Biloxi, Mississippi — Beachgoers planning to visit the Mississippi Gulf Coast are being urged to use caution after state officials issued multiple water advisories due to elevated bacteria levels detected at several popular beaches following recent heavy rainfall.
The advisories affect beaches across the coast and come amid concerns that stormwater runoff may have contaminated the water with potentially harmful bacteria.
Multiple Beaches Under Water Advisory
The Mississippi Department of Environmental Quality (MDEQ) has issued water contact advisories for five coastal beaches, including:
- Bay St. Louis Beach
- Long Beach Beach
- Gulfport West Beach
- Gulfport Harbor Beach
- Biloxi East Central Beach
Officials say the advisories were issued after testing detected elevated levels of enterococci bacteria, which can pose health risks to swimmers and anyone coming into direct contact with contaminated water.
While the beaches remain open to the public, authorities are warning visitors to avoid swimming until conditions improve.
What Is Enterococci?
According to the U.S. Environmental Protection Agency, enterococci are bacteria commonly found in the intestinal tracts of warm-blooded animals, including humans.
The bacteria are often associated with fecal contamination and can enter waterways through several sources, especially after periods of heavy rain.
“Enterococci are bacteria that live in the intestinal tracts of warm-blooded animals, including humans, and are commonly found in fecal matter.”
Health experts warn that exposure to contaminated water can potentially lead to illnesses, particularly stomach-related infections, skin irritation, and other health concerns.
Heavy Rainfall Believed to Be Major Factor
Officials believe the recent storms and significant rainfall played a major role in the spike in bacteria levels along the Mississippi coast.
When large amounts of rain fall in a short period, stormwater runoff can carry waste, pollutants, and bacteria into nearby rivers, bays, and ocean waters.
“When enterococci is found in lakes, rivers or ocean water, it can be caused by a number of factors, including stormwater runoff.”
The advisory for Bay St. Louis Beach was the most recent and was issued Thursday. Some of the other advisories have remained active for several weeks or even months due to continued unsafe test results.
Beaches Remain Open Despite Health Risks
Although the beaches have not officially closed, the MDEQ is strongly discouraging swimming and unnecessary water contact while the advisories remain in place.
Officials emphasized that people entering the water during this period may risk becoming sick due to bacterial exposure.
In recent weeks, several other Mississippi beaches were temporarily placed under advisories as well. Those warnings were later lifted after testing confirmed that bacteria levels had returned to safe ranges.
The latest water samples collected Thursday showed that the affected beaches still exceeded recommended safety levels, keeping the advisories active.
Officials Monitoring Conditions Closely
State environmental officials say they will continue monitoring water quality and conducting additional testing at impacted beaches.
Once bacteria levels return to acceptable standards, the advisories will be removed and beaches will again be considered safe for swimming and recreational water activities.
For now, residents and tourists are being encouraged to stay informed before heading to the coast, especially following periods of heavy rainfall.
