There's a most confusing advice about eating cheese when pregnant. We lay out the rules (and the risks).

You are watching: Is fresh mozzarella safe during pregnancy


I nothing remember what diet advice mine midwife offered when i was pregnant v my first daughter, however I plainly recall the directions my second time around. Maybe that’s because at the finish of the conventional “don’t consume” laundry perform (no booze, warm dogs, deli meat, or sushi) i was told not to eat unpasteurized cheese, “like soft cheese or blue or…well. Friend know.”

I wonder if ns was supposed to know due to the fact that I’d already had a kid, or since I to be a cheese expert. Adhering to that was the short consideration the I need to ask why unpasteurized cheese to be de facto a negative idea. However I stated nothing, instead imagining what every other pregnant woman was hearing and also how confused she need to be. It’s an ext than a small stressful once your health-care provider alerts of imminent doom to her unborn boy if girlfriend ate…“you know.”

The traditional laundry list of pregnant lady non-consumables comes from the Food and Drug management (FDA) and also United says Department of farming (USDA). Together, these groups ensure the safety of our nation’s food supply and execute federal legislations related come food. The American college of Obstetricians and Gynecologists agrees v their recommendations and so it is typical for ob-gyns, family members physicians, and also midwives to direct patients come avoid specific foods that can bear a higher risk for Listeria.

This greater risk is specifically why the FDA has really clear national laws around the production, importation, and sale that cheese: If a cheese is less than 60 work old, it need to be do of pasteurized milk. If a cheese is much more than 60 days old, specific varieties might be do of pasteurized or unpasteurized (often dubbed raw) milk, since the raw milk cheese has aged long sufficient to kill any kind of potential harmful bacteria.

Pasteurization is the process of heat-treating milk with the express purpose of ruining potentially harmful pathogens, such as Salmonella, that the milk might contain. FDA rules promulgated in 1949 figured out that must these pathogens be existing in milk, they passed away off in cheese during 60 job of aging, thus the 60-day dominion for cheese.

So what go this typical for united state cheese eaters? In the U.S., virtually all fresh (unaged, rindless) cheese—like mozzarella, fresh goat cheese/chèvre, ricotta, or feta—is pasteurized. The also way that 99 percent that soft, creamy, spreadable cheeses are pasteurized. Think Laughing Cow, Brie, Camembert, or Taleggio. Longer-aged cheese (which will be firmer in texture, potentially also hard, dry, or grainy) may or may not it is in pasteurized. Cheddar, Manchego, and also blue cheeses space readily available in both raw and pasteurized form.

These legal technicalities came to be deeply relevant when my job as cheese-guide way helping a pregnant mrs navigate a counter with 300-plus cheeses. What need to she get? what’s safe? and also here, things get a bit an ext complicated. Because, that course.

Standard medical advice speak you to stop unpasteurized cheeses and stick solely to the pasteurized ones. Yet given the 60-day rule, the pasteurized selections will it is in disproportionately soft cheeses, as in, the ones that part doctors indicate pregnant ladies to avoid. Soft cheeses are soft (and by U.S. Regulation pasteurized) precisely since they room younger and greater in moisture. Microbiologically, soft cheese are an ext hospitable environments for pathogens (like Listeria) 보다 hard, dried cheeses. Bacteria need moisture come grow. They additionally thrive in short acid and also low salt environments, which is specifically the condition of most pasteurized cheeses in the U.S.

The other thing to consider around cheese is that, also when pasteurized, that can end up being contaminated through Listeria (or Salmonella or other pathogens) after that is made. An additional contamination is a risk that can occur farther down the it is provided chain. Take into consideration two very common circumstances: cheese sliced at a supermarket deli counter, or cheese reduced at a sleeve counter. In one of two people case, deli meat or one more cheese that may be contaminated v harmful pathogens can spread bacteria v surprising effectiveness if machinery or worker sanitation isn’t rigorously maintained.

Before falling down the scary-food hare hole and concluding the the ideal answer is to eat nothing however air and purified water, let me re-superstructure the perspective of Dr. Catherine Donnelly, Professor at the university of Vermont, and also an professional on the microbiological safety of food (with a details focus top top Listeria monocytogenes): “Swiss-style difficult cheeses and Italian-style grana cheese have been determined by Food requirements Australia brand-new Zealand to have equivalent safety to cheese made from pasteurized milk, also though they room all life milk cheeses.” It’s precious noting, too, that both Australia and new Zealand prohibit the import or revenue of almost all unpasteurized cheeses, nevertheless of age, therefore they’re not precisely lax ~ above this topic. The hard cheeses listed by Dr. Donnelly have the combined effects of lack of moisture, high acidity, and also high salt contents that create, as she explains it, “a hurdle result where pathogens can’t prosper in the cheese or survive if they’re current in the an initial place.”

Another beneficial tip to think about for females craving soft, buttery cheese is to buy individual ring of pasteurized cheese fairly than piece that have actually been cut from a larger wheel. These bring no threat of cross-contamination from cutting at the cheese counter. Look because that mainstream Brie and also Camembert brands obtainable in eight- or nine-ounce rounds, prefer La Bonne Vie, Le Châtelain, or Président; or American artisan offerings choose Jasper Hill Farm’s Harbison or Sweet Grass Dairy’s environment-friendly Hill.

As Dr. Katherine McCleary, Clinical Assistant Professor of household Medicine in ~ Brown university Warren Alpert medical School summarized, “Everything we execute carries a little bit of threat so these decisions are eventually personal.” I find it much easier to make a confident decision when I’m totally informed. So, to recap:

The standard medical advice is to protect against all unpasteurized (a.k.a. Raw milk) cheese.However, creamy, high-moisture cheese (most that which are pasteurized) space microbiologically much more hospitable to harbor or grow pathogens choose ListeriaHard, dry, acidic, braided cheeses (that can be unpasteurized but aged because that well end 60 days) are much less likely come harbor or thrive pathogens like Listeria.There are several aged pasteurized cheeses if you desire to be doubly careful. Look for Aged Gouda (Beemster, Parrano, Prima Donna, or Reypenaer are all an excellent brands), cheddar (Cabot Clothbound, Dubliner, Excalibur, or Old Croc space all great and conveniently available), Manchego, Parmesan (not Parmigiano- Reggiano), or Piave.But also these space not immune to the dangers of cross-contamination; totality intact cheeses are.

With this in mind, happy eating! High in fat and also protein and rich in many nutrients other than vitamin C and also fiber, cheese is just one of the ideal one-stop sources of nutrition the end there. And also if you’re favor me, cheese comes in handy throughout a nine-month aversion come meat.
