Vk. Tuovinen et al., PARTIAL CONDEMNATIONS OF SWINE CARCASSES - A DESCRIPTIVE STUDY OF MEAT INSPECTION FINDINGS AT SOUTHWESTERN FINLAND COOPERATIVE SLAUGHTERHOUSE, Preventive veterinary medicine, 19(2), 1994, pp. 69-84
Meat inspection findings at Finland's largest abattoir, Southwestern F
inland's Cooperative Slaughterhouse (LSO), are described with special
reference to partial carcass condemnations (PCC). Of the 714 458 pigs
slaughtered in 1991, 0.64% were totally and 3.62% partially condemned.
Liver, and other organ condemnation percentages were 3.22% and 1.50%,
respectively. Partial condemnations were mostly due to arthritis (50.
0%) and abscesses (35.5%). Monthly indices created by time series anal
ysis suggested the highest risk for PCC in October and May. The lowest
indices were for December and August. The highest risk for abscesses
was in spring, and for joint infections in October.There were large va
riations in PCC percentage between the three slaughter plants of LSO a
s well as between the nine supply areas. The PCC percentage of the sam
pled all in-all out finishing units (N = 433 in 1990, N = 442 in 1991
) varied from 0 to 10%. Farm size had a statistically significant but,
practically negligible association with PCC. A strong association bet
ween slaughter weight (analyzed on an individual level) and PCC percen
tage was found. The risk of PCC increased as the slaughter weight decr
eased. The average amount of meat wasted per partial condemnation was
4.11 kg in 1991. The direct costs of PCC were 27.12 FMK kg-1 condemned
meat (1 FMK or 1 Finnish mark is equal to about US$0.2), 111.43 FMK p
er condemnation, 4.04 FMK per slaughtered pig, and totalled 2.88 milli
on FMK. The average weight of totally condemned carcasses was 50.3 kg.
Direct annual costs of whole carcass condemnations were estimated to
be 3.86 million FMK in 1991. Price deductions due to liver condemnatio
ns were 0.17 million FMK, 7.43 FMK per rejection. Other organ condemna
tion costs were 0.37 million FMK, 34.21 FMK per rejection. An estimati
on of the direct costs of all condemnations was 10.20 FMK per slaughte
red pig, and totalled 7.28 million FMK. All the other condemnations ex
cept liver condemnations were positively correlated with PCC. Mortalit
y in the finishing unit was also positively correlated with PCC.
