Leafy Greens (Spinach) Safety Inspection
Detect copper sulfate spray and pesticide residues in leafy greens
Inspection Guide

Leafy Greens Safety Check
Spinach and other leafy greens are often sprayed with copper sulfate to keep them looking fresh and dark green for extended periods.
**1. The Color Test:**
Natural spinach is a medium to dark green color. If the leaves are excessively dark green, almost bluish-green, or have an unnatural vibrant hue, copper sulfate treatment is likely.
**2. The Wilting Test:**
Buy the greens and observe them at room temperature. Natural leafy greens should start wilting within 3-4 hours. If they remain fresh and crisp even after 24+ hours without refrigeration, they've been chemically treated.
**3. The Taste Test:**
Wash a leaf and taste a tiny piece raw. Natural spinach has a mild, earthy taste. If you detect a metallic, bitter, or chemical taste, it indicates copper sulfate or excessive pesticides.
**4. The Insect Check:**
Look for small holes or minor insect damage on some leaves. While this might seem undesirable, it actually indicates minimal pesticide use and is a positive sign. Perfectly pristine leaves with zero damage are suspicious.
**Safety Tip:**
Always soak leafy greens in salted water (1 tablespoon salt per liter) for 20 minutes. Then rinse thoroughly under running water at least 3 times. This helps remove copper sulfate and pesticide residues.
