Wiygul began her description of her family's rigorous test by noticing that her father had compromised the immune system due to cancer.
"He has been fighting cancer for years and has been in the water several times so it does not seem to be a risk," she wrote.
However due to the recent reports of infections among people visiting Florida's shores, Wiygul said he researched the subject and took precautions if his parents visited from Memphis in early July. His father had "no open wound," and he guarantees that some tiny scratches in his arms "are so sealed," he wrote.
During their visit, he and his parents spent time on a boat on the shore, boarding a ship and dumping a bayou, waving a creek, sinking into a pool and went to Destin beach .
"Daddy sits late at night and watches a movie," Wiygul writes, adding that "he's been doing something fine all week."
However, at 4:00 am Saturday ̵1; just 12 hours after their last swim – he woke up with fever, trembling and waving.
Wygul writes: "The legs began to get very painful, he became extremely uncomfortable. "
The hospital began with him in IV antibiotics , her daughter said.
More black spots appeared on her skin, and "she was in a great deal of pain," he wrote. "At 1 am he became septic and transferred to ICU … They said his organs were damaged and his blood was too acidic to preserve life. He disappeared on Sunday afternoon."
Wednesday's lab results confirmed Wiygul's suspicion: "Vibrio vulnificus showing necrotizing fasciitis (meat food bacteria) eventually leads to sepsis," she said.
The hospital confirmed that Wiygul's father was being treated there but did not provide further details about his condition; Wiygul did not respond to CNN's request for further comment.
Second recent death
Wiygul's father was the second man who had died last week after contracting bacteria eating water in Florida.
How Vibrio can be fatal
Most Vibrio infections occur between May and October, when temperatures are hot. The food-eating bacteria stops blood circulation and causes tissue death and decay, according to the CDC.
More than one type of bacteria can eat flesh this way; Public health experts believe that the A Streptococcus bacteria group is the most common cause of these infections. Vibrio infections occur when a person eats raw or inadequate seafood or when the open wound is exposed to saline or salty water.
Blunt trauma that does not break into the skin may also allow the insertion of the flesh eating bacteria, according to the CDC. Many antibiotics may deal with these injuries, even if the cases are severe, may require skin and surgery.
Good care of the wound is the best way to prevent any bacterial skin infection, according to the CDC. It is important to clean even the minor and injuries that blow the skin with soap and water. Always clean and cover the draining or open wound with dry bandages until they are healed. And check out a doctor for puncture and other deep or serious lesions.
Wiygul said that people "need to know how to be more careful and how to identify symptoms," and he expects them to pass on information to "help others."
"I am really not trying to scare people from the beach or swimming," he wrote. "I love water and my dad."
