Proposes New Guidelines for Safe Produce |
|
With the publication
of a draft guideline document, the U.S. Food and Drug Administration
(FDA) announced an effort to minimize microbial food safety hazards
common to the processing of most "ready-to-eat" fresh-cut fruits
and vegetables. The draft "Guide to Minimize Microbial Food Safety
Hazards of Fresh-cut Fruits and Vegetables" provides recommendations
for produce processors in several key areas -- including personnel
health and hygiene; training; building and equipment; sanitation
operations, and processing controls such as packaging, storage and
transport.
FDA recommends
that produce processors encourage the adoption of safe practices
both in their own operations and in the processes of partners throughout
the supply chain. From produce growers, packers and distributors
to retailers, food service operators and consumers, all those involved
with the process of bringing fresh produce to the table are urged
through the new guidelines to improve cleanliness and overall health
safety conditions. Recommended practices include:
- Establishment
of policies in which individuals must report any active case of
illness to supervisors before beginning work and training.
- Training
programs for supervisors to recognize typical signs/symptoms of
infectious disease and refusing to allow an employee to work with
any aspect of fresh or fresh-cut produce, processing equipment
or tools until symptoms have disappeared, the wound has healed
and/or the infectious disease has been treated.
Additionally,
consumers are urged to reduce their risk of illness exposure by
following safe fresh-cut produce handling practices, including thorough
washing of all produce, proper refrigeration routines, using only
clean hands, utensils and dishes in food preparation and awareness
of "use by" dates.
FDA will accept
public comments on the draft guidance for 60 days.

| Ground
Water Awareness Week Begins March 12 |
|
Stressing proper
water well maintenance and yearly water testing, the National Ground
Water Association (NGWA) will celebrate its annual Ground Water
Awareness Week beginning March12. The key message of NGWA's week:
"Time to Schedule Your Annual Water Well Checkup".
According
to NGWA, proper operation of wells through scheduled check-ups is
essential to safe drinking water. NGWA advises that a licensed
and/or certified water well contractor should conduct routine well
checkups. The maintenance routine should include the following:
- A flow test
to determine system output, along with a check of the water level
before and during pumping (if possible), pump motor performance
(check amp load, grounding, and line voltage), pressure tank and
pressure switch contact, and general water quality.
- An inspection
of well equipment to assure that it is sanitary and meets local
code requirements.
- A test of
your water for coliform bacteria, nitrates, and any additional
contaminants of local concern. Other typical additional tests
are those for iron, manganese, water hardness, sulfides, and other
water constituents that cause problems with plumbing, staining,
water appearance, and odor.
Approximately
half the U.S. population receives its drinking water from private
wells, and more than 90 percent of the world's fresh water supply
originates from ground water, according to NGWA.
Ground Water
Awareness Week includes cosponsors from the Automotive Oil Change
Association and promotional partners U.S. Geological Survey, U.S.
Environmental Protection Agency, Centers for Disease Control and
Prevention and The Groundwater Foundation.

Aims at Salmonella Reduction in Meat and Poultry Industry |
|
The U.S. Department
of Agriculture (USDA) has announced a new initiative to reduce Salmonella
contamination in raw meat and poultry by intensifying testing efforts
on processing facilities. The new program will focus on improved
and expedited reporting of test results. Since 2002, there has
been a steady increase in Salmonella in broiler chickens,
according to the USDA's Food Safety and Inspection Service (FSIS).
Approximately 16% of broiler samples tested by USDA tested positive
for Salmonella in 2005.
Each year
in the U.S. over one million cases of Salmonella poisoning
are reported and 500 Americans die from the complications of the
infection.
Initially, FSIS
resources will concentrate on facilities reporting the highest levels
of Salmonella, providing sample-by-sample test results to
facilities as soon as they become available. Currently, firms receive
results after a full set of samples is completed, which, in the
case of broilers, means after 51 consecutive days of sampling. By
providing short term results reporting for each sample, processing
facilities will be able to assess slaughter dressing procedures
immediately, making certain adequate pathogen reduction protocols
are being followed.
In addition,
the USDA also plans to identify Salmonella serotypes more
quickly so it can notify meat firms and investigate illness outbreaks
in coordination with health other agencies. Serotypes are used to
trace the sources of outbreaks of food borne disease by matching
pathogen strains found in patients with strains found in foods.
The FSIS collects
and tests samples of seven categories of products: broilers, market
hogs, cows and bulls, steer and heifers, ground beef, ground chicken,
and ground turkey. For all product categories combined in 2005,
they found Salmonella in 5.7% (2,322) of the 40,714 samples tested.

Poultry Products, 1998-2005", please go to:

| Membrane
Filtration for LT2 Rule in New EPA Manual |
|
The
U.S. Environmental Protection Agency (EPA) has issued a new guide
to help utilities and states comply with the Long-Term 2 Enhanced
Surface Water Treatment Rule (LT2) to control microbial pathogens.
The EPA-issued manual, Membrane Filtration Guidance Manual,
is provided as an option for drinking water utilities that need
to install treatment processes in compliance with the new LT2 rule,
according to the agency.
The
LT2 rule requires utilities using surface water to carry out additional
monitoring for pathogens and, if necessary, take additional treatment
steps. Membrane filtration has gained increased acceptance over
the years because of its effectiveness against chlorine-resistant
protozoa such as Giardia and Cryptosporidium, while
limiting the formation of disinfection byproducts (DBPs), according
to EPA.
Based
on the levels of pathogens found in the monitoring, a utility would
be placed in one of four risk-based "actions bins" under the rule,
with Bin 4 requiring the most treatment. The bin also would determine
which treatment methods a utility could use from a "toolbox of actions"
included in the LT2 rule. Among the toolbox items are source water
protection measures, use of pretreatment, using an alternative source
of water, use of disinfectants such as chlorine dioxide and ultraviolet
light, and the use of various types of filters, including membrane
filters.
Membrane filtration processes include microfiltration, ultrafiltration,
nanofiltration, reverse osmosis, and membrane cartridge filtration,
according to EPA. Each of these processes uses a membrane barrier
that allows water to pass through but removes contaminants, including
Cryptosporidium and Giardia.
