Cotija Cheese Production Process
Cotija cheese, a staple in Mexican cuisine, is traditionally made from raw cow’s milk, but modern variations often use pasteurized milk to meet safety standards. The production process begins with milk selection, where raw or pasteurized milk is heated to around 30°C (86°F) to prepare it for bacterial cultures. For raw milk, this step is critical as it retains natural enzymes and bacteria that contribute to the cheese’s distinct flavor. If pasteurized milk is used, specific lactic acid cultures are added to replicate the fermentation process. This initial heating and culturing phase sets the foundation for Cotija’s tangy, salty profile.
Next, rennet is added to coagulate the milk, forming curds and whey. The curds are then cut into small pieces and stirred to release moisture. Unlike softer cheeses, Cotija’s curds are cooked at a higher temperature, around 40°C (104°F), to achieve a firmer texture. After draining, the curds are pressed into molds and salted generously, either by brining or dry-salting. This salting step is crucial, as it not only preserves the cheese but also imparts the intense saltiness Cotija is known for. The cheese is then left to age, typically for three to twelve months, during which it hardens and develops its crumbly consistency.
Aging is where the pasteurization debate becomes most relevant. Traditional Cotija, made from raw milk, relies on natural aging to eliminate harmful bacteria over time. However, when pasteurized milk is used, the aging process is more controlled, often requiring additional steps to ensure safety. For instance, pasteurized Cotija may be aged in temperature-controlled environments to prevent contamination. Despite these differences, both versions aim to achieve the same end product: a hard, salty cheese ideal for grating over dishes like tacos or elote.
For home cheesemakers, replicating Cotija’s production process requires attention to detail. If using raw milk, ensure it is sourced from a reputable supplier to minimize health risks. When pasteurized milk is used, select high-quality lactic acid cultures to mimic traditional flavors. Pressing the curds for at least 24 hours and aging the cheese in a cool, dry place are essential steps. While pasteurized Cotija may lack some of the complexity of its raw milk counterpart, it remains a safe and accessible option for those wary of unpasteurized dairy.
In conclusion, the Cotija cheese production process hinges on milk selection, precise heating, and extensive aging. Whether made from raw or pasteurized milk, each step is designed to create a cheese that is both flavorful and functional. Understanding these nuances allows consumers to appreciate Cotija’s role in Mexican cuisine and make informed choices based on their preferences and safety concerns.

Pasteurization Requirements in Mexico
Mexican cheese production, including Cotija, operates under a regulatory framework that prioritizes food safety while preserving traditional methods. Unlike the United States, Mexico does not mandate universal pasteurization for all cheeses. Instead, its regulations focus on risk-based controls, allowing raw milk cheeses like Cotija to be produced legally under specific conditions. This approach reflects a balance between public health concerns and cultural preservation, as many traditional Mexican cheeses rely on raw milk for their distinctive flavors and textures.
To understand the pasteurization status of Mexican Cotija, it’s essential to examine the production process. Authentic Cotija is typically made from raw cow’s milk, aged for a minimum of 60 days. This extended aging period serves as a natural safety measure, as it reduces the risk of pathogenic bacteria. However, not all Cotija cheeses adhere to this traditional method. Some producers, particularly those exporting to the U.S., may use pasteurized milk to comply with FDA regulations, which prohibit the sale of raw milk cheeses aged less than 60 days.
For consumers, determining whether a specific Cotija cheese is pasteurized requires careful label scrutiny. Mexican regulations do not require explicit pasteurization labeling, so phrases like "made with pasteurized milk" or "raw milk" may not always appear. Instead, look for indicators such as aging duration or export certifications. For instance, Cotija labeled "aged over 60 days" is more likely to be made from raw milk, while products intended for international markets often use pasteurized milk to meet import standards.
Practical tips for consumers include purchasing Cotija from reputable sources and inquiring about production methods when buying from local markets or specialty stores. If pasteurization is a concern, opt for brands that explicitly state their use of pasteurized milk or choose aged varieties, which are safer due to their extended curing process. Pregnant individuals, the elderly, and those with weakened immune systems should exercise caution with raw milk cheeses, as they pose a higher risk of foodborne illnesses.
In summary, Mexico’s pasteurization requirements for cheeses like Cotija are flexible, prioritizing traditional practices while ensuring safety through aging and risk-based controls. Consumers must be proactive in verifying production methods, especially when purchasing outside Mexico, where export regulations may dictate pasteurization. By understanding these nuances, cheese enthusiasts can enjoy Cotija’s unique flavor profile while making informed choices aligned with their health needs.

FDA Regulations on Imported Cheese
The FDA mandates that all imported cheeses, including Mexican Cotija, must meet stringent pasteurization standards to ensure public safety. Specifically, the FDA requires that milk used in cheese production be pasteurized at a minimum temperature of 161°F (71.7°C) for at least 15 seconds, effectively eliminating harmful pathogens like *Listeria monocytogenes* and *Salmonella*. This regulation is codified under the Pasteurized Milk Ordinance (PMO), which serves as the benchmark for dairy safety in the United States. For Cotija cheese, a traditional Mexican product often made from raw milk, compliance with these standards is non-negotiable for entry into the U.S. market.
Analyzing the implications, the FDA’s pasteurization requirement poses a challenge for artisanal Cotija producers who rely on raw milk to achieve the cheese’s characteristic texture and flavor. However, it also safeguards consumers, particularly pregnant women, the elderly, and immunocompromised individuals, who are at higher risk from foodborne illnesses. To bridge this gap, some manufacturers now offer pasteurized versions of Cotija, labeled as "pasteurized process cheese" or "made from pasteurized milk," ensuring compliance while preserving cultural authenticity.
For consumers, verifying pasteurization is straightforward. Look for the phrase "made from pasteurized milk" on the label, as required by FDA regulations. Avoid products without this designation, especially when purchasing from international markets or specialty stores. Additionally, the FDA’s Food Safety and Inspection Service (FSIS) conducts random inspections of imported cheeses, providing an extra layer of assurance. If in doubt, contact the manufacturer directly or consult the FDA’s import refusal database for recent violations.
Comparatively, the FDA’s approach to imported cheese is stricter than that of some European countries, which permit the sale of raw milk cheeses under specific conditions. For instance, France allows raw milk cheeses with a minimum aging period of 60 days, deemed sufficient to reduce pathogen risk. In contrast, the U.S. prioritizes pasteurization regardless of aging, reflecting a zero-tolerance policy for potential hazards. This divergence highlights the importance of understanding regional regulations when sourcing or consuming imported cheeses.
In conclusion, the FDA’s regulations on imported cheese, particularly pasteurization requirements, are designed to protect public health without entirely sacrificing cultural food traditions. For Mexican Cotija cheese, this means adapting production methods to meet U.S. standards while retaining its unique qualities. Consumers can confidently enjoy pasteurized Cotija, knowing it complies with rigorous safety measures, while producers must navigate these regulations to access the U.S. market. Always verify labels and stay informed to make safe, informed choices.

Health Risks of Unpasteurized Cheese
Unpasteurized cheese, often celebrated for its rich flavor and artisanal quality, carries inherent health risks that cannot be overlooked. The pasteurization process eliminates harmful bacteria such as Listeria, Salmonella, and E. coli, which can thrive in raw milk products. Without this step, unpasteurized cheese becomes a potential vehicle for foodborne illnesses, particularly for vulnerable populations like pregnant women, young children, the elderly, and individuals with weakened immune systems. For instance, Listeria monocytogenes, commonly found in raw milk cheeses, can cause listeriosis, a severe infection with symptoms ranging from fever and muscle pain to miscarriages and neonatal infections.
Consider the case of Mexican Cotija cheese, a popular ingredient in many dishes. While some producers pasteurize their milk, traditional methods often involve raw milk, leaving consumers at risk. The U.S. Food and Drug Administration (FDA) advises against unpasteurized dairy products, especially for high-risk groups. Pregnant women, for example, are 10 times more likely to contract listeriosis, which can lead to premature delivery or stillbirth. To mitigate these risks, always check labels for "pasteurized" or "made with pasteurized milk" when purchasing Cotija or any cheese.
The risks extend beyond Listeria. Salmonella and E. coli outbreaks linked to unpasteurized cheese have been documented globally, causing symptoms like diarrhea, vomiting, and dehydration. These pathogens can be particularly dangerous for children under five, whose immune systems are still developing. A single serving of contaminated cheese can lead to severe illness, requiring hospitalization in some cases. For instance, a 2012 outbreak in the U.S. traced to raw milk cheese sickened 22 people across eight states, highlighting the far-reaching impact of such products.
Practical steps can reduce exposure to these risks. First, opt for pasteurized cheeses whenever possible, especially when cooking for vulnerable individuals. Second, store cheese properly—refrigerate at or below 40°F (4°C) to slow bacterial growth. Third, avoid consuming unpasteurized cheese if you fall into a high-risk category. For those who insist on raw milk cheeses, ensure the product is sourced from reputable producers with stringent hygiene practices. However, no amount of care guarantees safety, as bacteria can contaminate even the cleanest environments.
In conclusion, while unpasteurized cheese may offer unique flavors, its health risks are significant and well-documented. By understanding these dangers and taking proactive measures, consumers can enjoy cheese safely without compromising their well-being. Always prioritize pasteurized options, especially for Mexican Cotija cheese, and stay informed about the origins and production methods of the dairy products you consume.
