coli-contaminated produce are most often due to produce coming into contact with contaminated irrigation water, indoor growing provides an ideal solution with zero reliance on irrigation water.

How does E. coli enter food?
Shiga toxin-producing E. coli (STEC) is a bacterium that can cause severe foodborne disease. Primary sources of STEC outbreaks are raw or undercooked ground meat products, raw milk, and faecal contamination of vegetables.
How do bacteria get into vegetables?
Microbes can be transferred from one food to another by using the same knife, cutting board or other utensil without washing the surface or utensil in between uses. A food that is fully cooked can become re-contaminated if it touches other raw foods or drippings from raw foods that contain pathogens.
Does washing vegetables get rid of E. coli?
In a word, no. According to James Rogers, Ph. D., director of Food Safety and Research at Consumer Reports, if E. coli (or any other type of bacteria that can cause food poisoning) is present in your produce, washing it won’t remove all of those organisms.
Can you get E. coli from unwashed fruit?
