Commercialization in the meat-processing industry has emerged as one of the major agrobusiness challenges due to the large volume of wastewater produced during slaughtering and cleaning of slaughtering facilities. Slaughterhouse wastewater (SWW) contains proteins, fats, high organic contents, microbes, and other emerging pollutants (pharmaceutical and veterinary residues). It is important to first characterize the wastewater so that adequate treatment techniques can be employed so that discharge of this wastewater does not negatively impact the environment. Conventional characterization bulk parameters of slaughterhouse wastewater include pH, color, turbidity, biochemical oxygen demand (BOD), chemical oxygen demand (COD), total organic carbon (TOC), total suspended solids (TSS), total nitrogen (TN), total phosphorus (TP), and coliform counts. Characterization studies conducted have revealed the effects of the pollutants on microbial activity of SWW through identification of toxicity of antibiotic-resistant strains of bacteria. Due to the high-strength characteristics and complex recalcitrant pollutants, treatment techniques through combined processes such as anaerobic digestion coupled with advanced oxidation process were found to be more effective than stand-alone methods. Hence, there is need to explore and evaluate innovative treatments and techniques to provide a comprehensive summary of processes that can reduce the toxicity of slaughterhouse wastewater to the environment. This work presents a review of recent studies on the characterization of SWW, innovative treatments and technologies, and critical assessment for future research.

“…Bacteria can respond to different types of selective pressures, including antimicrobials by the acquisition of new phenotypes via phage mediated transduction. Understanding the mechanisms behind this phenomenon occurring during food process and developing strategies to avoid it will contribute to mitigate the transfer of food-borne pathogens during activities such as slicing, washing, or cleaning and the spread on ARGs via bacteriophages which are more resistant to different treatment processes than pathogenic bacteria themselves (Rahmani et al 2020).…”

Antibiotic resistance genes (ARGs) are a global health concern. Antibiotic resistance occurs naturally, but misuse of antibiotics in humans and animals is accelerating the process of antibiotic resistance emergency, which has been aggravated by exposure to molecules of antibiotics present in clinical and agricultural settings and the engagement of many countries in water reuse especially in Middle East and North Africa region. Bacteriophages have the potential to be significant actors in ARGs transmission through the transduction process. These viruses have been detected along with ARGs in non impacted habitats and in anthropogenic impacted environments like wastewater, reclaimed water and manure amended soil as well as minimally processed food and ready to eat vegetables. The ubiquity of bacteriophages and their persistence in the environment raises concern about their involvement in ARGs transmission among different biomes and the generation of pathogenicresistant bacteria that pose a great threat to human health. The aim of this review is to give an overview of the potential role of bacteriophages in the dissemination and the transfer of ARGs to pathogens in food production and processing and the consequent contribution to antibiotic resistance transmission through faecal oral route carrying ARGs to our dishes.

“…The presence of resistant gram-positive bacteria in aquatic sites is of concern, as some are signs of fecal contamination, such as Enterococcus. Others are pathogenic to humans, such as Staphylococcus (Karkman et al, 2018), in which the acquisition of resistance genes makes it difficult to find effective antimicrobials against infections (Rahmani et al, 2020). Other gram-positive bacteria considered important are Streptococcus spp., which are responsible for being pathogenic and for developing severe infections in humans (Zhang et al, 2018), and Bacillus spp.…”

The Meia Ponte River – Goiás/Brazil, is responsible for benefiting about 2 million people in Goiás State. However, the increase in pollution with the disposal of sewage, chemicals and drug remains have contributed to the increase in bacterial resistance and the exchange of resistance genes. The objective of this study was to isolate, identify and analyze the resistance profile of gram-positive bacteria present in raw water and sediment of the Meia Ponte River – Goiás. The samples were collected from four sampling points and two collections were carried out, one in the dry season and the other in the rainy season. The isolated bacteria were identificated, then the antibiogram was performed. A total of 75 strains were isolated, 72.0% (54/75) of Streptococcus spp., 12.0% (9/75) of Staphylococcus spp., 9.3% (7/75) of Bacillus spp. and 6.7% (5/75) of Enterococcus spp. Furthermore, 52.0% (39/75) of the isolated strains were from raw water and 48.0% (36/75) were isolated from the sediment. Among the samples, strains of Staphylococcus spp. and Bacillus spp. showed greater resistance to antimicrobials, on the other hand, Enterococcus spp. showed less resistance. Some strains of Bacillus spp. and Streptococcus spp. presented multidrug resistant, Staphylococcus spp. showed multidrug resistant and some pan-drug resistant. In the correlation of Spearman Staphylococcus spp. and Streptococcus spp. isolated, were the ones that presented the most significant correlations (p < 0.05). Thus, the study shows the importance of ascertaining the resistance profile of this group of bacteria that aquatic environment.
