Today’s News

Distribution of the erm (B) gene, tetracycline resistance genes, and Tn1545-like
transposons in macrolide- and lincosamide-resistant enterococci from pigs and
humans.

The distribution of the erm (B) and the tetracycline resistance genes tet(K), tet(L), tet(M), tet(O), and tet(S) was
investigated among macrolide- and lincosamide-resistant enterococci originating from humans, pigs, and pork
carcasses. The presence of transposons of the Tn916/Tn1545 family was also traced in these isolates.
Furthermore, the porcine strains were tested for the presence of glycopeptide resistance genes vanA and vanB.
The erm(B) gene was found in 85% of the porcine and in all human isolates. Ninety-eight percent of the porcine
and 89% of the human erm(B)-positive enterococci carried the tet(M) gene. Seventy-seven percent and 70%,
respectively, of these strains harbored a Tn1545-like element. Tet(L) was observed in 68% of the porcine and in
65% of the human enterococci. The other tetracycline resistance genes were very rare and the glycopeptide
resistance genes vanA and vanB were not detected among the porcine isolates. The similar frequencies of
resistance genes and the highly mobile Tn1545-like transposon among porcine and human enterococci might
indicate exchange of resistant strains or their resistance genes between humans and pigs or the existence of a
common reservoir.
Disease risks from foods, England and Wales, 1996-2000.

Data from population-based studies and national surveillance systems were collated and analyzed to estimate the
impact of disease and risks associated with eating different foods in England and Wales. From 1996 to 2000, an
estimated 1,724,315 cases of indigenous foodborne disease per year resulted in 21,997 hospitalizations and 687
deaths. The greatest impact on the healthcare sector arose from foodborne Campylobacter infection (160,788
primary care visits and 15,918 hospitalizations), while salmonellosis caused the most deaths (209). The most
important cause of indigenous foodborne disease was contaminated chicken (398,420 cases, risk [cases/million
servings] = 111; case-fatality rate [deaths/100,000 cases] = 35, deaths = 141). Red meat (beef, lamb, and pork)
contributed heavily to deaths, despite lower levels of risk (287,485 cases, risk = 24, case-fatality rate = 57, deaths
= 164). Reducing the impact of indigenous foodborne disease is mainly dependent on controlling the
contamination of chicken.
Preslaughter handling effects on pork quality and glycolytic potential in two muscles
differing in fiber type composition.

The objective of the present experiment was to investigate the effects of transportation, lairage, and preslaughter
stressor treatment on glycolytic potential and pork quality of the glycolytic longissimus and the oxidative
supraspinatus (SSP) or serratus ventralis (SV) muscles. In a 2 x 2 x 2 factorial design, 384 pigs were assigned
randomly either to short (50 min) and smooth or long (3 h) and rough transport, long (3 h) or short (< 45 min)
lairage, and minimal or high preslaughter stress. Muscle samples were taken from the LM at 135 min and from
the SSP at 160 min postmortem for determination of the glycolytic potential and rate of glycolysis. At 23 h
postmortem, pork quality was assessed in the LM and the SV. Effects of transport and lairage conditions were
similar in both muscle types. Long transport increased (P < 0.01) the glycolytic potential and muscle lactate
concentrations compared with short transport. Both long transportation and short lairage decreased (P < 0.01)
redness (a* values) and yellowness (b*
values) of the LM and SV. In combination with short lairage, long transport decreased (P < 0.05) pork lightness
(lower L* values), and electrical conductivity was increased (P < 0.05) after long transport. Several interactions
between stress level and muscle type (P < 0.001) were observed. High preslaughter stress decreased (P < 0.001)
muscle glycogen in both the LM and SSP, but this decrease was greater in the LM. Lactate concentrations were
increased (P < 0.001) only in the LM by high preslaughter stress. Increases in ultimate pH (P < 0.001) and
decreases in a* values (P < 0.01) were greatest in the SV, whereas increases in electrical conductivity (P <
0.001) were greatest in the LM. The lack of interactions among transportation, lairage, and muscle type was
attributed to the relatively minor differences in stress among treatments. It was concluded that, in glycolytic
muscle types such as the LM, the high physical and psychological stress levels associated with stress in the
immediate preslaughter period have a greater effect on the water-holding capacity of the meat and may promote
PSE development. Conversely, oxidative muscle types tend to have higher ultimate pH values and produce DFD
pork in response to intense physical activity and/or high psychological stress levels preslaughter.
