Cucurbitacin is a poison that plants make to protect themselves against insects. Even a few bites of bitter squash could have consequences. High quantities of the toxin can be caused by cross-pollination with wild plants, as well as some form of stress during growth.

Should you bite into squash or baby marrow and get a bad taste, spit it out, and don’t eat anymore. Likewise, avoid eating any “volunteer” zucchini or acorn squash you didn’t plant as a crop in your garden.

If there are ornamental pumpkins and gourds planted alongside squash, don’t consume these as they can also contain cucurbitacin.

If the toxin levels are too high, it might induce:

  • Abdominal Pain and Diarrhea
  • Nausea and Vomiting
  • Dizziness

In your garden, zucchini goes bad when not harvested as the fruit is immature. If left on the plant too long, zucchini becomes tough and loses flavor.

Sometimes, zucchini can rot on the plant before harvest, thus showing the plant hasn’t been pollinated or suffers from blossom-end rot. Blossom end rot can be from too much nitrogen, uneven watering, or over-fertilization. The fruits basically grow too fast for the amount of water they have.

Zucchini is ready to be harvested when it’s 6 to 8 inches long. It should feel firm with shiny or glossy skin. If the skin appears dull, it is the first sign your zucchini sold, use-by date, or shelf-life is already up.

Once you cut a healthy zucchini, it has an almost buttery texture with flesh that looks faint yellow, green, or possibly white. Zucchini flavor is mild and juicy, and the meaty flesh means cooked zucchini stands up to grilling, sauteing, and baking zucchini bread.

Should just a part of the vegetable be damaged or is soft or wrinkly, and the inner flesh mushy, it is a matter of cutting away this part and so long as the main part of the zucchini still has color, texture, and smells fresh, it should still be good enough to use.

If the zucchini isn’t spoiled, open the bag. Remove one of your squash so you can examine it up close.

Check for any signs of damage, like large soft or bruised spots, or even if you used a vegetable brush before you put the zucchini in the fridge. If you see bad parts, cut these away using a sharp knife. If you have a firm squash and the bruise is just in the skin, the rest of the sliced zucchini squash can be used.

If the zucchini part that is spoiled reaches deep inside the zucchini flesh, cut the zucchini lengthwise to check the interior for streaks or soft, watery-looking areas.

If there is no visible damage or rot, gently squeeze the zucchini. If still okay to use yet it’s losing freshness, it will feel slightly rubbery.
