Does 'Vaginal Seeding' Work? Doctors Say There's Not Enough Evidence


People will do just about anything for their kids. And for some parents of babies born by Caesarean section, that includes swabbing a baby with bacteria from their mother’s vagina. It’s a new idea, but it’s catching on—despite the fact that there’s no evidence that it helps, as several doctors note in the British Medical Journal (BMJ). 

The practice is called “vaginal seeding,” and aims to bolster a newborn’s health with the helpful starter bacteria he or she might have missed by skipping the birth canal. Microbiome is the collective term for the ecosystems of bacteria, fungi, and viruses living on and in your body. As you’ve probably heard by now, not all microbes are bad. In fact, you need a certain diversity and balance of microbes to keep your body functioning. You pick up these microbes everywhere you go, from the doorknob of a hotel room to kissing a friend on the cheek. Most people get their first microbial download as they enter the world. But C-section babies don’t. 

The concept seems sound enough. But, as the authors of the BMJ editorial explain, there’s simply no evidence that vaginal seeding is actually effective or safe.

"Demand for this process has increased among women attending hospitals in the UK—but this has outstripped professional awareness and guidance,” co-author Aubrey Cunnington said in a press statement. “At the moment we're a long way from having the evidence base to recommend this practice. There is simply no evidence to suggest it has benefits—and it may carry potential risks." 

Swabbing a baby transfers all kinds of microbes, both harmful and helpful. And since there’s no catalog of which bacteria are being shared, there’s no way of knowing which pathogens might be causing a baby’s sickness down the line. 

"In some countries, including the UK, we don't test pregnant women for the bacteria group B streptococcus,” Cunnington continued. “This is carried by around one in four pregnant women, and although it poses no risk to the mother, it can cause fatal infections in babies. There are also other conditions that cause no symptoms in the mother, such as chlamydia, gonorrhea, and herpes simplex virus that could be transferred on the swab. One colleague had to intervene when a mother with genital herpes, who had undergone a Caesarean section, was about to undertake this process. Swabbing would have potentially transferred the herpes virus to the baby." 

Hospital staff will also not expect a C-section baby to be vulnerable to the kinds of infections as a baby born of vaginal delivery. “It's important [that] parents tell staff they have performed the procedure, so the healthcare team are aware the baby is at risk of the same infections as a baby born by vaginal delivery," Cunnington added.

The bottom line is that parents and physicians should wait for more data before whipping out the swabs. In the meantime, Cunnington says, they can focus on evidence-based methods of boosting a baby’s microbiome: "Encouraging breast feeding and avoiding unnecessary antibiotics may be more important to a baby's gut bacteria than worrying about transferring vaginal fluid on a swab."

Visit Any National Park for Free on September 28—or Volunteer to Help Maintain Them

By the end of September—which always seems especially busy, even if you’re not a student anymore—you might be ready for a small break from the hustle and bustle. On Saturday, September 28, you can bask in the tranquility of any national park for free, as part of National Public Lands Day.

According to the National Park Service, the holiday has been held on the fourth Saturday of every September since 1994, and it’s also the nation’s largest single-day volunteer effort. It’s up to you whether you’d like to partake in the service side or simply go for a stroll, but there is an added incentive to volunteer: You’ll get a one-day park pass that you can use for free park entry on a different day. Opportunities for volunteering include trail restoration, invasive plant removal, park cleanups, and more; you can see the details and filter by park, state, and/or type of event here.

If you’re not sure how you should celebrate National Public Lands Day, the National Park Service has created a handy flowchart to help you choose the best course of action for you—which might be as simple as sharing your favorite outdoor activity on social media with the hashtag #NPLD.

There are more than 400 areas run by the National Park Service across the U.S., and many of them aren’t parks in the traditional sense of the word; the Statue of Liberty, Alcatraz Island, and countless other monuments and historical sites are also run by the NPS. Wondering if there might be one closer than you thought? Explore parks in your area on this interactive map.

For those of you who can’t take advantage of the free admission on September 28, the National Park Service will also waive all entrance fees for Veteran’s Day on November 11.

And, if you’re wishing a free-admission day existed for museums, you’re in luck—more than 1500 museums will be free to visit on Museum Day, which happens to be this Saturday.

General Mills Is Recalling More Than 600,000 Pounds of Gold Medal Flour Over E. Coli Risk

The FDA recently shared news of a 2019 product recall that could impact home bakers. As CNN reports, General Mills is voluntarily recalling 600,000 pounds of its Gold Medal Unbleached All-Purpose Flour due to a possible E. coli contamination.

The decision to pull the flour from shelves was made after a routine test of the 5-pound bags. According to a company statement, "the potential presence of E. coli O26" was found in the sample, and even though no illnesses have been connected to Gold Medal flour, General Mills is recalling it to be safe.

Escherichia coli O26 is a dangerous strain of the E. coli bacterium that's often spread through commercially processed foods. Symptoms include abdominal cramps and diarrhea. Most patients recover within a week, but in people with vulnerable immune systems like young children and seniors, the complications can be deadly.

To avoid the potentially contaminated batch, look for Gold Medal flour bags with a "better if used by" date of September 6, 2020 and the package UPC 016000 196100. All other products sold under the Gold Medal label are safe to consume.

Whether or not the flour in your pantry is affected, the recall is a good reminder that consuming raw flour can be just as harmful as eating raw eggs. So when you're baking cookies, resist having a taste until after they come out of the oven—or indulge in one of the many edible cookie dough products on the market instead.
