I reported this last week - it is nasty and there is definitely something that was once flesh in that bag. Bring your hazmat suit.

City of Oakland Public Works Agency referred this issue to OPD ANIMAL SERVICES, service request # 481070. Please contact that agency to follow-up. For more information, please visit the "Helpful Links to Other Resource Partners" at the link below.

Thank you.

The bag is gone.
