There is no risk of lead leaching from old aluminum cans into food during recycling. Aluminum cans are made of aluminum and do not contain lead. The recycling process involves melting and re-forming the aluminum, which effectively removes any potential contaminants. Lead was used in some can linings in the past, but modern food cans are lined with non-toxic materials. Therefore, recycled aluminum cans pose no lead leaching risk to food safety.
