Tests were done throughout the beaches of the Jersey Shore and quite a few showed higher levels of the bacteria found in animal or human waste.

Swimming advisories have only been established for those that are open for the season and most with higher readings are along bays rather than oceans.

"It takes a few tide cycles for it to mix, and it dissipates more quickly at ocean beaches," said DEP Spokesman Larry Hajna.

Take a look at the areas to avoid for now:

Monmouth County:

Community Beach Center - Highlands (Not open for season yet)

Thompson Avenue - Middletown (Not open for season yet)

Pavilion Beach - Monmouth Beach (Open for season)

Ocean County:

Anglesea Avenue - Ocean Gate (Not open for season yet)

Wildwood Avenue - Ocean Gate (Not open for season yet)

Side affects of swimming in contaminated water can result in symptoms such as nausea, vomiting, diarrhea, abdominal pain, sore throat, runny nose, sneezing, skin irritation and itchiness.

But don't let the list of side affects send you into a crazed panic because Hajna adds, "Everything is geared toward erring on the side of caution."

Beaches are going to be retested today but the results will not be released until at least later on this afternoon.
