Fishy Fruit

[maskedmelon]

I have noticed that some fruits smell fishy. At first I thought it was bad or contaminated and so through it away. I was much more cautious from that point forward and made sure to give any new fruit a good sniff before committing to it. it surprised me to find hat pretty much all bananas and grapes have this fishy smell. It don't matter which store I buy it from or what one of year or anything. It all smells like fish if you sniff it. Washing it doesn't seem to do much good and if it does, the smell just returns unless you eat it all immediately.

Anyone else notice this? What's going on here?
