Copper is a Mitigation Solution
Currently, stainless steel or plastics are used
for sinks, counters, beds and other surfaces in
health care environments, but while stainless
steel and plastic are easy to clean (the main
reason they're used in such places), they also
demonstrably harbor far more bacteria and
viruses than a similar copper surface does — and
over time, small scratches, dings and holes can
hide even more.
It's especially important that the most
dangerous superbugs, responsible for the death
and illness of already-sick people, are killed
by copper. That includes methicillin-resistant
staph (MRSA); other staph bacteria;
adenoviruses; the flu virus (all types); and
even fungus. In
a study published in the International Journal
of Food Microbiology,
99.9 percent of E.coli bacteria was killed after
an hour on a copper table, whereas it survived
for weeks on stainless steel.
Considering that last fact, it seems that copper
tables and prep areas in restaurants and
food-prep areas would be another place copper
could make a dent in keeping the nastiest bugs
away from vulnerable people.
Copper kills the variety of bacteria and viruses
that it does because it works on several levels
to disable the organisms. It binds to proteins
that disrupt the basic function of the cell, it
breaks down membranes that cause cell drying and
then death, and it causes oxidative stress to
any cells it comes into contact with, also
destroying them.
We're used to seeing copper as a trendy metal in
kitchens and bathrooms or used in pots and pans
in kitchens — and using it in these places is
beneficial. In fact, it would make sense to use
copper, especially, in places that see a lot of
hands and don't get washed often, like drawer
pulls in the kitchen, or bathroom taps.
But the material could be used to save lives in
far more fraught and dangerous settings, like
hospitals, elder-care facilities, and places
where the sickest and most vulnerable of us
spend time. That's why there are already several
hundred patents for health care surfaces and
tools made from copper, though a materials
transition will take time, especially where
health care budgets are stretched thin or
otherwise constrained
Queensland University Develops Highly Efficient
Nanocellulose Mask Media
The new mask media is biodegradable, efficient
in capturing virus and has low resistance.
Process engineer Thomas Rainey and his research
team are stepping up work on a
nanoparticle-removing new material they were
developing for biodegradable anti-pollution
masks.
“We have developed and tested a highly
breathable nanocellulose material that can
remove particles smaller than 100 nanometres,
the size of viruses,” Rainey said. “I see many
people wearing masks which are not tested for
viruses. We have tested this material thoroughly
and found it to be more efficient in its ability
to remove virus-size nanoparticles than the
high-quality commercially available masks we
tested and compared it with.”
Rainey said the team also tested the new
material for breathability.
“By breathability we mean the pressure or effort
the wearer has to use to breathe through the
mask. The higher the breathability the greater
the comfort and reduction in fatigue,” he said.
“This is an important factor for people who have
to wear masks for long periods or those with
existing respiratory conditions. Our tests
showed the new material was more breathable than
commercial face masks, including surgical
masks."
This new material has excellent breathability,
and greater ability to remove the smallest
particles. Rainey said the material could be
used as a disposable filter cartridge in face
masks.
This material would be relatively inexpensive to
produce and would therefore be suitable for
single-use. The cellulose nanofiber component is
made from waste plant material, such as sugar
cane bagasse and other agricultural waste
products and is, therefore, biodegradable. It
can be made using relatively simple equipment,
and so we can quickly produce large quantities
of the material.
“We have established proof-of-concept as a
nanoparticulate filtration material and we are
currently seeking industry partners," said
Rainey.

Changing Guidelines Relative to PPE Use in
Hospitals
The specifics of PPE use
have been controversial
since the pandemic first hit US shores. But once
the Centers for Disease Control and Prevention
(CDC) issued the recommendation two weeks ago
that everyone wear masks in public, hospital PPE
policies began shifting rapidly. Many providers
welcomed the change, and the number of
healthcare workers being
reprimanded for using their own PPE
appears to have plummeted.
But rolling out new policies in the midst of a
pandemic has created new problems: Frontline
providers aren't always clear on current
protocols. Institutional instructions on donning
and doffing a wider variety of PPE sometimes lag
behind or are completely lacking. And some
medical organizations, including
The American Association of Nurse Attorneys,
have urged the CDC to reconsider its loosened
standards, which allow for the use of bandanas
in lieu of masks, saying they "will most likely
result in the increased spread of the virus."
"Hospitals all over have greatly changed their
practices around PPE use in response to existing
shortages," said Eric Toner, MD, a senior
scholar at the Johns Hopkins Center for Health
Security who conducted
a new analysis
on how much PPE may be needed. "And these will
continue to evolve in response to local supply
and demand mismatches."
More Accurate Temperature Measurement Needed
I &E Technologies
have been deploying hundreds of
EBT (Elevated Body Temperature) Detection
Systems in food plants, manufacturing plants,
office buildings, hospitals, airports,
retirement facilities, amusement parks, etc.,
for over a month now across the country to help
screen individuals. While these thermal imaging
instruments are not medical devices and do not
replace conventional medical testing, they can
be used to give an early indication when
evaluating or screening a large population and
are quick and effective at a safe distance.
According to Eric Fritz, I.E, president “Systems
that claim to effectively scan groups of people
at once as they pass by the camera, we believe
will lead to a less accurate screening process
and ultimately could put the facility and it's
personnel at risk of "false-positives" or worse,
"false-negatives". Due to many parameters
that affect temperature measurement accuracy
with any thermal imaging camera, it is important
that the targets remove any glasses to open the
view to the tear ducts, the cameras are in
focus, the target is at the correct distance,
the camera has the correct resolution and field
of view for the distance, the camera has the
correct frame rate, the system collects
accurate, repeatable, and reliable temperature
data, and the system accounts for other elements
like environmental temperatures inside/outside,
stabilization of the target, etc., to minimize
interpretation of the data being collected.
Danone Closes Wuhan Plant but has High
Production Rates Elsewhere
The French-based beverage company behind Evian
and other bottled water has closed its factory
in Wuhan, China - its second largest market - as
a result of COVID-19.
But other plants are compensating .
Danone SA sales in the first quarter rose,
driven by Europe and North America, while it
withdrew full-year guidance due to the
coronavirus.
The French food company said sales came in at
6.24 billion euros ($6.78 billion) compared with
EUR 6.14 billion in the previous year period.
Sales rose 1.7% on a reported basis and 3.7% on
a like-for-like basis.
"First-quarter like-for-like sales growth is
ahead of the expectations set by the company
earlier in the year," Danone said.
The growth was partly attributed to a sales rise
in March, boosted by the short-term effects of
both a shift to at-home consumption as well as
pantry loading in Europe and North America.
Danone's water division registered a decline of
6.8% like-for-like, while the essential diary
and plant-based business grew 4.6%. Specialized
nutrition recorded a growth of 7.9% on a
like-for-like basis.
Danone virus protection measures at plants
include
§
Hourly workers will receive a premium payment
equivalent to 15% of their base hourly rate for
all hours worked.
§
If a worker contracts coronavirus or must stay
isolated at home because they have been in close
contact with someone with the virus, they are
eligible for up to 80 hours of paid quarantine
leave.
§
Workers who have childcare needs are eligible to
utilize any state, city or provincial paid sick
leave where applicable.
Danone Indonesia is producing bottles for hand
sanitizers.
Restaurant Ventilation Systems Spread Virus
In an
early-release research letter
in the journal Emerging Infectious Diseases,
researchers said they found that 10 people who
were sitting near one another at a restaurant in
China in January got COVID-19, and that it
likely spread because of the restaurant's air
conditioner.
·
Three seemingly healthy families were struck by
COVID-19 after dining at neighboring tables in a
windowless restaurant in Guangzhou, China, in
January.
·
Researchers studying the case think that the
restaurant's air conditioner blew the viral
droplets of one person who was asymptomatic
farther than they might have normally gone. Nine
other people across the three families later got
sick.
·
The researchers described their findings in an
early-release research letter published
in the journal Emerging Infectious Diseases
earlier this month.
·
It's a frightening prospect for people who are
trying to keep a healthy distance from others.
However, in a potentially hopeful finding for
the locked-down restaurant industry, none of the
73 other diners and eight employees in the
restaurant at the time got sick, the researchers
said.
·
"To prevent the spread of the virus in
restaurants, experts recommend increasing the
distance between tables and improving
ventilation.
·
For the struggling restaurants desperate to
reopen in the coming months, the researchers'
findings are evidence that work will not just
return to normal after the pandemic, but there
might be ways to limit the risk of spreading the
virus. There will likely be caps on how long
patrons can spend eating, restaurants will
operate at lower capacity, air conditioning or
heating may have to stay off, and employees
might be advised to wear masks.
·
McIlvaine comes to a different conclusion
relative to the air conditioning. HEPA filters
should be installed and air flow directed from
ceiling to floor and designed as much as
possible to capture any virus clouds and remove
the virus as it passes through the AC system.
Turning off the air conditioning system will
still allow virus clouds to follow air currents.
The result could have been transmission of the
infection to D,E, and F
tables and even more infections.
More Coronavirus Outbreaks at Meatpacking Plants
Than Previously Estimated
And it could get worse. More than 150 of
America’s largest meat processing plants operate
in counties where the rate of coronavirus
infection is already among the nation’s highest,
based on the media outlets’ analysis of
slaughterhouse locations and county-level
COVID-19 infection rates.
These facilities represent more than 1 in 3 of
the nation’s biggest beef, pork and poultry
processing plants. Rates of infection around
these plants are higher than those of 75% of
other U.S. counties, the analysis found.
And while experts say the industry has thus far
maintained sufficient production despite
infections in at least 2,200 workers at 48
plants,
there are fears that the number of cases could
continue to rise and that meatpacking plants
will become the next disaster zones.
"Initially
our concern was long-term care facilities,"
said Gary Anthone, Nebraska's chief medical
officer, in a Facebook Live video Sunday. “If
there's one thing that might keep me up at
night, it's the meat processing plants and the
manufacturing plants."
Workers can stand too close together in certain
areas of a meat packing facilities, enabling the
spread of coronavirus. This is a look inside a
chicken processing plant, but the process is
similar no matter what type of meat is being
processed. |
