A 38-year-old man sought help from urologists after suffering redness, swelling and scabbing on his penis, which had persisted for the best part of a week.
Further investigations revealed that the troubling symptoms had begun soon after he’d suffered a bout of severe diarrhea and vomiting.
The doctors, at the American University of Beirut Medical Center in Lebanon, where he was treated, took a swab of the man’s penis to test for infection.
They found evidence of the bacteria bacillus cereus, which is usually found in rice that’s been left out at room temperature for too long and can cause sickness and stomach upsets if eaten.
The doctors concluded that the man’s unusual genital infection had been caused by an episode of diarrhea and vomiting that occured almost immediately after ‘vigorous sex’ with his wife.
The intimate act can increase the risk of bacteria permeating the skin due to the change in blood vessels.
The bacteria was said to have made direct contact with the patient’s groin.
The doctors remarked that it was ‘unusual’ to see bacillus cereus in the skin, let alone the genitals.
This was the ‘first case in literature’ of the food poisoning in the penis.

Yeah, it’s pretty toxic which is why your body has such a rapid (possibly 30 minutes) and violent reaction.
It’s called “fried rice poisoning” because people often leave some leftover rice to stir fry the next day. It’s fine if you know what you are doing, dangerous if you don’t. Basically cool your rice down immediately by running cold water through it and then reheat it when needed, keeping everything in the fridge if you are using it the next day. However, you are best off cooking what you need for that day.
