Vibrio Returns to Puget Sound: Hood Canal Growing Area 6 Impacted

Vibriosis traced to oysters

from Hood Canal

The Department of Health has notified shellfish growers of vibriosis contracted from oysters traced to Hood Canal Growing Area #6. They are now requiring shellfish growers in Area #6 to reduce the "time to temperature" to one hour. DOH is required to act if 2 or more cases of vibriosis are reported which can be traced to a specific growing area.

Combination of Minus Tides

and Higher Temperatures



As noted earlier in the month, the combination of higher than normal temperatures and minus day time tides increases the risk of vibrio in oysters causing illness. April 30th, DOH issued a warning to shellfish growers to be aware of the increased risk to consumers. Warmer than normal temperatures for this weekend, combined with minus day time tides, may again increase the risk of contracting vibriosis from oysters harvested from Puget Sound.
