What is Cotija Cheese?
Cotija cheese, a staple in Mexican cuisine, is a hard, crumbly cheese known for its salty, tangy flavor. It is often used as a topping for tacos, salads, and soups, adding a burst of umami that elevates any dish. But what exactly is Cotija cheese, and how does it fit into the conversation about pasteurization? To understand this, let’s break down its origins, production process, and common uses, while addressing the pasteurization question directly.
Origins and Production:
Cotija cheese hails from the town of Cotija in Michoacán, Mexico, where it has been crafted for centuries using traditional methods. Traditionally, it is made from raw cow’s milk, which is curdled with rennet and then pressed to remove excess whey. The cheese is aged for at least three months, during which it hardens and develops its distinctive flavor profile. However, modern production often involves pasteurized milk to comply with food safety regulations, particularly in the U.S. and other countries. This shift raises the question: is the Cotija cheese you’re buying pasteurized? The answer depends on the brand and region, but many commercially available varieties are indeed made with pasteurized milk to ensure safety and extend shelf life.
Texture and Flavor:
Cotija’s texture is its defining characteristic—firm yet brittle, allowing it to be crumbled or grated with ease. Its flavor is bold and salty, with a slight nuttiness that complements both savory and spicy dishes. When made with raw milk, Cotija may have a more complex, earthy taste due to the natural bacteria present. Pasteurized versions, while still flavorful, tend to be milder and more consistent in taste. For those seeking authenticity, traditional raw milk Cotija is ideal, but it’s crucial to source it from reputable producers to minimize health risks.
Practical Tips for Use:
Incorporate Cotija into your cooking by sprinkling it over tacos, enchiladas, or elote (Mexican street corn). Its salty kick also pairs well with fresh vegetables like avocado or tomatoes. If you’re unsure whether your Cotija is pasteurized, check the label—most brands will indicate this clearly. Pregnant individuals or those with weakened immune systems should opt for pasteurized Cotija to avoid potential risks associated with raw milk products. For storage, keep it refrigerated and use within a few weeks to maintain freshness.
Takeaway:
Cotija cheese is more than just a topping—it’s a cultural icon with a rich history and versatile applications. Whether made with raw or pasteurized milk, its unique texture and flavor make it indispensable in Mexican cuisine. When choosing Cotija, consider your preferences and safety needs. Pasteurized versions offer convenience and peace of mind, while traditional raw milk varieties provide an authentic experience. Either way, Cotija cheese is a must-have ingredient for anyone looking to add depth and character to their dishes.

Pasteurization Process in Cheese Making
The pasteurization process is a critical step in cheese making, designed to eliminate harmful bacteria while preserving the milk’s essential qualities. During pasteurization, milk is heated to a specific temperature for a defined duration to kill pathogens like *Salmonella*, *E. coli*, and *Listeria*. For example, the most common method, high-temperature short-time (HTST) pasteurization, involves heating milk to 72°C (161°F) for 15 seconds. This process ensures safety without significantly altering the milk’s flavor or nutritional profile, making it ideal for cheeses like Cotija, where texture and taste are paramount.
In the context of Cotija cheese, pasteurization plays a dual role: ensuring safety and meeting regulatory standards. Traditional Cotija, a Mexican cheese, was historically made with raw milk, but modern production often uses pasteurized milk to comply with food safety laws. The pasteurization process must be carefully controlled to avoid denaturing proteins or altering the milk’s ability to curdle properly. For instance, overheating can lead to a grainy texture in the final cheese, while insufficient heat may leave harmful bacteria intact. Cheese makers must balance precision and tradition to maintain Cotija’s characteristic crumbly, salty profile.
From a practical standpoint, home cheese makers should note that pasteurizing milk for Cotija requires a food thermometer and vigilance. Heat the milk to 63°C (145°F) and hold it there for 30 minutes, then cool it rapidly to 32°C (90°F) for culturing. This method, known as vat pasteurization, is more time-consuming than HTST but is feasible for small batches. Always use a reliable thermometer to monitor temperatures, as even slight deviations can affect the outcome. For those purchasing Cotija, check labels for "made with pasteurized milk" to ensure compliance with safety standards.
Comparatively, pasteurized Cotija differs subtly from its raw milk counterpart. While pasteurization eliminates the risk of foodborne illness, it may slightly mute the cheese’s complex flavors, which raw milk enthusiasts prize. However, the difference is often minimal, especially in aged Cotija, where the sharp, salty notes dominate. For pregnant individuals, children, or immunocompromised persons, pasteurized Cotija is a safer choice, as raw milk cheeses can pose health risks. Ultimately, pasteurization ensures Cotija remains a versatile, widely accessible ingredient without compromising its culinary appeal.

Health Risks of Unpasteurized Cheese
Unpasteurized cheese, often celebrated for its rich flavors and artisanal appeal, carries inherent health risks that cannot be overlooked. The primary concern lies in the potential presence of harmful bacteria, such as *Listeria monocytogenes*, *Salmonella*, *E. coli*, and *Campylobacter*. These pathogens can thrive in raw milk products, leading to foodborne illnesses that range from mild gastrointestinal discomfort to severe, life-threatening conditions. For instance, *Listeria* infections can cause miscarriages in pregnant women and meningitis in individuals with weakened immune systems. Understanding these risks is crucial for anyone considering consuming unpasteurized cheese, including varieties like cotija, which may or may not be pasteurized depending on the producer.
Pregnant women, young children, the elderly, and immunocompromised individuals are particularly vulnerable to the dangers of unpasteurized cheese. The CDC advises these groups to avoid such products entirely due to their heightened susceptibility to infections. For example, a *Listeria* outbreak linked to unpasteurized queso fresco in 2017 resulted in 22 hospitalizations and two fetal losses. Even healthy adults are not immune; *E. coli* O157:H7, commonly found in raw milk products, can cause hemolytic uremic syndrome (HUS), a severe complication affecting the kidneys. These statistics underscore the importance of verifying whether cheeses like cotija are pasteurized before consumption.
The pasteurization process, which involves heating milk to a specific temperature to kill harmful bacteria, significantly reduces these risks. However, some traditional cheeses, including certain cotija varieties, are made with raw milk to preserve their unique texture and flavor. Consumers must carefully read labels or inquire about production methods to ensure safety. For instance, Mexican-style cotija sold in the U.S. is often pasteurized to comply with FDA regulations, but artisanal or imported versions may not be. When in doubt, opt for pasteurized alternatives or avoid raw milk cheeses altogether, especially in high-risk populations.
Practical steps can mitigate the risks associated with unpasteurized cheese. Always store cheese at or below 40°F (4°C) to slow bacterial growth, and consume it promptly after opening. If preparing dishes like salads or tacos with cotija, ensure other ingredients are handled safely to prevent cross-contamination. For those who enjoy the authenticity of raw milk cheeses, consider purchasing from reputable producers who adhere to strict hygiene standards. However, no precaution can entirely eliminate the risk, making pasteurized options the safer choice for vulnerable individuals. Balancing culinary preferences with health considerations is key to enjoying cheese without compromising well-being.

How to Check if Cotija is Pasteurized
Cotija cheese, a staple in Mexican cuisine, often leaves consumers wondering about its pasteurization status. To determine if your Cotija is pasteurized, start by examining the packaging. Most commercially produced Cotija cheeses in the U.S. are made with pasteurized milk to comply with FDA regulations, which require aging cheeses made from raw milk to be aged for at least 60 days. Look for terms like "made with pasteurized milk" or "pasteurized" on the label. If the packaging lacks this information, the cheese is likely pasteurized, but contacting the manufacturer for confirmation is advisable.
If you’re purchasing Cotija from a local market or specialty shop, the situation may differ. Artisanal or imported Cotija cheeses are more likely to be made with raw milk, especially if they come from regions with traditional production methods. In such cases, inquire directly with the vendor or check for certifications on the product. Raw milk Cotija will often have a more complex flavor profile, but it carries a higher risk for pregnant individuals, the elderly, or those with weakened immune systems due to potential bacterial contamination.
Another practical approach is to consider the cheese’s texture and appearance, though this method is less definitive. Pasteurized Cotija tends to be slightly softer and more uniform in texture compared to its raw milk counterpart, which may have a drier, crumbly consistency. However, these differences are subtle and not reliable indicators on their own. Always prioritize label information or direct communication with the producer over visual cues.
For those who prioritize safety, especially in recipes like salads or salsas where Cotija is consumed raw, opting for pasteurized versions is recommended. If you’re unsure, err on the side of caution and choose a brand that explicitly states its pasteurization status. While raw milk Cotija offers a unique culinary experience, the potential health risks make pasteurized options a safer choice for most consumers. Always store Cotija properly—refrigerated and wrapped in wax paper or cheesecloth—to maintain its quality and safety, regardless of its pasteurization status.
