How would you know if you could be putting your family at risk?
The DEA has released a list of clandestine meth labs on record.
Authorities said you should only use the information as a starting point because the list may not include every police action.
The list also does not say whether anyone cleaned up the site.
In some cases the home was torn down and replaced with a new one.
In other cases, homeowners may have paid for complete meth remediation.
