Officials warn fiddleheads may be unsafe following massive flooding

People in New Brunswick are being warned not to pick or buy produce in areas affected by flooding.

The Emergency Measures Organization says produce, including fiddleheads, exposed to flood water may not be safe to eat.

It says floodwaters may have untreated sewage, fuel or other industrial contaminants and that fiddleheads grown in affected areas could have been exposed.

Boiling would only be effective against microbial contamination, not chemical exposure.
