The USDA is reporting that
cattle prices continue under
pressure from large supplies. Price
pressure will continue as summer
weather tends to reduce demand following the May-
June period of strong holiday demand, and as
seasonal production rises.

Anticipated prices should average in the low to
mid $60 range this summer. Prices are expected to
strengthen in late summer.

Stocker-feeder cattle prices continue under
pressure from feedlot financial losses since Spring


2001. Poor to uncertain forage prospects in most
areas will exacerbate the trend.

Hay prospects have declined with most areas
of the nation too dry, but some areas have been too
wet. Florida has been an exception with good July
moisture, but armyworms have been active.

Limited irrigation water may also hold down
forage production in a number of usually
dependable areas. Florida is fortunate not to be
included in this grouping.

Most of the feedlot placements have been
heavier feeder cattle, but placement numbers have
declined from April 2001. The heavier weight
placements will add to the already large number of
feedlot inventories that likely will be marketed by
the end of Summer 2002.

Weather related conditions will affect breeding
and sale decisions in a few months, and by default,
beef supplies this fall and in 2003. Areas with good
moisture and forage prospects will likely have a
higher retention rate of breeding age stock.

Second and third quarter 2002 beef production
is expected to rise four and three percent,
respectively, over the weather reduced levels of the
same period in 2001. First quarter 2002, production
levels were up three percent.

Cattle slaughter is only modestly different
from a year earlier. However, improved feeding
conditions in 2002 have resulted in sharply
increased commercial dressed slaughter weights.

First quarter 2002 weights were up 31 pounds.
Second quarter weights are estimated to be up 20 to
25 pounds.

Retail beef prices are currently well under the
same period last year and are predicted to decline
through the summer. Increased supplies of beef,
especially higher grading beef, and larger supplies
of competing meats have held down retail prices.

Beef exports have held up well against the
depressed level of a year earlier when U.S. beef was
priced out the export market. Beef is predicted to

September 2002 3

rebound about one percent after declining eight
percent last year. The sluggish worldwide economic
growth will impede better performance.

Deer Flies a

Biting Problem?

Oddly, "Trolling" May Be Just The Ticket

The deer flies are so bad at Dick Coski's farm
near Lake Erie in northeast Ohio that he used to get
covered in bites mowing his small field. Hunting for
a solution, the retired Social Security claims
representative found a Web site about a curious deer
fly-control device invented by a University of
Florida scientist. The bright blue plastic flowerpot,
covered with sticky material and suspended upside-
down on a pole, was said to entice and capture the
pesky bugs. It looked goofy. But when Coski, 70,
rigged up a similar device and stuck it on the front
of his John Deere, he was amazed at the result.

"The deer flies didn't even look at me they
were all buzzing around that dam flowerpot," Coski
said. "My sister-in-law's husband is one of those
hard-nosed Englishmen, and he didn't believe me.
He came up from Columbus and took a ride on my
lawn tractor, and he couldn't get over it."

Insects are strange creatures that sometimes
prove vulnerable to even stranger methods of
elimination. That seems to be the lesson of the
curiously effective deer-fly trap invented by Russell
Mizell, a professor of entomology at UF's Institute
of Food and Agricultural Sciences. Mizell's article
about the trap appeared in the June issue of the
journal Florida Entomologist, although it previously
was featured on an IFAS pest-control Web site.

Mizell, who is based at UF's North Florida
Research and Education Center in Quincy, said he
first launched the research several years ago as a
high school science project with his son, but "it got
so interesting, I just kept doing it."

He was familiar with reports that African tsetse
flies are drawn to silhouettes of hoofed animals. He
also had noticed that deer flies often buzzed the
rearview mirrors on his truck as he drove along the
gravel driveway to his Jefferson County home. Deer
flies are so-called ambush predators: They wait for

prey to walk by rather than actively searching for it,
so they are highly attracted to movement.

With this in mind, Mizell and his son decided
the best way to snare deer flies likely was to "troll"
for them from a slow-moving vehicle. Working in
the spring and summer when deer flies are most
prominent, they "did all kinds of crazy things" to try
to discover what kind of trap worked best, he said.

The Mizells first tried draping their 1992
Dodge Dakota pickup with white plastic covered
with black silhouettes of various shapes painted
with Tanglefoot, a commercially available sticky
spray for insects. But the deer flies snubbed the
silhouettes. Theorizing that three-dimensional
shapes would work better because they had more
surface area, the Mizells built a test platform on
their truck hood that could troll seven different
shapes at once. They ambled along in deer fly-
infested countryside for set periods of one to five
minutes, testing sticky pyramids, squares, balloons,
plant containers and other shapes, then counting
immobilized prey. They also tried black, tan, blue
and shapes of other colors suspended from various

After numerous experiments, the trap that
wooed the most deer flies proved to be a 6-inch
flowerpot painted bright blue capturing as many as
30 deer flies in a one-minute test. It worked best
when suspended three to six feet above the ground
and trolled no faster than 10 feet per second. The
capture rate was 35 percent to 50 percent higher
than for other shapes, Mizell said.

Mizell said he isn't sure what it is about this
color/shape/speed combination that makes it so
irresistible to the hapless deer flies. It could be that
something about it appeals to their genetic memory
of a tasty but extinct animal. But more likely, he
said, the blue contrasts sharply with the
predominant background of green foliage, making it
easy for the deer flies to zero in on. The optimum
size and height, meanwhile, are close to the head of
a person or large animal.

The traps are remarkably effective, Mizell said.
"Many times after running the traps through an area,
we found there were no deer flies left," he said.


September 2002 5

"You trap them out for a short period until they
repopulate the area."

The traps do not have to be suspended from a
vehicle they also work when attached to a baseball
cap and trolled by the hat's wearer.

After hearing Mizell give a presentation on his
project, Wendy Meyer, a staffer at UF's Tropical
Research and Education Center in Homestead,
decided to try out such a rig to combat the deer flies
that attacked her during her field research. Wanting
to avoid wearing a flowerpot, she used a blue soda
cup painted with Tanglefoot.

"It worked wonderfully," she recalled. "I'd
come back in, and I'd have 10 or 12 flies on my cap
and none that had annoyed me."

Despite its effectiveness, it is doubtful the trap
ever will gain widespread appeal for personal
protection. As Meyer noted, its aesthetic appeal
leaves something to be desired.

"The thing is, it looked really silly, so everyone
laughed at me when I wore it, but then they
complained about getting bitten by deer flies," she
said. "It's a hard sell to get people to try it, but it
really did work."

Veneman Releases State

Funding Allocations for

Environmental Quality

Incentives Program

SU DA Agriculture Secretary Ann M.
U Veneman announced that the
additional $227 million for the
Environmental Quality Incentives
Program (EQIP) has been released
to all states, Puerto Rico and the Pacific Basin. This
is an important step towards implementing an
improved, streamlined program that includes
changes authorized in the 2002 Farm Bill and
outlined in the July 24 Federal Register notice.
Florida will receive $5,088,162.

Through this allocation, Natural Resources
Conservation Service (NRCS) state offices will
receive allocated funding needed to provide
financial and technical assistance to farmers,
ranchers and tribes through EQIP for conservation
practices that improve soil, water and air quality;
wildlife habitat; and surface and ground water
conservation on eligible agricultural land, including
livestock operations.

"These funds will enable farmers and ranchers
to enhance and protect our nation's soil, air and
water resources for the future by implementing
sound conservation practices today," said Veneman.
"Farmers and ranchers are the best stewards of the
land and this Administration continues its strong
commitment in providing additional tools to
enhance conservation efforts on working

Key factors used to determine the distribution
include acres of cropland, acres of irrigated
cropland, acres of rangeland, acres of tribal lands,
number of animals and tons of animal waste

Veneman announced earlier this month that an
additional $200 million is being provided for
general enrollment for EQIP in FY 2002 and up to
an additional $25 million of EQIP funds in FY 2002



6 September 2002
will provide technical and financial assistance for
ground and surface water conservation.

Deaths of Three Deer-

Eating Hunters Being

Investigated for Possible

CWD Link

Here's some potentially scary news relating to
chronic wasting disease from Reuters. The deaths of
three Wisconsin hunters back in the 1990s who
regularly ate wild game are being investigated for
any possible connection to chronic wasting disease -
- a fatal brain disease afflicting the state's deer herd.
Eight other states have reported cases of CWD in
deer and elk herds.

Two of the deaths were attributed to
Creutzfeldt-Jakob disease, a rare disorder that has
been tied in Europe to eating meat from cattle
infected with bovine spongiform encephalopathy, or
mad cow disease, according to the report. The other
man died from Pick's disease, a more common brain
disease. Scientists from the U.S. Centers for Disease
Control and Prevention in Atlanta will help
investigate these deaths.

What is chronic wasting disease?

CWD is an untreatable, fatal neurological
disease found in deer and elk in certain
geographical locations in North America. The
disease belongs to a family of diseases known as
transmissible spongiform encephalopathies or prion
diseases. The disease attacks the brain and neural
tissue of infected deer and elk.

Although the exact mechanism is not known,
CWD is believed to be spread by the agent
responsible both by direct animal-to-animal contact
and indirectly via the soil or other contact surfaces.
It is thought that the most common mode of
transmission from an infected animal is via saliva,
feces, and urine.

No reason to panic

The bad news is that CWD is similar to mad
cow disease in cattle and scrapie in sheep, but the
good news is there is no known relationship
between CWD and any other TSEs of animals or
people. To date, CWD has not been shown to infect
humans or cattle, but the World Health
Organization has advised against eating venison or
any part of an animal showing signs of the disease.
This warning has raised red flags about venison
stored in home freezers throughout the state of
Wisconsin, a prime state for deer hunting that
generates roughly $1.5 billion annually, according
to Reuters.

Wisconsin plans to eradicate the deer herd
from an area where more than 12 animals have
tested positive for the disease and then test the

Human West Nile Virus
Case Confirmed

Medical Alert Extended to Include Lake,
Marion, Orange, and Sumter Counties

The Florida Department of Health (DOH)
announced that the first human West Nile (WN)
virus infection of 2002 in Florida has been
confirmed. The patient is a resident of Sumter
County, but had exposure to mosquitoes in
Louisiana prior to illness. Due to the uncertainty
regarding where the infection was acquired, and due
to additional WN detections in animals, a medical
alert is being issued for Lake, Marion, Orange and
Sumter counties. Medical alerts were issued last
week for Escambia and Volusia counties.

"Even though the risk of contracting West Nile
virus and other mosquito-borne viruses by humans
is low, people need to use protective measures to
reduce their risk of getting the disease," said DOH
Secretary John O. Agwunobi, M.D., M.B.A. He
added, "It is important to take measures to guard
against mosquito bites." Agwunobi recommends the

Avoid outdoor activities at dusk and dawn
when mosquitoes are likely to be active and biting;
If you must be outdoors when mosquitoes
are active, cover up by wearing shoes, socks, long
pants and a long-sleeved shirt;
Use mosquito repellant containing DEET
according to manufacturer's directions; and
Eliminate stagnant water in birdbaths and
any other receptacles in which mosquitoes might

The Department of Health laboratories provide
testing services for physicians treating patients with
clinical signs of mosquito-borne (arboviral) disease.
These signs may include headache, fever, fatigue,
dizziness, weakness and confusion. Physicians
should submit serum and, if available, cerebrospinal
fluid samples to either the Tampa or Jacksonville
Department of Health laboratories. People over the
age of 50 are at the greatest risk of having severe
disease from an arbovirus infection.

September 2002 7
DOH continues to conduct statewide
surveillance for arboviruses, including WN, eastern
equine encephalomyelitis (EEE) and St. Louis
Encephalitis (SLE). Residents of Florida are
encouraged to report dead birds by calling the West
Nile Virus Hotline at 1-800-871-9703, or via the
Web site http://www.wld.fwc.state.fl.us/bird/.

Linked to E.
Coli 0157:H7


Where's the Outrage Now?

Just in case you missed this news -- and there's
a good chance you might have since little has been
published on it that the Meatingplace.com is aware
of -- the Food and Drug Administration is warning
consumers not to consume Spokane Produce brand
romaine lettuce because this product was associated
with an outbreak of E. coli 0157:H7 at a
cheerleading camp in Washington state in mid July.

FDA is urging consumers to throw this product
out. The latest reported illness associated with this
outbreak was on July 19, according to FDA. The
romaine lettuce, which is sold under several
different brand names, is known to be packaged in
5-pound bags labeled "Romaine Toss" and was


8 September 2002
distributed by Food Services of America to
restaurants and institutions in the Spokane area.

The product has a shelf life of two weeks. To
date, the outbreak has only involved exposure to
romaine lettuce packaged in these 5-pound bags.
The romaine lettuce may also be sold at retail
establishments in various size packages.

Twenty-nine individuals at the cheerleading
camp have been confirmed to have E. coli
0157:H7. Other illnesses in Washington state are
being investigated.

This situation was discovered when many
individuals at the camp became ill, according to
FDA. The FDA is working with the Spokane
Regional Health District, Washington State
Department of Agriculture, Washington State
Department of Health and other agencies to
determine the cause and scope of this problem.
FDA is telling consumers who bought such a
product to check with the place of purchase to
ensure that they do not consume Spokane Produce
brand romaine lettuce until this health emergency is
resolved, the news release added.

Where's the outrage?

There's no satisfaction in knowing that the
source of contamination was a non-meat product.
However you look at it, it's a tragedy. But isn't it
strange how E. coli outbreaks in meat products
result in a media, consumer activist and anti-meat
activist frenzy while outbreaks from non-meat foods
go largely unnoticed?

"If this would have involved meat, it would hit
the front page [in every major newspaper] and be on
the TV news," complained one well known meat
industry veteran to the Meatingplace.com via e-
mail. "Activists would be screaming for tighter
inspections, claiming a link to the inspection
authorities and all that other junk. Where are they
now -- now that it involves one of their precious
vegetables -- the 'good-for-you' foods, the healthy
food, and a non-meat item? Hypocrites! Now I feel

Thanks, meat industry veteran, for blowing off
steam. I feel better now, too.

House Ag Committee to

Hold Hearings on

Livestock Industry


Following-up on a pledge at the completion of the
Farm Bill, House Agriculture Chairman Rep. Larry
Combest (R-Texas) has asked state and national
producer groups, agricultural economists, national farm
groups, packers and the Secretary of Agriculture to
"respond to specific questions that will lay the
foundation for hearings on the current state of livestock

The goal of the probe is to understand the potential
impact -- positive and negative -- government
intervention would have on the livestock marketplace.
An amendment was included in the Senate version of the
Farm Bill that would have prohibited packer ownership,
feeding or control of livestock within 14 days of
slaughter, a provision not included in the final bill. Since
then, as the political debate has persisted, bills have been
introduced that would ban packer ownership from
owning livestock, alter the use of forward contracting
and limit the use of captive supplies of livestock.

While a deadline has not been set for comments
and answers to be submitted, the comments will likely
serve as "foundation for hearings" in the near future. To
view the list of questions or to submit answers, visit
