San Francisco Bay keeper, a Bay Area pollution watchdog, said the runoff produced from holiday foods cause winter season sewage spills.
Foods with a high amount of fat, oil and grease deposit much of it down the drain during the cleanup of dishes, p-ans and fryers. These substances then solidify into sewage clogs that can cause sewage to backup into neighborhoods, Baykeeper said.
Backups can cause untreated sewage to fl ow into storm drains and local creeks out into San Francisco Bay, they added.
