricultural methods, which explains the higher prices paid by consumers.

But a glance around the stall brimming with quality chemical-free produce, the fruit and vegie prices are on par with the supermarkets.

Homegrown Health is the very essence of a true family business with Darrin, Kylie and the girls picking the crops on Friday and Saturday to be sold at the markets on Sunday.

Renee Fletcher, 30, is also a market regular.

“I like to support and buy produce from local farmers,” she said.

For Renee the organic choice is easy.

“It is important not to use chemicals because of the impact on the environment. It is also a lot healthier as you don't know what chemical residue is left on the products,” she said.

She said it was difficult to be completely organic but it was a decision by her to buy organic where she could and budgeted accordingly.

“We decided we would spend a bit more money on food and being organic and cut back in other areas.”
