Chayote (Chow Chow) Quality Check
Chayote (Chow Chow) is a hard vegetable but can suffer from internal spoilage or high pesticide residues on its deep-ridged skin.
1. The Squeeze Test:
Firmly press the chayote. It should be rock hard. Any soft spots, especially near the base, indicate internal decay and fungal growth.
2. The Skin Ridge Inspection:
Examine the ridges carefully. High pesticide residue can often be found trapped in the tight creases. Check for any white or bluish powdery residue.
3. The Internal Core Check:
Cut the chayote. The flesh should be crisp, white to pale green, and the single large seed should be moist. If the center is brown, black, or mushy, discard it.
4. The Appearance Scan:
Fresh chayote has a bright, light green color. Avoid ones that look shriveled, have deep dark brown pits, or have turned yellowish.
Quick Safety Tips

Frequently Asked Questions
How do I remove pesticides from Chayote ridges?
Soak the chayote in a solution of water and baking soda or vinegar for 20 minutes, then use a soft brush to scrub the deep ridges thoroughly.
Why is my Chayote soft at the base?
Softness at the base or stem end is a sign of post-harvest fungal infection or internal rot. If it yields to gentle pressure, it is likely spoiled inside.
Can I eat Chayote with brown spots inside?
Small brown specks near the seed may be natural, but large brown or black patches in the flesh indicate age or disease. It is safer to discard such fruits as they may contain mycotoxins.
Does Chayote need to be peeled?
While the skin is edible, most pesticide residues stay on the surface. For maximum safety, peeling is recommended, especially if you cannot scrub the ridges clean.
