I'm wondering if this spotted fruit is diseased or safe to eat or cold-compost, and if it's ok to just cut off the spotted part and eat the rest.

I'm wondering if the fruit spots are related to the yellow and brown foliage which has affected much of this plant (on high as well as low parts). This plant (also shown in photo below) was started from a sucker from one of my potted plants. The potted one had uniform red colored fruit, unlike this one, and did not have foliage disease at the time the sucker was pruned. Due to my carelessness, some of the stems of this diseased plant cracked and bent over from the weight of the tomatoes, and leaves were touching the soil. No tomatoes were planted in this spot for at least 30 years. However, the yard is very windy.

This hybrid from our university is resistant to the common root knot nematode, fusarium wilt, gray leaf spot, one strain of spotted wilt virus, and tobacco mosaic virus.
