PRO/AH> Die-off, farmed fish - Nepal: (BR) RFI - ProMED Mail - 09/13/2016


Nearly 50 000 fish have perished in the past month in different parts of Bardia due to a mystery disease. Most of the deaths have been reported from Sorahawa and Basgadi, which are known as fish pocket areas. Fish farmers said that around 1000 fish farmed in ponds and lakes were dying daily.

Fish ponds are filling up with dead fish and farmers have not been able to identify the disease that may cause their ruin. More than 20 000 fish raised on 75 hectares [about 185 acres] in Bardia Lake have died. One local fish farmer said he was losing 200 to 300 fish daily.

The District Agriculture Office has started to spray medicines on the ponds and lakes to control the disease. There are no labs in the Mid-Western Region to identify the di

An outbreak of dangerous _Escherichia coli_ foodborne illness that
closed the Matador restaurant in Seattle's Ballard neighborhood last
week [week of 5 Sep 2016] appears to be linked to more illnesses in
Washington and 3 other states, health officials said [on Mon 12 Sep
2016]. 5 people were sickened with a Shiga toxin-producing strain of
_E. coli_ O157:H7 after eating at the restaurant in August 2016. 3
people were hospitalized, including a 16 year old girl who developed a
dangerous kidney injury called hemolytic uremic syndrome.

But 2 more Washington cases -- one in Skagit County, one in Snohomish
County -- have been detected that have no known connection with the
Matador, a spokeswoman with the state Department of Health said on Mon
12 Sep 2016 and 3 cases with the same genetic fingerprint have been
detected in 3 other states, officials with the Centers for Disease
Control and Prevention [CDC] indicated. 1 of those people visited
Seattle and ate at the Matador in Ballard.

That's a total of 10 cases of what are known as EHEC infections -- but
just 6 of those cases now appear related to the restaurant. The
investigation is fluid and ongoing, local health officials emphasized.
It may turn out that the additional cases aren't part of the same

Still, reports of such dispersed illnesses with a similar genetic
fingerprint indicate that the problem might not lie entirely with the
Matador in Ballard. The restaurant closed on Friday [9 Sep 2016] after
inspectors with Public Health - Seattle & King County said they
temporarily suspended the firm's food business permit to allow
thorough cleaning and sanitizing.

"It's looking more like a potential source, a contaminated product,"
said Dr Meagan Kay, a medical epidemiologist with King County. State
and federal officials have taken over the probe, she added.

The recent Matador illnesses include 4 people who ate at the
restaurant on 14 Aug 2016 and one who did so on 22 Aug 2016. Another
person ate there sometime between those dates. Public health officials
received the 1st report of illness on 22 Aug 2016; the most recent
case was reported on 6 Sep 2016. The 5 people developed symptoms of
ETEC O157:H7 poisoning, including diarrhea and abdominal cramps. 4
people developed bloody diarrhea. 3 were hospitalized, including the
teenage girl, who ate leftovers from the Matador. All have recovered.

[This outbreak originally associated with a single restaurant in
Washington state [see: ProMED-mail. E. coli EHEC - USA (31): (WA)
restaurant http://promedmail.org/post/20160911.4480793] has now spread
to other counties and other states. That the infection was transmitted
over a period of at least 23 days suggests that a product with a
longer self life than fresh produce may be involved or the produce was
contaminated serially. - Mod.LL
