The Short Answer: Yes, But With Caveats
Yes, Costco does sell some raw cheese, but it is not a widespread feature of their cheese selection. The vast majority of their cheese products, especially Kirkland Signature brand items, are made with pasteurized milk. Any raw milk cheese you find at Costco will almost certainly be an aged, imported variety that complies with U.S. federal regulations requiring raw milk cheese to be aged for a minimum of 60 days. This aging process significantly reduces the risk of harmful bacteria. Availability can fluctuate based on the specific warehouse location and current inventory.
Understanding Raw vs. Pasteurized Cheese at Costco
The key difference between raw and pasteurized cheese is the milk used in its production. Raw milk is unheated, while pasteurized milk is heated to a high temperature to kill any potential pathogens. Most cheeses on the market are made from pasteurized milk, which is considered the safest option, especially for pregnant individuals, children, and those with weakened immune systems. Costco's commitment to food safety is paramount, and its house brand cheeses reflect this by using pasteurized milk. However, their extensive international selection opens the door for aged, imported raw cheese varieties.
Where to Find Raw Cheese at Costco
If you are searching for raw cheese, you should focus your attention on the specialty and imported cheese sections. These are typically where you will find the products that fit the aged, raw milk criteria. Some of the raw milk varieties you might encounter include:
- Parmigiano Reggiano: Authentic Parmigiano Reggiano from Italy is made with raw milk and is aged for a minimum of 12 months, far exceeding the 60-day rule.
- Gruyère: Genuine Gruyère AOP from Switzerland is another raw milk cheese that is aged for several months.
- Comté: French Comté, a firm, raw milk cheese, can also be found in some locations.
- Manchego: Some versions of this Spanish cheese are made with raw milk, especially if aged over 60 days.
How to Verify if a Cheese is Raw
To be sure you're buying a raw cheese, you should:
- Check the label: Always read the ingredients list. Cheeses made with pasteurized milk will almost always state "pasteurized milk".
- Look for the aging period: The package for raw cheese should mention an aging period, typically over 60 days, to comply with regulations.
- Research the brand: If the label is unclear, research the specific brand and type of cheese online to confirm its production process.

Food Safety and Costco Standards
Costco is well-regarded for its stringent food safety standards, which apply to all products sold in its warehouses. All suppliers, including cheese manufacturers, must comply with exacting standards and undergo regular audits. While this is a priority, it does not preclude the sale of legally compliant raw milk cheese, especially high-quality imported varieties. The combination of Costco's quality control and the 60-day aging requirement for imported raw cheeses ensures a safe product for consumers. You can find more details about their supplier requirements on their corporate website.
Conclusion: Navigating the Cheese Aisle
In conclusion, while the vast majority of cheese at Costco is pasteurized, savvy shoppers can find raw cheese options among the imported, hard varieties. To find them, focus on international cheese sections and always verify the product's ingredients and origin. The aging process, mandated by law, makes these specific raw cheeses safe for most consumers, but those with health concerns should stick to pasteurized products. With this knowledge, you can confidently explore Costco's diverse cheese selection to find exactly what you're looking for. The journey through the Costco cheese aisle offers a delicious lesson in cheese production and global food standards.

Making an Informed Choice: Is Raw Cheese for You?
Choosing between raw and pasteurized cheese often comes down to personal preference for flavor, texture, and individual health considerations.

It’s important to remember that even within the raw cheese category, there is a wide range of flavor profiles and aging processes. By understanding the basics and reading labels carefully, you can make the best choice for your tastes and needs.
