Swimmers, boaters urged to avoid toxic blue-green algae

STOCKTON — San Joaquin County’s Public Health and Environmental Health departments are urging people to stay away

from toxic blue-green algae in local waterways this summer.

As temperatures heat up, conditions are ideal for toxic algae blooms on the surface of rivers, lakes, creeks, lagoons, ponds, reservoirs and other local waterways.

The blue-green algae, also known as cyanobacteria, may produce toxins that can endanger anyone — and any pets — exposed to it.

With mild exposure, humans may experience rashes or other skin irritations, allergic reactions including a runny nose or sore throat. If exposed in larger amounts, patients may experience sharp and severe stomach problems, including diarrhea and vomiting; liver damage; numb limbs or tingling fingers and toes; or dizziness. Children are especially

vulnerable.

Animal exposure, especially among dogs, can cause weakness, staggering, difficulty breathing, convulsions, vomiting, diarrhea and, without immediate treatment, death.

If you, your child, your pet or livestock might have been exposed, get immediate medical treatment.

Additional safety tips: Don’t drink, cook or wash dishes with untreated surface water. Be sure to clean fish thoroughly, remove the guts and liver, and rinse fillets before eating. Do not eat mussels from local waterways.
