NEW PARTNERS, NEW RESOURCES
ECHO: Bridging the Gap for Immigrants and
Refugees in Minnesota
Joanna Olson, ECHO
Part One: What is ECHO?
The cultural landscape in Minnesota is constantly
changing. Each year, 18,000 immigrants settle in
Minnesota. Nearly half a million residents speak a
language other than English. That means English
isn’t spoken in ten percent of Minnesota homes!
To ensure that these individuals receive vital health,
safety, emergency and civic engagement information,
ECHO was formed in 2004 to help this diverse
population integrate and become successful in
Minnesota’s communities.
ECHO communicates this crucial information in seven
languages (Somali, Hmong, Spanish, Lao, Khmer,
Vietnamese, and low-literacy English) via a television
show broadcast on tptMN, a website that houses all
past shows and topical information, public service
announcements, and outreach activities within the
community.
Part Two: Minnesota Department of Agriculture
Calls on ECHO to Spread Food Borne Illness
Warning
ECHO’s (Emergency, Community, and Health
Outreach) system for quickly communicating critical
health information was recently activated in April when
the Minnesota Commissioner of Agriculture’s office
placed a call to ECHO.
MDA officials had discovered and embargoed more
than 400 pounds of dried uneviscerated fish at ethnic
grocery stores in the Twin Cities due to the high risk of
it being contaminated with Clostridium bacteria known
to produce potentially deadly botulinum toxin.
However, they did not have a means to get this health
information out to the East African individuals and
families that had already purchased the product.
Within a few short hours, ECHO had translated the
Department of Agriculture’s news release into Somali
and Oromo. It was then circulated through ECHO’s
partner system to key contacts within the East African
community, ethnic media, and was posted on East
African websites. The word about this potential foodborne illness was successfully spread within the East
African community.

FOOD and FOOD SAFETY MATTERS
Minnesota Salmonella Cases Linked to
Nationwide Recall of Frozen Meals
Minnesota Department of Health (MDH) News
Release, June 18, 2010.
Summertime Consumer Resources:
Old and new materials for those of us who receive food
safety inquiries from the public:

Two recent cases of salmonellosis in Minnesota were
linked to a national recall of Marie Callender’s brand
Cheesy Chicken and Rice frozen meals.
The Centers for Disease Control and Prevention (CDC)
are conducting an investigation involving 30 people in
15 states who have been diagnosed with infection of a
rare type of Salmonella called Salmonella Chester.
Eight of the cases reported eating this product in April
and May 2010 prior to becoming ill.
MDH determined that there have been two cases of
infection with Salmonella Chester in Minnesota, and
that both cases ate the Marie Callender’s product that
was recalled. The Minnesota Department of Agriculture
isolated Salmonella Chester from an intact package of
Marie Callender’s Cheesy Chicken and Rice collected
from the home of one of the ill people.

2010 LEGISLATIVE ACTIVITIES
There were a couple of unexpected bills

Legislative Activity Related to Food
Colleen Paulus, MDH
MDH had two legislative initiatives:


Consolidation of lodging terms: House File 3476,
author, Representative Laine. After several
hours of testimony the bill was tabled. Review
this bill at:
http://www.house.leg.state.mn.us/bills/billnu
m.asp?Billnumber=HF3476&ls_year=86&sess
ion_year=2009&session_number=0
MDH submitted language to make slight
corrections to statute language. During the 2009
legislative session, changes were made to
statute that resulted in unintended
consequences. One resulted in some youth
camps paying two license fees and the other
was that Manufactured Home Parks paid two
base fees. Both situations were corrected during
the 2010 legislative session. The following two
items are found in larger bills. A summary of the
language is provided:
Youth Camps: The following correction was
made to Minnesota Statutes Section 157.16
Subd. 3 (i):
This bill modified Minnesota Statute Chapter 157
and added language that says concessions
stands operated by the schools do not have to
pay an additional license fee.

ENVIRONMENTAL ODDS and ENDS
Asian Carp: Coming Soon to a River Near You
Asian carp (seen at left in a
photo from the U.S. Fish
and Wildlife Service) were
imported by catfish farmers
in the 1970s to remove
algae and other matter
from ponds. When ponds
overflowed during floods in
the 1990s, the carp made it
to the Mississippi River and
have been steadily
swimming north.
Manufactured Home Parks and Recreational
Camping Areas: The following correction was
made to Minnesota Statutes Section 327.16:
License Required; Renewal; Fees
Subd. 3. Fees, manufactured home parks and
recreational camping areas
(iii) 100 or more sites, $300.

BUG of THE QUARTER
(Recognizing and Regulating) Non-O157 shiga
toxin-producing E. coli (non-O157 STEC)
"Whatever the serotype, if a bacterium is making Shiga
toxins in the gastrointestinal tract of an infected
individual, that person is at risk for developing
[hemorrhagic colitis] and HUS."
(David Acheson and Gerald Keusch ASM News)
Background
For most Americans, E. coli is the name of a bug that
is associated with serious illness, occasional death,
and a growing awareness of food safety concerns.
E. coli became part of the national vocabulary in 1993,
when hundreds of people became ill and four children
died after eating adulterated hamburger patties at Jack
in the Box restaurants. Some people – including those
who have suffered from ill effects of E. coli-caused
foodborne illness – may know the full name of that
culprit, E. coli O157:H7 or the shorter version, O157.
However, many fewer people know that there are more
than 250 types of E. coli that produce Shiga toxin - the
toxin that can cause illness with severe stomach
cramps, and bloody diarrhea, and that may trigger the
life-threatening hemolytic uremic syndrome (HUS).
Of the many types of E. coli, there are six lesscommon strains have been identified as causing most
of the non-O157 shiga toxin-producing E. coli (or
non-O157 STEC) cases in the U.S. The CDC
estimates that these six strains (O26, O45, O103,
O111, O121 and O145) cause 36,700 illnesses, 1,100
hospitalizations and 30 deaths in the U.S. each year,
compared to about 73,000 illnesses for O157.
For example, in 2008, E. coli O111 infected more than
300 patrons of an Oklahoma restaurant. Seventy
people were hospitalized, 17 with HUS required
dialysis, and one died. Most recently, at least 26
people in five states - including three teenagers who
suffered kidney failure - became ill this April after
eating bagged romaine lettuce contaminated with
E. coli O145.
Evidence for Testing in Human Cases
The evidence that non-O157 STECs are present in the
food supply and causing significant illness is well
known by food scientists, the government and industry
but little has been done to regulate these toxic strains.
PWDU Quarterly Newsletter
In an August 2007 letter to the journal, Emerging
Infectious Disease, a group of Idaho scientists made
the case for routine culture for non-O157 STEC:
"Several studies have shown an increased incidence
of non-O157 STEC infections in the United States.
For example, a community hospital in Virginia
detected non-O157 serotypes in 31% of patients with
STEC from 1995–2002 (1). A 1998 Nebraska study
that analyzed 30,000 diarrheal stool samples found
that non-O157 and O157:H7 STEC were equally
prevalent (2). Additionally, findings from a
Connecticut study of laboratory-confirmed cases (3),
STEC surveillance results from Montana (4), and a
recent study from Michigan (5) indicate that nonO157 serotypes comprise a substantial percentage
of STEC cases.”
These and other researchers say that routine testing of
patients for the “big six” non-STECs is not performed
for two main reasons, cost and the (perhaps, now
diminishing) perception that the incidence of non-O157
STEC infections is very low.
Minnesota Data:
In a Minnesota study looking at non-O157 cases
from 2000 to 2006 (See Hedican et al reference
below), the number and proportion of STEC cases
indentified each year in Minnesota increased from
2004 to 2006.
Of 206 STEC-only cases, 108 (52 percent) involved
non-O157 serotypes and 98 (48 percent) involved
O157.
Five serotypes represented 74 percent of the nonO157 isolates: O26, O45, O102, O111, and O145.
Four of the “big six” are included in this group.
Legislation, Petition
Pressure for change is coming from other quarters as
well. Senator Kirsten Gillibrand (D-N.Y.) recently
proposed legislation to require USDA to regulate the
“big-six” non-O157 STECs. The law would make it
illegal to sell ground beef contaminated with the six
non-O157 STECs by including them in the definition of
adulterated meat. It would require meat companies to
test for and discard batches of ground beef containing
any of the described toxic strains, and would allow
USDA to identify and regulate additional strains in the
future.
Page 6 of 9
Non-O157 STEC, continued …
At the same time, Marler Clark LLP has filed a citizen
petition with the USDA-Food Safety and Inspection
Service, “Petition for an Interpretive Rule Declaring all
Enterohemorrhagic Shiga Toxin-producing Serotypes
of Escherichia coli including Non-0157 Serotypes, to
be Adulterants Within the Meaning of 21 U.S.C. §
601(m)(1).”
The consumer advocacy group Safe Tables Our
Priority (STOP) has also petitioned UDSA, requesting
that they expand the definition of adulterant to include
E. coli O157:H7 and the six other STECs when they
are in any type of beef, not just ground beef or beef
intended for ground beef.
The petitions from Marler Clark and STOP essentially
request that USDA take action on the matter of nonO157 STECs. The legislation would circumvent what
has already been a lengthy government process by
creating new law requiring immediate action.
Response from Industry and Others
"We share Sen. Gillibrand’s desire to eradicate
pathogenic bacteria, but we don’t believe that an act
of Congress can make these bacteria disappear.”
(American Meat Institute Statement)
In addition to saying that declaring non-O157 STECs
an adulterant would do little to enhance food safety, a
statement from the American Meat Institute claimed
that there is no test available to detect the six toxic
strains. The reality may be that there is no cheap and
simple, rapid test available to the industry.
The meat industry is not alone in their opposition to a
law imposing immediate regulation of non-O157
STECs.
Dr. David Goldman, assistant administrator for the
Office of Public Health Science for FSIS, says the
agency is reluctant to broaden the definition of
adulterant until a reliable and rapid test is ready for the
market. He said that such a screening tool would be
available in the “next six months or so.”
However, the agency currently plans to do its own
testing to determine the extent to which the non-O157
strains exist in the meat supply before taking any
action.

PWDU Quarterly Newsletter
One (massive) retailer doesn’t plan to wait for either
legislation or government action. In late April, Walmart
announced that it would require specialized testing for
E. coli O157, Salmonella, and non-O157 strains of E.
coli in meat products purchased for Walmart and
Sam’s Club stores.
"In light of recent beef recalls, we determined it was
prudent to require an additional layer of protection for
our customers," said Frank Yiannas, Walmart's vice
president for food safety. "As part of our continuous
improvement efforts, we go further than many U.S.
retailers in requiring leading-edge food safety
standards throughout the entire food production chain."

Second Annual FSP Farm to Fork Field Trip: Appert’s Food Service, St. Cloud and Donnay Dairy, Kimball.
We didn’t get many photos at Appert’s
because cameras weren’t allowed, but
Lynne Markus and Angie Wheeler got
these shots of the front entrance, and of
Field Day participants getting all dolled
up for their visit to the production plant .
Everyone liked most of the tour but hardly
anyone wanted to stay long in the
gigantic freezers.
Both tour groups asked a lot of questions about cheese processing at the Donnay Dairy. (Yes, the
cheese is pasteurized, and yes, the family drinks raw goat’s milk) However, the goats seemed to be the
biggest attraction. Brad Donnay milks 132 goats twice a day. And no, goats won’t eat just anything.
Although they nibbled at a few shirts and fingers, everyone and most every thing departed intact.
