Cancer sucks. So does foodborne illness, like for the 53 people, primarily women, who died in Germany in 2011 from eating raw sprouts.

A holistic wellness coach who says she felt “dirty” after eating a non-organic veggie burger at a Byron Bay cafe has apologized after an online “rant” about the food she was served.

‘Wellness warrior’ Jessica Ainscough vented on her blog after eating a burger she believed was 100 per cent organic, only to later discover it was ‘not totally’ chemical-free.

The holistic health coach, who was in Byron Bay last week, follows a strict organic diet after overcoming cancer without using modern medicine.

In a June 18 post titled ‘BEWARE OF ORGANIC CAFES THAT LIE TO US’, Ms Ainscough said she was ‘pissed off’ that Manna Haven Cafe falsely claimed to be ‘vegan, raw and organic’.

The 26-year-old said she had initially been excited to find somewhere ‘safe’ for lunch and ordered the veggie Burger thinking it was organic.

The not-for-profit cafe’s menu describes its Big Burger as being ‘cancer fighting rather than cancer causing’ and vegan, low glycaemic index and a superfood.

“If a cafe claims to be organic and charge prices that reflect this, we should be able to trust that what they’re serving us is just that. Otherwise, it’s false advertising and on par with green washing.”

One of the cafe’s founders Anita Carvill saying she was shocked by the backlash.

“There was nowhere that said the burger was 100 per cent organic so I’m not sure how she got that impression,” Ms Carvill said.

“The options on the sign are just options, there is no false advertising.

Ms. Ainscough respoinded that, “The word ‘organic’ is the green light that tells us it’s safe to eat. It doesn’t matter if some of the ingredients are organic – if they’re mixed with conventional ingredients the whole dish is rendered poisonous to those of us who have to be so pedantic for the sake of our health and lives.”

Then avoid the sprouts. They tend to make people barf.
