Officials from Oklahoma City-County Health Department warn Oklahoma residents to be careful of outdoor hazards and food-borne illness in the aftermath of tornado damage and power outages.
About half of all tornado-related injuries happen during rescue and cleanup work, according to the Centers for Disease Control and Prevention. Major concerns include falling objects, downed power lines and gas leaks.
As many as 1 in 3 injuries can be from stepping on nails, raising concern for a tetanus infection.
Health department nurses will offer free tetanus shots today to rescue workers, residents and volunteers.
The shots will be available at the Blue Cross Blue Shield Caring Vans at 7501 S Anderson Road near Interstate 240.
Food stored in refrigerators and freezers can spoil during power outages, according to the health department. Food is unsafe to eat if it is stored above 40 degrees for more than two hours. Foods of particular concern are meat, poultry, seafood, milk and mayonnaise.
Bacteria in affected foods cannot be killed even with thorough cooking.
Generally, food won't spoil in an unopened refrigerator for four hours or less, according to the health department. Frozen food will be OK for up to 48 hours in a full unopened freezer or 24 hours in a partially-full freezer.
