[Docket No. FSIS 2007-0018]
Disposition of Hogs and Chickens From Farms Identified as Having
Received Pet Food Scraps Contaminated With Melamine and Melamine-
Related Compounds and Offered for Slaughter
AGENCY: Food Safety and Inspection Service (FSIS), USDA.
ACTION: Notice and request for comments.
-----------------------------------------------------------------------
SUMMARY: The Food Safety and Inspection Service (FSIS) is publishing
this notice to articulate its position on the slaughter for human food
of hogs and chickens from farms identified as having purchased or
otherwise received pet food scraps that contain melamine and melamine-
related compounds. The contaminated pet food scraps were used to
supplement animal feed on farms in several States. The results of an
interim safety/risk assessment indicate that, based on currently
available data and information, the consumption of pork, poultry, eggs,
and domestic fish products from animals inadvertently fed animal feed
contaminated with melamine and melamine-related compounds is very
unlikely to pose a human health risk.
Based on the findings of the interim safety/risk assessment, as
well as the results of validated testing for melamine concentration
that has been conducted on tissue samples of hogs and chickens exposed
to the adulterated feed, FSIS has determined that pork and poultry
products from all animals identified as having been fed animal feed
containing contaminated pet food scraps are ``not adulterated'' and are
thus eligible to receive the mark of inspection. All such animals that
were being held on farms have been released and may be offered for
slaughter for human food.

SUPPLEMENTARY INFORMATION:
Background
FSIS is responsible for ensuring that meat and poultry products are
safe, wholesome, and accurately labeled. FSIS enforces the Federal Meat
Inspection Act (FMIA) (21 U.S.C. 601 et seq.) and the Poultry Products
Inspection Act (PPIA) (21 U.S.C. 451 et seq.). These two statutes
require Federal inspection and provide for Federal regulation of meat
and poultry products prepared for distribution in commerce for use as
human food.
Under the Acts, FSIS inspection personnel apply the mark of
inspection to meat and poultry products if they find upon inspection
that these articles are not adulterated (21 U.S.C. 455, 457; 21 U.S.C.
604, 606, 607). The Acts prohibit the sale or transportation in
commerce of meat and poultry products capable of use as human food that
are adulterated or misbranded or that have not been inspected and
passed (21 U.S.C. 458 (a)(2); 21 U.S.C. 610(c)). The Acts also
authorize FSIS to take certain actions to remove from commerce meat or
poultry products that the Agency has reason to believe are adulterated
or misbranded, or that have not been inspected (21 U.S.C.
467(a),467(b); 21 U.S.C. 672,673). Under the Acts, a meat or poultry
product is adulterated if, among other circumstances, it bears or
contains any poisonous or deleterious substance that may render it
injurious to health (21 U.S.C. 453(g)(1), 601(m)(1)); it bears or
contains (by reason of administration of any substance to the live
animal or poultry, or otherwise) any added poisonous or added
deleterious substance which may in the judgment of the Secretary render
it unfit for human food (21 U.S.C. 453(g)(2), 601(m)(2)); if it is for
any reason unsound, unhealthful, unwholesome, or unfit for human food
(21 U.S.C. 453(g)(3), 601(m)(3)); or if it has been prepared, packaged,
or held under insanitary conditions whereby it may have been rendered
injurious to health (21 U.S.C. 453(g)(4), 601(m)(4)).
On April 26, 2007, FSIS and the U.S. Food and Drug Administration
(FDA) announced that hogs on farms in certain States had consumed
animal feed supplemented with pet food scraps contaminated with
melamine and melamine-related compounds. On April 30, 2007, the
agencies announced that chickens on certain farms in Indiana had also
been fed poultry feed supplemented with melamine-contaminated pet food
scraps. FSIS learned of the adulterated feed during the course of an
ongoing FDA investigation of pet food associated with illnesses and
deaths in cats and dogs. The pet food was found to contain melamine or
melamine-related compounds (cyanuric acid, ammelide, and ammeline).
Based on the available science and information, FDA investigators
believed that the combination of melamine and melamine-related
compounds, particularly cyanuric acid, caused the formation of crystals
in the kidneys that led to kidney failure in some of the pets that had
consumed the adulterated pet food. The investigation found that the
source of the melamine and melamine-related compounds in the pet food
was products, labeled as rice protein concentrate and as wheat gluten,
which had been imported from China. The investigation also revealed
that scraps from the adulterated pet food had been sold to hog and
chicken producers and feed mills, where they were used to supplement
animal feed. FDA then notified FSIS of its findings regarding animal
feed.
When FSIS and FDA announced that they had learned that hog and
chicken farms in various States had purchased or otherwise received pet
food scraps contaminated with melamine and melamine-related compounds,
the agencies noted that some of the hogs and chickens that had consumed
feed supplemented with the contaminated pet food scraps may have been
slaughtered and their products distributed in commerce. At that time,
the agencies also explained that they would work with States and
industry to take the appropriate action with regard to the disposition
of these products.
Actions Taken Based on Data Concerning the Consumption of Feed
Supplemented With Adulterated Pet Food
When FSIS learned that hogs and chickens had consumed feed that had
been supplemented with pet food scraps contaminated with melamine and
melamine-related compounds, the Agency concluded that risk to human
health from consuming pork or poultry products from these animals was
likely to be very low. This conclusion was based on information that
indicated that the concentration of melamine and melamine-related
compounds in the adulterated feed was likely very low due to dilution.
However, because the animal feed in question was adulterated, and given
the information that was available at the time, FSIS could not rule out
the possibility that pork and poultry products produced from hogs and
chickens that consumed the adulterated feed could also be adulterated.
Therefore, all animals that had been identified as having consumed feed
supplemented with pet food scraps contaminated with melamine and
melamine-related compounds and that were not yet offered for slaughter
were placed under State quarantine or voluntarily held by the
producers.
In a press release issued on May 7, 2007, FDA and FSIS announced
the results of a human health risk assessment estimating the risk to
human health from melamine and melamine-related compounds through the
consumption of edible animal products derived from poultry, pork, and
fish. This human health risk assessment has since been updated with new
information and is hereafter referred to as the interim safety/risk
assessment. The interim safety/risk assessment concludes that, based on
currently available data and information, the consumption of pork,
poultry, eggs, and domestic fish products from animals inadvertently
fed animal feed contaminated with melamine and melamine-related
compounds is very unlikely to pose a human health risk. In a Notice of
Availability published in this issue of the Federal Register, FDA is
announcing the availability of this ``Interim Melamine and Analogues
Safety/Risk Assessment.''
In the May 7, 2007, press release, FDA and FSIS also announced that
several samples of feed from farms identified as having received
contaminated pet food scraps had been tested by Federal laboratories or
state laboratories using approved methods and the tests did not detect
the presence of melamine and melamine-related compounds. The negative
tests most likely reflected the fact that, because of dilution, the
amount of melamine and melamine-related compounds present in the feed
was so small that the compounds were no longer detectable by the
approved testing method.
After considering the new information presented in the interim
safety/risk assessment, together with the recent test results that
found that melamine concentrations in some of the adulterated feed was
below the level of detection, FSIS determined that it would be
appropriate at that time for the Agency to permit, under certain
conditions, hogs and chickens that had been identified as having
consumed adulterated feed to be offered for slaughter. Therefore, at
that time, FSIS decided to allow hogs and chickens identified as having
consumed adulterated feed to be offered for slaughter for human food if
the feed had
[[Page 29947]]
been tested by a Federal laboratory or state laboratory using approved
methods and the test did not detect the presence of melamine and
melamine-related compounds. FSIS concluded that under these conditions,
FSIS would be able to find that pork and poultry products from animals
that had consumed adulterated feed were ``not adulterated'' and thus
eligible to receive the mark of inspection.
At that time, hogs and chickens that had been identified as having
consumed feed that had tested positive for melamine and melamine-
related compounds, as well as animals that had been identified as
having consumed feed supplemented with contaminated pet food scraps but
none of the adulterated feed was available for testing, continued to be
held under State quarantine or voluntarily by the producers. The
disposition of these animals was to be determined on the basis of
information from on-going investigations of hogs and chickens
identified as having consumed adulterated feed. As part of these
investigations, samples of animal feed, urine, and tissues were
collected and analyzed for melamine concentration.
In addition, based on the information that was available at the
time, including information in the interim safety/risk assessment, FSIS
concluded that it did not have sufficient evidence to demonstrate that
the pork or poultry products that had already been distributed in
commerce were injurious to health, unfit for human food, or otherwise
adulterated under the FMIA or PPIA. Therefore, FSIS decided that it
would not take action to remove from commerce any pork or poultry
products that were produced from hogs and chickens that had consumed
feed supplemented with pet food scraps contaminated with melamine and
melamine-related compounds, but that had been slaughtered and processed
prior to May 7, 2007. Thus, FSIS did not request that companies
voluntarily recall the affected products from commerce. Information on
the safety of pork and poultry from animals inadvertently fed
adulterated feed that has become available since that time and is now
reported in the interim safety/risk assessment further affirms this
decision.
Actions Taken in Response to Tissue Test Results
As discussed above, as part of the on-going investigations of hogs
and chickens identified as having consumed feed supplemented with pet
food scraps contaminated with melamine and melamine-related compounds,
samples of animal feed, urine, and tissues were collected and analyzed
for melamine concentration. Information from these ongoing
investigations is being used to examine the relationship between
melamine levels in feed and the levels in animal tissues, assess the
changes in melamine level in the animals over time, and compare the
level found in animals and feed with concentrations that could pose a
risk to humans.
On May 12, 2007, FSIS completed its validation of the methodology
used to detect melamine concentration in pork tissues. The current
analytical method for measuring melamine concentrations in pork can
screen for melamine concentrations in pork tissue at 50 ppb and above.
It should be noted that 50 ppb represents a conservative estimate for
the method employed. All pork samples analyzed to date have had
melamine concentrations below the validated 50 ppb screening level
(ranges measured were estimated to be from 9 to 12 ppb), including
samples from hogs identified as having consumed the highest percentage
of pet food scraps, as to which the hog feed was composed primarily, if
not exclusively, of the contaminated pet food scraps.
On May 15, 2007, USDA issued a press release that announced that
results of testing conducted on tissue samples from hogs confirm that
meat from hogs fed animal feed supplemented with pet food scraps
containing melamine and melamine-related compounds is safe for human
consumption. The press release also announced that hogs being held on
farms because they had consumed adulterated feed would be released and
approved for slaughter and processing into human food. The press
release explained that the interim safety/risk assessment had been
updated to reflect the melamine concentration for pork of 50 ppb
screening level. The conclusion of the interim safety/risk assessment
did not change.
Subsequent to the development of the validated testing method for
hog tissue, FSIS validated the test methodology used to screen for
melamine concentration levels in poultry tissue at the 50 ppb level.
All poultry tissue samples analyzed to date have had melamine
concentrations below 50 ppb. On May 18, 2007, a USDA press release
announced that the validated test for poultry confirms the safety of
eating meat from chickens fed poultry feed supplemented with pet food
scraps containing melamine and melamine-related compounds. The press
release also announced that, based on the results of the tests,
approximately 80,000 birds that were being held on farms in Indiana
were to be released and approved for slaughter and processing into
human food.
Thus, as announced on May 15, 2007, regarding hogs, and on May 18,
2007, regarding chickens, FSIS has decided to allow all animals
identified as having consumed pet food scraps contaminated with
melamine and melamine-related compounds to be offered for slaughter.
Based on the results of the measured melamine concentration in pork and
poultry tissue samples from animals exposed to adulterated feed,
together with the findings of the interim safety/risk assessment, FSIS
had determined that it is able to find that pork and poultry products
from animals that have consumed feed that contains pet food scraps
contaminated with melamine and melamine-related compounds are ``not
adulterated'' and thus eligible to receive the mark of inspection as
required under the FMIA and PPIA.
At the time of publication of this Federal Register notice, all
hogs and chickens that were previously under State quarantine or being
held voluntarily by the producers because they had been identified as
having consumed adulterated feed have been released.
