Cheese is as old as modern mankind, with clues about its existence reaching all the way back to 8,000 BC when the first sheep and goats were domesticated by our ancestors (www.historyofcheese.com). And since cheese has been around for so long, it is now one of the most popular and beloved foods throughout the world. So, it did not come as a surprise to me that many who are pregnant and breastfeeding ask MotherToBaby about eating cheese all the time! On our texting service alone (855-999-3525), we have received over 400 questions about cheese in the past few years!

Here are some of the recent questions we have received at MotherToBaby:

• “Am I allowed to eat cream cheese on toast?”
• “Is raw milk cheese from the USA OK?”
• “Can I eat goat cheese while breastfeeding?”
• “Is it OK to eat feta cheese during pregnancy?”
• “Can I continue to eat queso cheese on a burrito or nachos while pregnant?”
• “Is unpasteurized cheese OK to eat if it’s been cooked on a pizza?”

When you start researching cheese, you can fall into a rabbit hole on kinds of cheese: hard versus soft, pasteurized or not, Mexican verses Italian? The questions are endless. There are over 1800 different kinds of cheese, divided into 7 categories (www.Funtrivia.com):

1. Fresh Cheeses: Banon, Ricotta, Feta, Cottage cheese, Cream cheese, etc.
2. Natural Rind: Sancerre, Chabichou, Crottin de Chavignol, etc.
3. Soft White Cheese: Camembert, Brie, Chevre Log, etc.
4. Semi-Soft: Edam, Pont L’Eveque, St Nectaire, Tomme de Savoie, Langres, Carre de L’Est, Epoisses, etc.
5. Hard Cheeses: Cheddar, Parmigiano Reggiano, Gruyere, Manchego, etc.
6. Blue Cheeses: Stilton, Roquefort, Gorgonzola, Maytag Blue, Cashel Blue, etc.
7. Flavored Cheeses: Cornish Yarg, Gouda with Cumin, Stilton with Apricots, Devon Garland, etc.

So, what is the bottom line for you if you are pregnant or breastfeeding?

First, check to see if the cheese has been pasteurized or not. Look at the label and you will find that most types of packaged cheese or cheese products sold in America have been pasteurized or heat treated. Pasteurization is defined as a process in which both packaged and non-packaged foods (such as cheese and milk) are treated with moderate heat, usually up to 212 °F, to eliminate pathogens and extend shelf life. If the cheese has gone through pasteurization, then any increased risk for bacteria or other pathogens is very small, and the product isn’t considered to increase risks if eaten during pregnancy and breastfeeding. Of course, keep an eye on the fresh or sell-by date, and keep the product properly refrigerated. Cheese that has not been pasteurized has an increased risk for bacteria such as Listeria. See our fact sheet at Listeria Infection (Listeriosis) – MotherToBaby for more information. If the cheese has not been pasteurized, but has been cooked or heated prior to eating, then there also is little increased risk. Plus, cheese that has been dried, such as parmesan cheese, has a longer shelf life and no known increased risk for bacteria.

One of the most common questions about cheese when pregnant and breastfeeding is about the difference between hard and soft cheese. Hard cheese has been ripened longer and is drier, having a lower water content. Whereas soft cheese is younger or fresher, with a higher moisture content. The higher moisture content in soft cheese can allow for more growth of bacteria. That is why it is a good idea to be sure that soft cheeses are either heated prior to eating or have been pasteurized at the time of production (again, pasteurization is a process to kill bacteria). Most soft cheeses in the U.S. have undergone this process by FDA pasteurization law — so look at the label to be sure and be aware of any possible increased risks if unpasteurized!

Cheese is rich in protein and minerals such as calcium and phosphorus. During pregnancy and while breastfeeding, cheese can be part of your good diet. Some cheese types, such as hard cheese, are higher in fat. So, do watch the fat content if cheese is part of your daily diet! Just follow a few simple rules about checking for pasteurization and being sure the cheese product is heated or has been cooked prior to eating if it was not pasteurized. And then, enjoy eating cheese without worry during pregnancy and breastfeeding! If you have any cheese related questions during pregnancy, or any other exposure questions, be sure to contact MotherToBaby! We will be happy to help you!

I recently received a phone call from Molly.  Molly told me that she had just found out that she was pregnant; this was a surprise, but a welcome one.  However, Molly confessed that she smokes a pack of cigarettes per day and her doctor recommends that she quit smoking since cigarettes can present a number of hazards for her pregnancy and baby.  Molly’s friend told her that e-cigarettes were safe in pregnancy and would help Molly with her efforts to reduce use of traditional cigarettes.  Molly wanted to be sure.  “Don’t both cigarettes and e-cigarettes both contain nicotine,” she asked?  

What are e-cigarettes? 

‘E-cigarettes’ is short for electronic nicotine delivery system, sometimes also referred to as vapes, e-hookah, or other slang names.  E-cigarettes utilize a device that heats up nicotine-containing fluid from a cartridge, which can then be inhaled as a vapor.  Using an e-cigarette does have the potential to avoid some of the hazardous compounds found in traditional cigarettes such as tar and cadmium.  However, e-cigarettes are a relatively new product and not very well regulated.  Some e-cigarette fluids contain a lot of nicotine while others very little.  They often have other substances added to them including preservatives and flavorings. Many of these agents have not been studied regarding their safety in pregnant women.   

All of this makes it difficult to draw accurate conclusions about what risk e-cigarettes might present to a pregnant woman and her baby.  What we do know is that traditional cigarettes and nicotine (the chemical which is in both tobacco and e-cigarettes) do present a risk for a wide number of issues including birth defects (cleft lip and palate), miscarriage, and poor growth in the developing baby.  In addition, substituting e-cigarettes for traditional cigarettes is not a proven way to quit smoking, and in some cases, people continue to smoke conventional cigarettes as well as e-cigarettes which makes the exposure to the baby even larger.  Scientists are still learning about this, and most public health agencies recommend behavioral approaches as the safest strategy for pregnant women who are trying to quit smoking.

Molly is smart to ask about the safety of e-cigarettes before she uses them.  She also shows how much she cares about herself and her baby by trying to decrease smoking as much as possible!  I suggested she speak with her healthcare provider about strategies for quitting.  I also told her about free services like the CDC’s Smoker’s Quitline (1-800-784-8669).

What happens when a researcher studying pregnancy becomes a patient navigating her own autoimmune diagnosis? In this powerful episode of The MotherToBaby Podcast, genetic counselor Chris Stallman, CGC, sits down with Dr. Christina Longo, Assistant Professor at the University of Montreal and perinatal epidemiologist, to discuss her lived experience managing rheumatoid arthritis during pregnancy and breastfeeding.

Dr. Longo shares how her first diagnosis during pregnancy reshaped her research focus—from child outcomes to the importance of maternal health, mental wellbeing, and self-advocacy. She opens up about the difficult decisions she faced around medication safety, breastfeeding, and treatment during pregnancy, and how patient-led communities and research studies helped her find strength and clarity.

Listeners will learn:

• How autoimmune diseases can change during pregnancy and postpartum
• Why controlled treatment plans matter before conception
• The emotional and physical toll of navigating chronic illness while pregnant
• The importance of participating in pregnancy studies to improve care for future parents

Whether you’re living with a chronic condition, supporting someone who is, or counseling patients through pregnancy, this episode sheds light on the urgent need for research, empathy, and balanced care for both parent and baby.

How do public health experts detect emerging risks to pregnancies before they become widespread crises? In this episode of The MotherToBaby Podcast, host Chris Stallman, genetic counselor, mom of four, and teratogen information specialist, sits down with Dr. Amanda Elmore, Assistant Professor of Maternal & Child Health at the University of South Florida, to explore the powerful role of birth defect surveillance.

Dr. Elmore shares how her career in public health began during the Zika virus epidemic—reviewing medical records of exposed infants to help the CDC understand the real-world impact of in-utero exposure. She explains how surveillance systems track structural and functional birth anomalies, serve as early warning systems for new and emerging exposures, and shape everything from clinical care and referral services to national public health policy.

The conversation also dives into:

• How surveillance led to rapid public health responses during the Zika crisis
• What neonatal abstinence syndrome (NAS) reveals about opioid exposure during pregnancy
• The push for real-time data using electronic medical records and health information exchanges
• How machine learning and natural language processing may transform how cases are identified
• Why a life-course perspective matters for children born with birth defects
• How surveillance data supports funding, prevention efforts, and long-term family services

Dr. Elmore also shares her vision for the future: a more standardized, timely, and integrated national system that can better support prevention, research, and lifelong care for affected children and families.

This episode offers a behind-the-scenes look at how data quietly powers some of the most important protections for moms and babies.
