# Indoor Farming and Food Safety: What the FAO’s First Global Review Reveals

 September 19, 2025

3 Min Read

## Indoor farming, ranging from vertical farms to hydroponic systems, is expanding worldwide as a solution to food security and urban supply challenges. 

## But a new [**global review**](https://openknowledge.fao.org/handle/20.500.14283/cd6554en) from the **Food and Agriculture Organization (FAO)** highlights that food safety practices in these systems remain inconsistent, with risks varying depending on water use, lighting, growing media and post-harvest handling.

Few countries have tailored regulations for these systems, meaning producers often rely on general food safety rules. The report stresses the need for clearer guidelines to address the unique risks of soilless growing environments.

## What Is Indoor Farming?

Indoor farming refers to growing crops in controlled environments such as** greenhouses**, **hydroponic systems** and **vertical farms**. These systems can reduce pesticide use and make fresh produce available closer to cities. 

However, because they differ from traditional farms, they also introduce unique food safety challenges that must be carefully managed.

## What Are the Main Food Safety Risks in Indoor Farming Systems?

### Water Quality and Contamination

Since water is often the primary growing medium in hydroponics and aquaponics, contamination with pathogens or chemicals poses a major risk. The FAO notes that improper monitoring can lead to **widespread contamination** if one source is compromised.

### Lighting, Humidity and Pathogen Growth

Controlled environments use artificial lighting and regulated humidity. While these help optimize growth, they may also create **conditions that favor mold, fungi or bacteria** if not properly balanced.

### Plant Growing Materials

Materials used to grow plants, such as **coconut fibre** or **rockwool**, can carry germs if they aren’t cleaned properly. The nutrient-rich water used in these systems also needs close monitoring to stop bacteria from growing.

### Post-Harvest Handling and Storage

As with traditional farming, **contamination risks** remain during harvesting, packaging and transport. Without strong hygiene practices, produce grown in sterile environments can still become unsafe.

## How Is Indoor Farming Regulated Worldwide?

Most countries apply general food safety standards to indoor farms rather than industry-specific rules. The FAO highlights that this regulatory gap may leave certain risks under-addressed. In the U.S., the [**Food Safety Modernization Act (FSMA)**](https://www.fda.gov/food/guidance-regulation-food-and-dietary-supplements/food-safety-modernization-act-fsma) covers produce safety but does not specifically address indoor farming practices.

## What Does the FAO Recommend for Safer Indoor Farming?

The report calls for:

1. Stronger monitoring of water quality and nutrient solutions
2. Development of international guidelines specific to indoor farming systems
3. Investment in research to understand emerging risks
4. Training programs for workers to manage hygiene in high-tech environments

## What This Means for U.S. Food Businesses and Consumers

For U.S. food operators, the FAO’s findings reinforce the need for robust training and compliance with FDA requirements. 

**Food Handlers** and **Food Protection Managers** should be trained to recognize the unique risks of indoor-grown produce, from waterborne pathogens to handling practices. Consumers can feel confident that these systems can produce safe food, but only when supported by strong oversight and transparent standards.

## Frequently Asked Questions

### Is indoor farming safer than traditional farming? 

It can reduce pesticide use and contamination from soil, but risks still exist, especially with water and humidity control.

### Who regulates indoor farming in the U.S.?

The** Food & Drug Administration (FDA) **oversees produce safety under FSMA, but there are no specific rules for indoor farming yet.

### What are the biggest food safety risks in indoor farming?

**Water contamination**, **unsterilized growing materials** and **poor post-harvest hygiene** are all significant risks to food safety associated with indoor farming.
