Iconic actress Michelle Pfeiffer has launched a shocking attack on billionaire Bill Gates and suggested he's going to contaminate America's food supply.  

In an extraordinarily rare move for the low-key actress, Pfeiffer took to Instagram on Thursday to express concern over the FDA's approval of Apeel, a Gates-backed food coating meant to extend the shelf life of produce.

'Apeel (an edible, plant-based coating designed to extend the shelf life of fresh fruits and vegetables) was just approved and now "organic" produce is coated in something we cannot see or wash off,' Pfeiffer wrote.

'Very concerning.'

The Scarface star, 67, wrote the message as she shared a video that claimed 'organic produce is no longer safe' after 'Bill Gates' Apeel just approved for USDA-certified organic.' 

Apeel has long been mired in controversy over its ingredients and association with Gates. 

The company was founded in 2012 by entrepreneur James Rogers with the help of a $100,000 grant from the Bill & Melinda Gates Foundation. 

The Gates' are not currently involved in Apeel, which has received substantial backing from venture capitalist Andreessen Horowitz. 

Pfeiffer's comments might come as a shock to her fans, as the Batman Returns icon is famed for living a quiet life and avoiding the type of controversial declarations often made by many of her Hollywood peers.

Despite Pfeiffer's comments, Apeel claims on its website that their coatings can be washed by rinsing the produce with water and scrubbing it.

Apeel uses plant lipids or plant oils naturally found in fruits and vegetables and creates a coating applied 'to the surface of fresh fruits and vegetables in order to retain moisture and reduce oxidation,' Jenny Du, co-founder of Apeel and senior vice president of operations told the Associated press

'Our product is also intended to be edible."'

The coating consists of purified monoglycerides and diglycerides, which Du pointed out are also found in products such as infant formula. 

The company has said their coating technology can help reduce post-harvest food waste in developing countries and is ultimately aimed at combatting famine and hunger.
