MARYSVILLE, CA - The death of more than 20 ducks and geese at Lake Ellis was determined to be caused by Botulism, according to California Fish and Game.
The birds were found dead along the shoreline of the lake in the end of April.

A drake Mallard that was found dead by Marysville police was taken to UC Davis for a necropsy, Capt. Mike Wilson said. Scientists found the duck died of avian botulism.
Wilson said the birds were most likely exposed to the botulism by people feeding them.
"While people enjoy the opportunity to feed the ducks; bread, chips, pretzels, etc. the effects can be very hazardous for the wildlife," Wilson said.
The public is not at risk of being infected by the bacteria. However, with their help to avoid feeding the wildlife in the area, the public can help decrease the risk of more animals dying.
