The aim of the study was to review the results of scientific research on the effect of herbs and phytogenic feed additives used in poultry nutrition on animal welfare, breeding conditions, and the quality of meat. The article explains the importance of feed additives used in poultry nutrition. It discusses the role of herbs and phytogenic feed additives in nutrition in the context of the increasing demand for and consumption of poultry meat. The article also analyzes the influence of herbs and phytogenic feed additives on animal welfare, rearing conditions, and meat quality. The results of research on the effect of herbs and phytogenic feed additives used in poultry nutrition are not unequivocal. In view of the high demand for poultry meat, there is need for continued research on the optimal composition of herbal mixtures in nutrition to obtain good breeding conditions and high quality meat.

Fourier transform infrared spectroscopy (FT-IR) and multispectral imaging (MSI) were evaluated for the prediction of the microbiological quality of poultry meat via regression and classification models. Chicken thigh fillets (n = 402) were subjected to spoilage experiments at eight isothermal and two dynamic temperature profiles. Samples were analyzed microbiologically (total viable counts (TVCs) and Pseudomonas spp.), while simultaneously MSI and FT-IR spectra were acquired. The organoleptic quality of the samples was also evaluated by a sensory panel, establishing a TVC spoilage threshold at 6.99 log CFU/cm2. Partial least squares regression (PLS-R) models were employed in the assessment of TVCs and Pseudomonas spp. counts on chicken’s surface. Furthermore, classification models (linear discriminant analysis (LDA), quadratic discriminant analysis (QDA), support vector machines (SVMs), and quadratic support vector machines (QSVMs)) were developed to discriminate the samples in two quality classes (fresh vs. spoiled). PLS-R models developed on MSI data predicted TVCs and Pseudomonas spp. counts satisfactorily, with root mean squared error (RMSE) values of 0.987 and 1.215 log CFU/cm2, respectively. SVM model coupled to MSI data exhibited the highest performance with an overall accuracy of 94.4%, while in the case of FT-IR, improved classification was obtained with the QDA model (overall accuracy 71.4%). These results confirm the efficacy of MSI and FT-IR as rapid methods to assess the quality in poultry products.

ABSTRACT This study focused on assessing the microbiology of conveyor belts surfaces, cleaned or not with pressurized water, and verification of the influence of this process on the microbiological quality of poultry meat. A reduction on mesophilic, psychrotrophic and Enterobacteriaceae counts (P<0.05) on dry conveyor belts compared to wet ones was observed. For the chicken leg (consisting of drumstick and thigh) samples, no statistically significant differences were detected on counts of indicators of microorganisms on poultry legs (composed by drumstick and thigh). For poultry meat conducted on wet or dry conveyor belts, 99% and 86%, were positive for Listeria spp, respectively. Only one sample of chicken leg was positive for presence of L. monocytogenes. These results demonstrate that there is no need to use water for cleaning conveyor belts during processing, which allows a reduction on the use of potable water in poultry slaughterhouses without jeopardizing food safety and public health.

Mechanically Separated Meat

Mechanically separated meat (MSM) is obtained from bones or fragments with naturally adherent soft tissue by mechanical separation of soft tissue residues from bones remaining after cutting and punching poultry, pork and beef carcasses. Mechanically separated meat is a raw material commonly used in processing in Poland and other countries. The dominant species in the production of mechanically separated meat in Europe is poultry, mainly because of the increase in the consumption of boneless meat and its products. Mechanically separated meat is characterized by poorer technological and physicochemical properties and lower durability compared to poultry meat cut by hand. The high microbiological contamination of raw material limits its further use. The microbiological quality of mechanically separated meat has a significant impact on the microbiological stability and health safety of products manufactured from it. In industrial practice, mechanically separated meat is preserved by freezing or curing. In view of problems with the microbiological quality of mechanically separated meat, it seems advisable to search for new methods of preserving MSM and to improve the existing ones

A total of 40 eviscerated and refrigerated chicken carcasses were collected from five retail outlets (three supermarkets and two poulterers' shops) in León (Spain). The level of microorganisms on chicken carcasses was assessed using the excised breast-skin technique. Mean counts (log10 CFU/g) of psychrotrophs, pseudomonads, fluorescent pseudomonads, enterococci, Micrococcaceae, Staphylococcus aureus, and yeasts and molds were 4.84, 4.11, 3.32, 2.72, 3.80, 3.67, and 2.99, respectively. A significant correlation coefficient was found between pseudomonads and fluorescent pseudomonad counts (r = 0.827; P &lt; 0.001) and between Micrococcaceae and S. aureus counts (r = 0.915; P &lt; 0.001). Levels of psychrotrophs, pseudomonads, fluorescent pseudomonads, and yeasts and molds were significantly (P &lt; 0.05) higher in supermarkets than in poulterers' shops, possibly due to the longer period of time the carcasses spent in the supermarkets (between 1 and 2 days, as opposed to only 4 to 16 h in the case of poulterers' shops). Carcasses from poulterers' shops showed higher (P &lt; 0.05) counts of enterococci, Micrococcaceae, and S. aureus, which suggests higher storage temperatures in these outlets. Only S. aureus counts (especially those from poulterers' shops) exceeded the established values in the microbiological criteria for poultry meat consulted.
