Cheese is a beloved staple in many households across the United States, but few consumers realize that approximately 90% of U.S. cheese contains a genetically modified (GMO) ingredient—one that is not required to be disclosed on non-organic cheese labels. This ingredient, known as chymosin, is a microbial rennet used in cheese production to separate curds from whey. What makes this revelation even more concerning is who manufactures it—the pharmaceutical giant Pfizer.

This analysis explores what chymosin is, why it is a controversial ingredient, the implications of its use in non-organic cheese, and what consumers can do to make more informed choices about their dairy products.

The History of Cheese-Making and the Shift to GMO Enzymes

Cheese-making has been around for thousands of years, with traditional methods relying on animal-derived rennet. Rennet, an enzyme extracted from the stomach lining of young calves, was historically the only way to separate milk into curds and whey.

However, as cheese production scaled up to meet the growing demands of industrial food systems, sourcing natural rennet became costly and impractical. This led to the development of microbial and genetically engineered rennet substitutes like chymosin. Today, GMO-derived chymosin dominates commercial cheese-making, even though most consumers are unaware of its presence.

How GMO Chymosin is Created

Chymosin is produced by inserting a genetically modified gene into bacteria, fungi, or yeast. These microbes are then fermented to create an enzyme that mimics natural rennet, allowing large-scale cheese production without relying on animal-derived enzymes.

While this process makes cheese-making more efficient and cost-effective, it raises ethical, environmental, and health concerns—especially given the lack of disclosure about its GMO origins.

The Controversy Around GMO Chymosin

1. The Lack of Labeling Transparency

One of the biggest issues surrounding GMO chymosin is that non-organic cheese manufacturers are not required to disclose its presence. In the U.S., genetically modified enzymes are considered processing aids, which means they do not need to be labeled as ingredients.

This means that millions of Americans are consuming genetically modified enzymes in cheese without their knowledge—something that would be unacceptable to many if they were made aware.

2. Who Manufactures Chymosin?

Perhaps one of the most shocking revelations is that Pfizer is one of the key producers of GMO chymosin. While many associate Pfizer with pharmaceuticals, few realize that the company has a history in biotech food production, particularly in genetically engineered enzymes used in food processing.

For those who are wary of the pharmaceutical industry’s involvement in the food supply, the idea that Pfizer is behind a key component of their cheese raises ethical and trust concerns. Consumers who actively avoid GMOs may feel misled, as they may unknowingly be ingesting genetically engineered ingredients.

3. Potential Health Concerns

While regulatory agencies like the FDA and EFSA (European Food Safety Authority) have deemed genetically engineered chymosin safe, many health-conscious consumers remain skeptical.

Potential concerns include:

• Long-term effects of GMO consumption: While GMOs have been widely studied, some researchers argue that long-term human studies on GM enzyme consumption are lacking.
• Alteration of gut microbiome: Some studies suggest that certain genetically modified foods and additives can alter gut flora, leading to digestive and immune issues.
• Ethical concerns: Many people prefer to avoid genetically modified ingredients due to philosophical or religious beliefs, and the lack of labeling prevents them from making informed choices.

Why the U.S. Allows GMO Chymosin in Cheese

Unlike many other countries, the United States has more lenient regulations on GMOs and food labeling. While the European Union enforces strict GMO-labeling laws, the U.S. has repeatedly loosened restrictions on bioengineered food products.

Some key reasons for the widespread use of GMO chymosin in American cheese include:

• Cost-effectiveness: Chymosin production is significantly cheaper than harvesting traditional calf rennet, making it attractive to large-scale cheese manufacturers.
• Efficiency: Genetically engineered enzymes provide more consistent results in industrial cheese production.
• Regulatory loopholes: Since chymosin is classified as a processing aid rather than a food ingredient, it escapes the scrutiny required for full ingredient disclosure.

This regulatory environment means that unless consumers actively choose organic or non-GMO verified cheese, they are likely consuming genetically modified enzymes without realizing it.

How to Avoid GMO Cheese and Make Informed Choices

If you’re concerned about consuming GMO-derived cheese, there are several steps you can take to make more informed choices:

1. Choose Organic Cheese

Under USDA Organic regulations, certified organic cheese cannot contain genetically modified ingredients. Organic cheese manufacturers must use natural rennet or microbial enzymes that are non-GMO.

2. Look for Non-GMO Verified Labels

The Non-GMO Project Verified seal is a good indicator that a cheese product does not contain genetically modified enzymes. However, not all non-GMO products carry this label, so additional research may be necessary.

3. Support Small-Scale and Artisanal Cheesemakers

Many small, independent cheese producers still use traditional rennet or non-GMO microbial enzymes. Supporting these businesses not only ensures a higher quality product but also promotes transparency in food sourcing.

4. Contact Brands Directly

If you’re unsure whether a cheese brand uses GMO chymosin, reach out to them directly. Many companies are willing to disclose their production methods, and consumer inquiries can encourage brands to adopt more transparent labeling practices.

5. Consider Plant-Based Cheese Alternatives

For those who want to avoid GMOs altogether, plant-based cheeses made from nuts, seeds, and fermented ingredients provide an alternative that does not rely on genetically modified enzymes.

The Environmental and Ethical Considerations of GMO Chymosin

While GMO chymosin has made cheese production more efficient, it raises ethical and environmental concerns:

• The Role of Big Biotech in Food Production: Many consumers feel uncomfortable knowing that pharmaceutical and biotech corporations influence food production without transparent labeling.
• Impact on Traditional Cheese-Making: Mass production of GMO chymosin has displaced small-scale, traditional cheesemakers who rely on natural fermentation processes.
• Potential Ecological Risks: Large-scale production of genetically modified enzymes requires industrial fermentation facilities that contribute to environmental concerns, including waste management and energy consumption.

Final Thoughts: The Need for Transparency in Food Labeling

The fact that 90% of U.S. cheese contains a genetically modified enzyme—without consumer disclosure—is a major food industry issue. Whether or not one believes GMO chymosin is harmful, the real problem lies in the lack of informed consent. People deserve the right to know what they are consuming, and current labeling laws do not support this right.

For those looking to opt out of the GMO cheese system, choosing organic, non-GMO verified, or artisanal cheeses can help avoid genetically modified enzymes. As consumer awareness grows, demand for greater transparency in food labeling may eventually push regulators and manufacturers toward more honest and ethical food production practices.

In the meantime, spreading awareness about hidden GMO ingredients is crucial. By educating ourselves and others, we can make more informed choices about the foods we eat and advocate for a food system that prioritizes transparency, quality, and consumer rights.
