Yes, don't eat tomatoes for a while and also don't eat black olives , mushrooms or any kind of seeds.
The first picture does indeed resemble a buski fluke but the second does look like tomato.
Don't eat anything red either.
They are black, pink, red,tan,and orange/red in color.
Also there might be the hard ones that are raised and asymetrical in shape. Sometimes flat on one side and raised on the other.
All these vary in size and color..these are flukes.
