Alguns perigos que podem ameaçar a saúde dos consumidores de carne de porco e de produtos processados estão relacionados com a saúde animal ou com a manipulação da matéria-prima desde o abate dos animais, a transformação e até ao consumo. Entre os perigos químicos consideram-se as substâncias com efeitos anabólicos, os resíduos de substâncias medicamentosas e os contaminantes químicos, alguns com origem na produção animal ou produzidos durante o processamento. No que se refere aos perigos biológicos, podem encontrar-se alguns parasitas como Toxoplasma gondii, Trichinella spiralis e Taenia solium e também bactérias como Salmonella spp, Campylobacter spp., Yersinia enterocolitica, Listeria monocytogenes. As características físico-químicas da carne fresca facilitam o crescimento de diversos microrganismos, para além dos mencionados anteriormente, o que a torna altamente perecível. Os diferentes processos de transformação desta matéria-prima, não só permitem obter diferentes alimentos para o consumidor como constituem formas de aumentar a sua vida útil. Entre os processos de transformação incluem-se a secagem, a fermentação e a cura. Em Portugal há uma grande variedade de produtos cárneos tais como Chouriço, Paio, Presunto, Salsichão e Catalão, muitos dos quais são fabricados segundo as técnicas tradicionais das diferentes regiões de onde são originários. Alguns destes produtos têm sido estudados na Universidade de Évora. Apresentaremos alguns resultados que mostram o efeito favorável de vários processos de transformação no controlo de alguns dos perigos biológicos mencionados.

From December 1993 to March 1994, a total of 93 wild boar and 30 deer meat samples were purchased from 13 retail shops and examined for the presence of species of Erysipelothrix, Yersinia, Listeria, Salmonella and Campylobacter. Erysipelothrix spp. were isolated from 41 wild boar and 15 deer samples. These isolates were identified as 13 serotypes. Serotypes 6 and 2 were the most predominant. Of 17 isolates examined, 14 isolates were highly virulent for mice. The bacteria of the same serotype were isolated repeatedly from the samples purchased in 4 of the shops. Yersinia enterocolitica was isolated from 36 wild boar and 10 deer samples; however, all isolates of Y. enterocolitica did not have pathogenic properties. Listeria monocytogenes was isolated from 5 wild boar samples. The isolates were identified as serotype 1/2c and 4b. Salmonella spp. were isolated from 2 wild boar samples; one isolate was identified as S. typhimurium and the other was untypable. Campylobacter spp. were not detected.

La prévalence de Listeria, Salmonella, Campylobacter, Yersinia et Cryptosporidium dans du lait en vrac, les matières fécales des vaches laitières et des effluents à lait des fermes laitières de l'île de la Trinité, a été evaluée. Des 177 échantillons de lait en vrac testés, 3 (1,7 %), 3 (1,7 %) et 2 (1,2 %) étaient positifs respectivement pour Listeria monocytogenes, Salmonella spp. et Yersinia enterocolitica mais négatifs pour Campylobacter spp. et Cryptosporidium spp. Des 333 échantillons fécaux testés, L. monocytogenes, Campylobacter spp. et Cryptosporidium spp. étaient présents dans respectivement 11 (3,3 %), 19 (5,7 %) et 7 (2,1 %) des cas. Ces taux étaient significativement (P < 0,05; chi2) plus élevés, que le taux de détection (0 %) pour Yersinia spp. Salmonella spp. a été detectée dans 3 (0,9 %) échantillons fécaux. Des 168 échantillons prélevés des effluents à lait, Campylobacter spp. était présent dans 7 (4,2 %) échantillons alors que Salmonella spp. l'était dans seulement 1 (0,6 %) échantillon. Aucun échantillon n'était positif pour Yersinia spp. et Listeria spp. (différence significative, P<= 0,05; chi2). En conclusion, les cinq espèces entero-pathogènes testées étaient présentes dans les fermes laitières de l'île de la Trinité.

A study of imported unprepared whole lettuces sampled from supermarkets, greengrocers, shops, and market stalls found that all were of acceptable microbiological quality. Twenty-seven out of 151 (18%) imported lettuce samples had Enterobacteriaceae levels of 104 CFU/g or more. However, these bacteria that constitute part of the natural microflora of unprepared vegetables may also be derived from the soil and/or by poor handling. The pathogens, Salmonella spp., Shigella spp., Campylobacter spp., Escherichia coli O157:H7, Vibrio cholerae, Listeria monocytogenes, and also Escherichia coli, an indicator of fecal contamination, were not detected in any imported lettuces, indicating that hygiene, harvesting, and production practices were good. Imported lettuces with Enterobacteriaceae levels of 104 CFU/g or more varied with type of retail premises and the temperature at which the lettuces were displayed. Samples from greengrocers, shops, and market stalls were more likely to contain Enterobacteriaceae at levels in excess of 104 CFU/g than those from supermarkets.

Campylobacter Spp

Foreword Abortion takes a heavy toll on the sheep industry, not only economically, but in emotional terms too. Enzootic abortion in ewes is consistently the most frequent diagnosis followed in descending order by infection with Toxoplasma gondii, Campylobacter spp., Salmonella spp. and Listeria spp. Causes of abortion also lead to increased barren rates, and the birth of weak lambs, so the impact of these pathogens is greater than just abortion. Fortunately there are vaccines for the two most common causes of abortion, providing farmers and the veterinary surgeons advising them with effective and sustainable tools in the control of enzootic abortion and toxoplasmosis. The uptake of these vaccines, however, remains lower than might reasonably be expected. In this roundtable discussion the barriers to the implementation of the extant measures of abortion control were discussed and suggestions made as to how abortion can better be prevented.

In 1995 and 1996 a nine-month study was carried out in 11 pig abattoirs located in the Molise region (Italy) to evaluate the degree of contamination of- the slaughterhouse environment, work surfaces, equipment, and personnel by Salmonella spp., Listeria spp., and Yersinia spp. A total of 219 samples were taken over three replications including slaughtering floor and wall, hooks, work-tables, chopping blocks, knives, cleavers, dehairing devices, hands of personnel, clothing, hand-wash basins, and cold room handles, floor, wall, and hooks. Overall, six abattoirs (54.5%) had one or more positive sites, while only 14 of the 219 sites (6.4%) tested were positive for any of considered microorganisms. Salmonella spp. were isolated from 1 of 9 cleavers (11.1 %), 1 of 16 worktables (6.25%), and 1 of 18 slaughtering floors (5.6%). Yersinia enterocolitica was found on 3 slaughtering floors (16.7%) and on 2 worktables (12.5%). Yersinia kristensenii was detected on 2 slaughtering floor swabs (11.1 %). Listeria monocytogenes was isolated from 2 of 20 cold room floor swabs (13.3%) and from 1 of 14 hand-wash basins (7.1%). Other species of Listeria were detected on slaughtering wall and floor swabs and on chopping blocks. Our study indicates that slaughtering floors, cold room floors, and worktables are important sites in abattoirs that may possibly harbor pathogens like Salmonella spp., Yersinia enterocolitica, and Listeria monocytogenes, and that cleaning and sanitizing of the slaughterhouse environment and equipment need a greater emphasis.
