Are We Over-Sanitizing?

Apr 9, 2021

The days of wiping down groceries may be coming to an end, but will Americans' reliance on hand sanitizer follow suit?


This week, the Centers for Disease Control and Prevention (CDC) released a report confirming that the risk of catching the coronavirus from surfaces is low. Kevin Minbiole, PhD, chair of the Department of Chemistry at Villanova University, weighs in on hand sanitizer use—and whether too much sanitizing is a bad thing.


"I think that a lot of the concern on the overuse of hand sanitizer a decade ago or so was the overuse of triclosan, a strong antimicrobial agent that would persist in wastewater," said Dr. Minbiole, referring to a theory that arose following the H1N1 pandemic in 2009. At that time, scientists expressed worry that bacteria were becoming resistant to hand sanitizer. "It seemed like overkill to go beyond soap and water or simply ethanol (alcohol)—or to add triclosan into hand soap," Dr. Minbiole continued.


While Dr. Minbiole does not dismiss this theory, he notes, "I believe there was merit to the concerns of overapplying antibiotics and antiseptics when they were not needed."


Looking to the future, Dr. Minbiole does not see hand sanitizer playing as big a role. "I don't foresee a backlash so much here, as folks recognize that this particular virus is more of an airborne concern," he says.

Sport and Study: Villanova University Faculty Offer Academic Lens to Paris Olympics Storylines

All eyes are on Paris: more than 10,000 athletes from 206 nations are set to compete in the Games of the XXXIII Olympiad, the third Olympics in the City of Love and the first since 1924. Below, Villanova University faculty members provide their academic expertise on the unique storylines and narratives already taking place as Paris 2024 gets underway. Portraying a National Image in the Opening Ceremony Étienne Achille, PhD Director of French and Francophone Studies After months of speculation, the daily Le Parisien has officially confirmed that renowned French-Malian singer Aya Nakamura will lend her vocals to an opening ceremony featuring an iconic backdrop steeped in history. “Nakamura is the most-streamed Francophone singer in the world, embodying France’s culture on a global stage, and she’ll be paying homage to one of the most cherished representatives of the chanson française,” said Dr. Achille, referring to reports she will sing one of beloved French crooner Charles Aznavour’s greatest hits. According to Dr. Achille, the pop star’s presence is significant and symbolic. “A performer, or even a flagbearer, can easily become the face of a global event like the Olympics,” he said. The details of the setting for the ceremony – in the heart of Paris, along the Seine – are just as intentionally symbolic. “Not only will this be the first opening ceremony to take place entirely outside of a stadium; its location along the river and the fact the delegations will be on boats are key. “It represents movement and connection to the world,” Dr. Achille said. “And Nakamura’s performance projects the image of a modern, multi-ethnic nation building on tradition while proudly marching into the future.” Swimming in the Seine: Safe or Not? Metin Duran, PhD Professor of Civil and Environmental Engineering It is, perhaps, the most-asked question of the last few weeks. Is the Seine River, set to host multiple swimming events, safe? The river has been illegal to swim in for a century due to the presence of harmful bacteria such as E. Coli, and recent testing has reaffirmed this concern. The Seine, which had undergone an expensive cleaning to mitigate this issue, received the endorsement of Paris Mayor Ann Hidalgo, who personally took a dip in the water herself to attest to its safety. The stunt did little to convince experts such as Dr. Duran, who studies wastewater, to abandon concern about the potential health risks of athletes being exposed to pathogens in the water. “When we have fecal pollution, there is a high likelihood of pathogens being present,” Dr. Duran said. “Those could be viral, like a norovirus, or protozoan. “If you’re swimming in that water, you run the risk of ingesting it. Once you ingest that polluted water, you’re likely to contract some of those disease-causing pathogens. Ingesting this water doesn’t mean you’re necessarily going to get sick, but based on the number of people in a big city like Paris, there is a very high likelihood of some of these pathogens existing now in the river.” Accommodations for Breastfeeding Athletes Sunny Hallowell, PhD, APRN, PPCNP-BC Associate Professor of Nursing The IOC and Paris 2024 Organizing Committee is providing support to all breastfeeding athletes competing in the Games. A few national governing bodies, like the French Olympic Committee, are going a step further and offering hotel rooms near the Village for their country’s breastfeeding athletes to share with their children and spouses. “A few decades ago, the idea of a female athlete who also wanted to breastfeed their child was so taboo it may have prevented an athlete from competing,” said Dr. Hallowell. “Now, many female athletes who choose to breastfeed their newborns or toddlers conceptualize breastfeeding as another normal function of their remarkably athletic bodies.” Accommodation for breastfeeding athletes and increased awareness are needed more than ever. Dr. Hallowell notes that in addition to changing views on breastfeeding, the needs for such accommodations are increasing as the age of peak athletic performance also increases. “Advances in sports nutrition, wellness and lifestyle have extended the longevity and performance of many athletes into adulthood,” she said. And while some athletes with rigorous training regimens might feel “frustrated incorporating breastfeeding into the routine,” Dr. Hallowell says that for others, “breastfeeding provides both physical and socio-emotional benefits for the mother and the infant that allow the athlete to focus on the job of competition.” Protecting Against the Parisian Heat Ruth McDermott-Levy, PhD, MPH, RN, FAAN Professor of Nursing The potential for extreme heat in Paris has been a topic of concern for athletes and organizers, prompting certain outdoor events to be proactively scheduled at times to avoid the day’s worst heat. Current forecasts predict temperatures in the 90s for several days early on in the Games, which could be exacerbated by Paris’ reputation as an urban heat island, unable to cool due to lack of green space and building density. Dr. McDermott-Levy says the athletes are inherently vulnerable, because “the added stress of physical exertion during their events puts them at greater risk of heat-related illness.” But she also notes that many of the athletes have likely undergone pre-competition training in extreme heat conditions to acclimate and will have trainers and health professionals monitoring them frequently. “The group of concern are the workers at the stadiums, outdoor workers and spectators who are there to enjoy or work at the events and may have had little to no acclimation,” Dr. McDermott-Levy said. “They need to follow local instructions and take frequent breaks from the heat, seek shade and maintain hydration by avoiding alcohol and sugary drinks and drinking water.” How Nature Can Inspire Future Use of Olympic Infrastructure Alyssa Stark, PhD Assistant Professor of Biology Gone, hopefully, are the days of abandoned Olympic Villages and venues, overrun with weeds and rendered useless soon after the Games conclude. The IOC’s commitment to sustainability has been transparently relayed ahead of the 2024 Games, featuring a robust range of initiatives and programs. Dr. Stark is particularly interested in one aspect of ensuring a sustainable Olympics. “How will the structures, materials and systems they developed for the Olympics be re-used, re-shaped or re-worked afterward?” she posed. “This could include re-using buildings to larger scale or re-working transportation systems set in place for the Games that could then integrate into day-to-day life post Olympics.” At the root of her interest is the concept of biomimicry. “A lot of the way we think about designing, if we’re using this biomimicry lens, is how do we learn from nature to solve problems that we have in a sustainable way, keeping in mind the environment we are in?” Dr. Stark said. In this case, consider how something like a dwelling of a living creature might be repurposed to fit the needs of another creature, or serve another natural purpose, without harming the ecosystem. Could that inspire a way to re-use the Olympic infrastructure? “There are a ton of examples of [biomimicry] being used and working in products,” Dr. Stark said. “But I would say the next step is looking at the social levels of these big ecosystems – building architecture, city planning, flow of information and, in this instance, repurposing what was created for the Olympics.” Paris Could Be a Transportation Model for Major City Events in the United States Arash Tavakoli, PhD Professor of Civil and Environmental Engineering Paris has invested 250 million Euro the last several years to transform the city to a 100% cycling city, making it one of the most bike-friendly municipalities in the world. Currently, more trips are being made by bicycles in Paris than by cars (11% vs. 4%), a trend that has permeated to the surrounding suburbs as well. With an influx of travelers in Paris for the Games, Dr. Tavakoli, an expert in human transportation, said, “The Olympics will be a test for how well these kinds of systems respond to high fluctuations in the population as compared to vehicle-centric systems.” While Paris is thousands of miles away from the United States, how bicycle, pedestrian and vehicle systems work during the Games could provide helpful insight ahead of major events in American cities. “With the World Cup coming to the U.S. in a few years, it will be interesting to compare [Paris] with how our own system responds to people’s needs,” Dr. Tavakoli said. “Not just based on traffic data and congestion, but also considering factors like how comfortable the transportation system is, how much it affects our well-being and how much it attracts a nonresident to enjoy the U.S. when their only option, for the most part, is a vehicle.”

Cosmetic or Drug? The FDA’s Classification of Sunscreen Limits Which Products Hit US Shelves

As stifling rays of sunshine beat down across the United States, it’s the time of year citizens flock to the store to load up on sun protection. It’s also the time of year consumers and media raise the annual question of why Europe is able to market sunscreen that contains more potentially effective ingredients, but the U.S. isn’t. The answer is not related to sunscreen or its ingredients, but rather how the country’s regulatory body – The Food and Drug Administration (FDA) – legally operates. “In order for the FDA to legally regulate products, those products are given classifying labels,” said Ana Santos Rutschman, a professor of law at Villanova University who studies health law. “A toothbrush, for instance, is labeled a medical device. That’s because it has to fit in one of the sources of authority of the FDA and the FDA, per the law, regulates drugs or medical devices.” Here is where it gets tricky. The FDA does not have to approve cosmetics, aside from certain color additives, before those products go to market. In the European Union’s European Medicines Agency (EMA), sunscreen is labeled as a cosmetic. Many other countries also classify it as such. In the U.S., however, sunscreen is labeled a drug because it has a therapeutic effect, and thus falls under the authority of the FDA. To make the classification system even more convoluted, some items are labeled as both a cosmetic and drug by the FDA. Shampoo, for instance, is inherently cosmetic. “But if it’s anti-dandruff shampoo, then it’s also a pharmaceutical,” said Santos Rutschman. “It’s super common for this to happen with a lot of products that you and I would not think are classified as drugs. It’s very natural under the regulatory regime that we have, but then it is very hard to bring anything to market – harder than other countries.” Case in point, sunscreen used in the EU that contains ingredients which may be more effective against certain types of ultraviolet rays cannot simply just come to market in the U.S. “If sunscreen fits the definition of a drug, then it must meet drug requirements,” said Santos Rutschman. “If you want a new drug to enter the U.S., you have to show efficacy and safety. But in order to do that, there must be clinical trials, and if those trials happened elsewhere, they would not conform to our domestic protocols. “Even if another country performed their own clinical trials, the odds the FDA would utilize the data are not incredibly high. If you think another country recognizes something we should, based on their data, then immediately this is going to raise questions of why we are deferring to a foreign regulator.” The FDA could go through the process of approving ingredients in question – and has indicated it will do so – but it’s a complicated process, and there is “also a matter of risk,” according to Santos Rutschman. “The FDA has always been less risk averse than its counterparts in Europe. I understand the market concerns, but this seems about right from a regulatory perspective… We aren’t talking about a specific drug that people need and cannot access. Sunscreen is available for the average American to purchase.” Barring an overhaul to the regulatory system in the U.S. to include an agency for cosmetics – an idea some argue has merit, but Santos Rutschman described as “not feasible” with the available funding – the only way Europe’s sunscreen would be available for Americans to purchase is if the FDA moved forward in regulating the ingredients. And that will continue to take time. “The FDA has never moved quickly on anything,” said Santos Rutschman. “It just can't.”

The EPA Cracks Down on 'Forever Chemicals' in Drinking Water

For many years, toxic per- and polyfluoroalkyl substances (PFAS) have contaminated drinking water supplies across the United States. But in April, the Environmental Protection Agency (EPA) announced major steps to rein in these stubborn "forever chemicals." In a groundbreaking move, the EPA set strict new limits on six types of PFAS that are currently present in drinking water. Permitted levels of these chemicals are now close to zero, as water suppliers will be required to reduce them to the lowest level that can possibly be measured. These are the first-ever nationwide drinking water regulations for PFAS issued by the federal government. "The EPA is asking water companies to try to get PFAS levels to zero because there's no safe level. It's very difficult to test below four parts per trillion with the equipment and the testing mechanisms we have right now, so the levels will be reduced as much as they possibly can," said Dr. Laura Anderko, Co-director of the Mid-Atlantic Center for Children's Health and the Environment at Villanova University’s M. Louise Fitzpatrick College of Nursing. So what’s driving this urgency to minimize exposure to PFAS? Our children’s health is one big reason. As Dr. Anderko explains, "Children are more susceptible and vulnerable to the health impacts of PFAS because their bodies are still growing. Some of the health issues resulting from PFAS exposure are high cholesterol and a decrease in infant growth and fetal growth - so much so that there's a tendency towards low birth weight." Adults aren't spared either. PFAS has been linked to health issues including kidney cancer, liver problems and reduced antibody response from vaccines. For pregnant women, PFAS can increase the risk of high blood pressure. “These chemicals do impact pretty much every organ system of the body," Dr. Anderko said. With many different PFAS compounds used in products from fast food packaging to Band-Aids to carpeting, avoiding exposure to them can be difficult. Dr. Anderko’s advice to reduce exposure is to educate yourself on what products contain PFAS and purchase alternative options when possible. She also cautions against relying solely on bottled water, which isn't necessarily safer than tap water. "We have this idea that bottled water is safe because it's packaged, but a lot of times that water is not tested, and we know for a fact that bottled water is filled with microplastics,” she said. “You're better off not relying on bottled water unless you absolutely have to.” Per Dr. Anderko, in the United States chemicals can be inserted into some products without stringent testing for human health effects beforehand, so the EPA's new PFAS limits represent a major step toward putting human health first. While there is still a long road ahead to completely eliminate PFAS from our daily lives, these new regulations signal a welcome shift toward protecting public health in our country.
