Floodwater can be contaminated by sewage systems, agricultural and industrial waste and septic tanks — all a major hazard for children allowed to play in it.

Toys that have been in floodwater must be cleaned with a quarter-cup of bleach to a gallon of water before allowing children to play with them, the Mississippi State Department of Health advises.

Cuts or sores exposed to floodwater must be cleaned with soap and water, and treated with antibiotic ointment to reduce the risk of infection, the agency said.

MSDH also advises receiving a tetanus shot if it’s been more than 10 years since the most recent vaccination.
