Recent reports from the People’s News are raising concerns for families heading to the beach this summer. Several well-known beaches across the U.S. have shown higher levels of bacteria, and that means swimming and especially swallowing beach water could pose health risks for children.
In Massachusetts, officials have closed 19 beaches to the public due to the bacterial exceedance, says USA Today. These bacteria pose the risk of illness. Water quality problems can be dangerous even when beaches are open, especially for young children who are more likely to consume tainted water unintentionally.
Why Bacteria Are Tested at Beaches
When it comes to keeping our beaches safe, scientists often rely on something called indicator organisms. The Commonwealth of Massachusetts explains that these harmless microbes act as stand-ins for dangerous pathogens.
The germs that can cause illness in humans. It is challenging and time-consuming because it directly detects harmful pathogens in water. Indicator organisms are used as a practical way to tell if water might be contaminated, especially by fecal matter.
Scientists test for specific types of enteric bacteria to monitor water quality at public beaches. At marine (saltwater) beaches, Enterococci are the go-to indicator. For freshwater beaches, E. coli or Enterocci testing is done, depending on the location and local health department guidelines.
Public health officials can make informed decisions about beach closures by checking for these indicator organisms, which can help protect swimmers from getting sick.
Where Is It a Problem in Massachusetts This Summer
Over 1,100 public and semi-public beaches are monitored for water quality during the official swimming season. This monitoring focuses on detecting indicator bacteria that could signal harmful contamination, as state and federal regulations require.
Meanwhile, the 19 beaches were reported by USA Today, which include:
- Pomps Pond in Andover
- Damon Pond Beach in Ashby
- Upper Mill Pond in Brewster
- Walden Pond in Concord
- Sandy Beach in Danvers
- Kings in Lynn
- Magnolia and Tuck’s Point in Manchester
- Henry F Collins Beach in Marlborough
- Cochituate State Park Beach in Natick
- Long Beach in Rockport
- Children’s Island (Back and Walley) and Ocean Avenue in Salem
- Pekham Pond at Camp Nihan in Saugus
- Beaman’s Pond (Campground and Day Use) in Templeton
- Seth’s Pond in West Tisbury
- Shannon Beach at Upper Mystic in Winchester
Health Risks from Bacteria in Beach Water
Swimming in water with high bacteria levels can lead to health issues, some minor, others more serious. Most people just experience mild symptoms, but for kids, seniors, or anyone with a weaker immune system, the risk of complications is higher.
Common symptoms of waterborne illness are the following:
- Gastrointestinal Issues: nausea, vomiting, diarrhea, stomach cramps
- Respiratory Problems: sore throat, coughing, runny nose, sneezing
- Skin Irritation: rashes, redness, or itching
- Flu-like Symptoms: fever and chills
Even though these symptoms are usually minor and go away on their own, it’s important to avoid swimming in beach water that may be unsafe, especially during or after heavy rain, when bacteria levels can spike.
When to See a Healthcare Provider
Usually, these symptoms are mild and go away within a few days. But, there are times when medical attention is necessary. Parents need to know the warning signs that could indicate a more serious infection.
You should contact your child’s healthcare provider if they experience:
- Diarrhea lasting more than two days
- Signs of dehydration (dry mouth, dizziness, low energy, or fewer wet diapers)
- High fever (over 100.4 ℉ in infants or over 102 ℉ in older children)
- Vomiting that doesn’t stop or prevents your child from staying hydrated
- Redness, swelling, or pain around a cut or scrape after swimming
- Unusual fatigue, confusion, or difficulty waking up
In rare but serious cases, such as wound infection that worsens quickly, or symptoms of sepsis (like rapid heart rate, low blood pressure, or chills), seek urgent care immediately.
When unsure, it’s always safer to check with a healthcare provider; better safe than sorry. Early evaluation or treatment can make a big difference, especially with fast-moving infections.
