Diversité des productions porcines en France

Consulter le resumé

Jean-Yves Dourmad et al., Innovations agronomiques (FRA), 2018, volume 68, octobre, p. 151-170

Alors que la production porcine française est souvent perçue comme uniforme, il existe une assez grande diversité en termes d'organisation et taille des élevages et d'insertion dans l'exploitation agricole. Les élevages spécialisés représentent 39% des exploitations et 61% du cheptel alors que pour 38% des exploitations l'élevage porcin est associé à la présence de bovins. Au niveau des produits la diversification est surtout assurée en aval par le tri des carcasses et des pièces de découpe, et la transformation. Le porc est en effet valorisé à 75% sous la forme d'une grande diversité de produits transformés qui contraste avec la faible diversité de l'offre en viande fraiche. Depuis quelques années on assiste au développement de différentes démarches valorisant l'origine ou le mode d'élevage. Les leviers de différenciation concernent souvent plusieurs dimensions comme la race des animaux, l'origine géographique des produits, leurs qualités organoleptique ou diététique, l'absence ou la présence de certains composés dans l'alimentation des animaux, le bien-être animal et la production biologique. Cette évolution est favorisée par le renforcement des liens entre les groupements de producteurs et l'aval, y compris jusqu’à la transformation et la distribution.

Diversity of pig production in France

Although French pig production is generally perceived as uniform, a rather large diversity still exists in terms of organization and size of pig units and their integration with the rest of the farm. Specialized pig farms represent 39% of all pig farms and they raise about 61% of all pigs, whereas in 38% of farms the raising of pigs is associated with ruminants. Diversity of pork products is mainly obtained by the sorting of carcasses and cuts, and their processing. Indeed, in France, about 75% of pork is consumed after processing, with a very large diversity of products. This contrasts with the rather low diversity of pork fresh meat. Nevertheless, in the recent years, we may observe the development of strategies of diversification based on the origin or the way of production. The differentiation levers may combine different dimensions among: animal breed, geographic origin, organoleptic and dietetic quality, the absence or the presence of specific compounds in animal feed, animal welfare, and organic production.
This evolution towards increased diversity is promoted by the consolidation of the links between pig producer cooperatives and the downstream of the pork production chain, including processing and distribution sectors.

Avec son potentiel de productions végétales, ses faibles coûts de main d’oeuvre et une tradition de consommation de porc, l’Ukraine pouvait devenir un acteur majeur du commerce international. Mais la propagation de la peste porcine africaine empêche quasiment toute exportation, tandis que le marché intérieur s’est réduit depuis la crise politique et économique de 2014.

Population genetic structure of Listeria monocytogenes strains isolated from the pig and pork meat production chain in France

Consulter le resumé

Benjamin Félix (Anses) et al., Food Micro, 3-6 septembre 2018, Berlin, Allemagne

Listeria monocytogenes is an ubiquitous pathogenic bacterium, transmissible to humans through the consumption of contaminated food. The pork production sector has been hit hard by a series of L. monocytogenes-related food poisoning outbreaks in France. An overview of the diversity of strains circulating at all levels of the pork production chain, from pig farming to finished food products, is needed to identify the contamination routes and improve food safety. Until now, no typing data has been available on strains isolated across the entire pig and pork production chain. 
Here, we analyzed the population genetic structure of 687 L. monocytogenes strains isolated over the last 20 years in virtually all the French départements from three compartments of this production sector: pig farming (PF), the food processing environment (FPE) and finished food products (FFP). The genetic structure was described based on MLST clonal complexes (CCs). The CCs were obtained by mapping the PFGE profiles of the strains. The distribution of CCs was compared firstly between the three compartments and then with CCs obtained from 1106 strains isolated from other food production sectors in France. 
The predominant CCs of pig and pork strains were not equally distributed among the three compartments: the CC37, CC59 and CC77 strains, rarely found in FPE and FFP, were prevalent in PF. The two most prevalent CCs in the FPE and FFP compartments, CC9 and CC121, were rarely or never detected in PF. No CC was exclusively associated with the pork sector. Three CCs (CC5, CC6, CC2) were considered ubiquitous, because they were observed in comparable proportions in all food production sectors. The two most prevalent CCs in all sectors were CC9 and CC121, but their distribution was disparate. CC9 was associated with meat products and food products combining several food categories, whereas CC121 was not associated with any given sector. Based on these results, CC121 is likely able to colonize a larger diversity of food products than CC9. Both CCs being associated with the food production suggests, that certain processing steps, such as slaughtering or stabilization treatments, favor their settlement and the recontamination of the food produced.

Ecology of Salmonella and antimicrobial resistance in a pig slaughterhouse

Consulter le resumé

Arnaud Bridier et al., Food Micro, 3-6 septembre 2018, Berlin, Allemagne et I3S, 24-26 septembre 2018, Saint-Malo, France

Salmonella is a bacterial pathogen responsible for a large number of food associated infections. In order to guarantee food safety, a better understanding of Salmonella ecology and adaptation strategies on the food production chain constitutes a prerequisite. In a One Health perspective, data on Salmonella antibiotic resistance in food environments are also crucial to decipher transmission routes of resistant foodborne pathogens as well as resistance genetic determinants involved, and the role of process and selection pressures underwent in food industries (as cleaning and disinfection) in bacterial adaptation and antimicrobial resistance emergence.
Using a pig slaughterhouse as a model food environment, occurrence of Salmonella was investigated at six different areas along the slaughter chain and through 4 sampling campaign, each time before and after cleaning and disinfection procedures (a total of 48 surface samples). Characterization of isolated Salmonella strains using serotyping and pulsotyping enabled to identify and trace persistent strains in the slaughterhouse. Minimal inhibiting concentrations (MIC) were also determined for various relevant antibiotics and for biocides used in the slaughterhouse. In addition, associated indigenous bacterial communities were characterized using 16S rRNA amplicon sequencing. 
Results revealed the presence of Salmonella at all sampling area. Five serotypes were identified: S.4,5,12:i:- (50%), Rissen (16%), Typhimurium (16%), Infantis (10%) and Derby (8%). Strains were found at different dates and potentially at the same sampling area suggesting they persist in the slaughterhouse despite of the cleaning and disinfection procedures. Approximately 70% of isolated Salmonella strains exhibit resistance to ampicillin and sulfamethoxazole, 80% to tetracycline and 10% to chloramphenicol. There was no evolution of CMI comparing strains before and after cleaning and disinfection procedures concerning both biocides and antibiotics. Bacterial diversity analyses showed that populations in slaughterhouse were highly dominated by &a1;-proteobacteria and especially by the Moraxellaceae family (genus Psychrobacter, Moraxella, Enhydrobacter and Acinetobacter) at the different sampling areas. Population compositions were overall stable in time at a given sampling area suggesting that the surface populations are resident populations within the slaughterhouse, rather than populations introduced each week by the new swine bands. Cleaning and disinfection procedures tend to reduce bacterial diversity by eliminating the minority species but did not greatly impact the composition of bacterial communities with regards to the dominant species.
Together, such data participate to the construction of a comprehensive view of Salmonella ecology in food environments integrating associated resident microbial flora and the distribution of antimicrobial resistance in relation to processing conditions.

A pan-European computed tomography procedure for measuring the new EU lean meat content of pigs

Consulter le resumé

Gérard Daumas et Mathieu Monziols, 69th Annual meeting of the european federation of animal science (EAAP), Dubrovnik, Croatie, 27-31 août 2018, poster

A new EU regulation on carcass classification applies from July 2018. The new reference to calibrate the pig classification methods is a lean meat percentage based on total dissection (LMPtd). Manual dissection can be replaced by an unbiased computed tomography (CT) procedure. If the national pig population to be sampled has the same characteristics as the population for which a CT procedure has been previously corrected, no additional dissection is required. In most of the national applications for authorisation of classification methods the population characteristics are managed via a stratification on a fat depth, mimicking the LMP variation.
The aim of this paper is to propose a pan-European CT procedure to calibrate the pig classification methods without any additional manual dissection. A sample of 29 half-carcasses was CT scanned with 3 mm slice thickness and then fully dissected according to the EU regulation. The CT muscle volume was calculated by thresholding in the Hounsfield range 0-120. It was converted into muscle weight by applying a density of 1.04. The weight was divided by the carcass weight to obtain the lean meat percentage from CT (LMPct), in the same way as done for the LMPtd. LMPtd was regressed on LMPct. Only the slope was significant and was estimated at 0.965 (s.e.=0.002). The RMSE was 0.81. The plot of residuals against fitted values showed no pattern and no heterogeneity of variances. The main source of measurement error is the thresholding of the rind. As the thickness of the rind is very thin (2-3 mm), most of the voxels including rind are mixed voxels, either with air or with fat. Their Hounsfield values are therefore less than 0 and these voxels are classified in non-muscle. Only a few rind voxels have a Hounsfield value in the range [0-120 HU] and are thus misclassified in muscle. This is taken into account by the slope value which is slightly less than 1. The LMPtd range in the sample (53-68) covers the S+E classes (>= 55) which represent more than 90% of the EU pigs. It covers too more than 80% of all the national populations, excepted Italy. This robust CT procedure can therefore be applied in 27 Member States, by using a pan-European multiplicative factor of 0.965, without any additional national dissection.

G Dervilly-Pinel (ONIRIS) et al., 69h Annual meeting of the european federation of animal science (EAAP), Dubrovnik, Croatie, 27-31 août 2018

Even if there is no clear evidence that organic food products are healthier than conventional ones, the presumed absence of chemical contaminants is reported as main driver for organic consumers.. To provide occurrence data in a context of chronic exposure, samples of liver and meat (psoas major muscle) were collected in 2014 in six French slaughterhouses representing 70 pig farms, including 30 organic, 12 Label Rouge and 28 conventional. Each sample corresponded to a pool of tissues of three carcasses. Environmental contaminants (17 polychlorinated dibenzodioxins/ dibenzofurans (Dioxins), 18 polychlorinated biphenyls (PCBs), 3 hexabromocyclododecane (HBCD) isomers, 6 mycotoxins, 6 trace metal elements) and residues from production inputs (75 antimicrobials and 121 pesticides) were investigated using the most sensitive methods. Contamination levels were measured below regulatory limits in all the samples. However, some differences were observed between types of farming. Dioxins, PCBs and HBCD concentrations were thus observed as significantly higher in organic meat samples. Cu, Zn and As were measured at slightly higher levels in organic meat without differences between organic and Label Rouge. Liver samples from conventional and Label Rouge farms exhibited higher contents in Zn and Cd than the organic ones. Ochratoxin A was the only mycotoxin quantified in 25 samples (36%) and detected in another 22 samples (31%) of the livers analysed, without significant differences between farming systems. A correlation could be observed between mycotoxins concentrations in meat and liver. All meat samples exhibited pesticides levels below the detection limits, whereas only 3 conventional or organic samples (overall: 3.5%) displayed residual concentrations of authorized veterinary antimicrobials, but with concentrations far below the regulatory limits.

Marie-José Mercat et al., 69th Annual Meeting of the European Federation of Animal Science (EAAP), Dubrovnik, Croatie, le 27-31 août 2018, visuels d'intervention

In order to further allow implementation of breeding programs in local pig breeds, with selection objectives defined for each local breed, we aimed at developing a standardised recording of carcass and meat quality traits. These data have to be connected with herdbooks to estimate genetic parameters of the traits (heritabilities and genetic correlations) which are necessary to define breeding objectives. Today the situation is very different from one local breed to another. No or very few phenotypes are recorded in some of them, while breeding programs already exist for a few breeds. To promote phenotyping, a dedicated database and a website were developed in the frame of the TREASURE project. First, the required variables have been collected for six local breeds: Basque (FR), Bísaro (PT), Crna slavonska (HR), Gascon (FR), Krškopoljski (SI) and Schwäbisch-Hällisches (DE). In total 74 variables have been identified dealing with animal herdbook information (10), rearing and growth (22), carcass (22) and meat quality (20) attributes. The database is compatible with the various identifiers used in the different countries: animal IDs, breed, farm… codifications. Major attention has been paid to the description of measurement methods of traits. Thus, each carcass and meat quality phenotype is associated to a method description representing 35 additional variables. The website can be easily translated into several languages. The website and database are currently on test until the end of the TREASURE project. All the breeds studied in TREASURE are free to use these tools. The database can be duplicated so that each partner can host its own data. Funded by European Union H2020 RIA program (grant agreement no. 634476).

Retrospective by sex of the new EU lean meat content of pig carcasses

Consulter le resumé

Gérard Daumas, 69th Annual meeting of the european federation of animal science (EAAP), Dubrovnik, Croatie, 27-31 août 2018, poster

A new EU regulation on carcass classification applies from July 2018. This regulation changes the definition of the reference lean meat percentage (LMP) which becomes the LMP in the carcass (from total dissection). Nevertheless, each Member State can choose when he will update its grading methods. The aim of this work is to simulate this change on the last 5 years in France for each sex.
Conversely to most of European countries sex is registered online in France during pig classification. Statistics per sex are regularly published by the regional classification organisations.
The production of entire males started in France in 2013 (13% of the males), increased quickly and is now stable (27% of the males in 2017), around 2.5 million a year. More than 95% of entire males are classified with the classification method CSB Image-Meater® (IM) approved by the EU in 2013. The present LMP prediction equation contains two fat depths (G3 and G4) and two muscle depths (M3 and M4).
A sample of 180 pigs was uniformly stratified on sex: 60 entire males, 60 females and 60 castrated males. All cuts were CT scanned allowing to calculate the LMP. Prediction equation was calculated by a general linear model including the 4 depths as well as the interactions with sex. The stepwise procedure by using BIC selected a model with 1 fat depth (G3) and 2 muscle depths (M3 and M4), G3 and M3 coefficients depending on sex. The RMSE was 2.15. Removal of M4 only decreased the RMSE of 0.01. The fat coefficient of entire males was more than twice that of females, while that of castrates was in the middle. Differences on M3 coefficient had lower impact on LMP.
The equation was applied on the annual classification averages from 2013 to 2017. In 4 years LMP increased, but differently according to sex: +0.11 for entire males, +0.25 for females and +0.34 for castrated males. In the same period the difference between entire and castrated males decreased from 4.02 to 3.79, while the difference between entire males and females decreased from 1.37 to 1.24.
When the Image-Meater method will be updated, it seems worthwhile to consider separate slopes for entire males, females and castrated males.

Computed tomography for comparing the lean meat content of different genotypes of entire male pigs

Consulter le resumé

Gérard Dumas et al., 64rd International Congress of Meat Science and Technology (ICOMST), 12–17 août 2018, Melbourne, Australie, poster

From July 2018 the EU reference for pig grading is the lean meat percentage (LMP) based on total dissection of a half-carcass. Dissection can be replaced by an unbiased computed tomography (CT) procedure. Daumas et Monziols (2018) developed a pan-European CT procedure for determining this LMP. The hypothesis is such a procedure could be applied on very lean carcasses, issued from entire males of purebred used as terminal sires in production. The aim of this paper is to test this CT procedure to assess the LMP differences between several lean genetic groups and the three halothane genotypes.

Early prediction of Semimembranosus ultimate pH with Raman spectroscopy of pig carcasses

Consulter le resumé

Antoine Vautier et al., 64th International Congress of Meat Science and Technology (ICOMST), 12–17 août 2018, Melbourne, Australie

The ultimate pH (pH24) is a crucial meat quality parameter in the pork meat industry, but its measurement time is still an issue for slaughterhouses due to difficulties to keep up the required 18h post mortem (pm) time minimum. Raman spectroscopy showed the potential to predict pH24 of Semimembranosus when performed during chilling at 60 to 120 minutes pm [1] and on the slaughter line at 30 to 60 minutes pm [2]. The objective of the study is to validate the accuracy of the 671 nm emission Raman device developed by Schmidt et al. [3] to predict pork meat quality on a French pork population at the end of the slaughter line (30 min pm). The ability to predict the “jambon cuit supérieur” cooking yield and slicing defects has also been tested.
