After so much smoke, can harvest still be eaten?

We’ve had smoky skies and falling ash for 25 consecutive days. These apocalyptic-like conditions make it difficult for anything to grow.

Still, our gardens persist. Green tomatoes continue to mature on the vines. Zucchini keeps growing rapidly. Apples, pears and persimmons are ripening on the trees.

But that leads to another question: Will what we grow be safe to eat?

Yes, but our harvest will need a little extra TLC before consumption.

The wildfire ash we’ve been experiencing should not harm most fruit and vegetables. It may give tomatoes and grapes a smoky or ashy flavor because their thin skins absorb smoke compounds.

Before eating, wash everything thoroughly, even crops such as melons or hard squash with rinds that won’t be consumed.

As for washing, follow these USDA recommendations:

A sprayer is useful in cleaning kale leaves after they've been dunked for a few minutes in a bowl of water.

Leafy greens: The grit of ash can get down into the wrinkles of leaves (especially kale and spinach). Fill a large bowl or the sink with water. Submerge the leaves totally in the water and swish them around gently. Let sit for a couple of minutes, so grit can fall to the bottom of the bowl or sink. Remove leaves and place in a colander, discarding the water in the sink or bowl. Then, run the leaves under cold water, turning each leaf over individually. A sprayer works wonders for this task.

Sturdy fruit and vegetables: This includes beans, squash, apples and citrus. Wash thoroughly under a hard stream of cold water. Use a vegetable brush to softly scrub off grit. Let dry in a colander.

Delicate fruit and vegetables: This includes tomatoes as well as berries and ripe stone fruit such as peaches and pluots. Wash thoroughly under a steady but low-pressure stream of cold water, turning the fruit repeatedly as you rinse. Treat it gently to avoid bruising. Spread out on paper towels or clean cloth towels to dry.

When in doubt, peel. That goes for tomatoes as well as other fruit and vegetables.
