“…The complete resistance of goat milk Lactobacillus isolates towards glycopeptides (teicoplanin, vancomycin) is in line to other reports (Nawaz et al, 2011). Intrinsic resistance towards vancomycin might be due to the presence of D-Ala-D-lactate in the cell wall peptidoglycan, rather than the D-ala-Dala dipeptide moiety.…”

“…Lactic acid bacteria has GRAS status (generally recognized as safe); however, the presence and expression of antibiotic resistance genes in LAB have been reported (Ouoba et al, 2008;Nawaz et al, 2011). Antibiotic resistance genes of lactic acid bacteria can potentially be transferred to the commensal flora of human and animals and to opportunistic and/or pathogenic bacteria.…”

There is a significant range of bacterial inoculants for forage ensiling, but there is still a need for formulations to improve the safety of feed. The objective of the study was to evaluate the usefulness of three lactobacilli strains in alfalfa (Medicago sativa L.) The following bacterial inoculants were used: Lactocacillus plantarum K KKP 593p (LPK), L. plantarum C KKP 788p (LPC), L. buchneri KKP 907p (LB), and mix of all three strains (LPK+LPC+LB). The application of bacterial inoculants in alfalfa ensiling resulted in a reduction of the total number of molds, Clostridium perfringens and Listeria sp. (up to 5, 7, and 5 times respectively for LB inoculant in comparison to untreated silage). Total inhibition of Salmonella sp. and Escherichia coli growth was achieved in silages treated with all inoculants except for LPC. Aerobic stability in the control silage was the lowest (77 h) and doubled under the influence of bacterial inoculants. The most stable according to aerobic stability was silage treated with LB inoculant (175 h), where the highest concentrations of acetic acid (4.8 g kg -1 ), propionic acid (0.7 g kg -1 ) and 1,2-propanediol (526 mg kg -1 ) were reported. The study discussed that it is important to evaluate not only the effect of bacterial inoculants on physicochemical and microbiological silage properties, as the presence and expression of antibiotic resistance genes in lactic acid bacteria have been reported. The results of antimicrobial susceptibility testing of the strains showed that almost all minimum inhibitory concentrations values for eight antibiotics were equal to or below the corresponding breakpoints proposed by the European Food Safety Authority, Additives and Products or Substances used in Animal Feed Panel.

“…Intrinsic resistance could be shown mainly for aminoglycosides, quinolones, and glycopeptides (Hummel et al, 2007;Klein, 2011). Moreover, the transfer of antibiotic resistance within LAB isolates from food has been recently studied (Nawaz et al, 2011;Toomey et al, 2010). Presence of genes coding for antibiotic resistances, such as tet…”

EFSA is requested to assess the safety of a broad range of biological agents in the context of notifications for market authorisation as sources of food and feed additives, enzymes and plant protection products. The qualified presumption of safety (QPS) assessment was developed to provide a harmonised generic pre-assessment to support safety risk assessments performed by EFSA's scientific Panels. The safety of unambiguously defined biological agents (at the highest taxonomic unit appropriate for the purpose for which an application is intended), and the completeness of the body of knowledge are assessed. Identified safety concerns for a taxonomic unit are, where possible and reasonable in number, reflected as 'qualifications' in connection with a recommendation for a QPS status. The list of QPS recommended biological agents is reviewed and updated periodically. Therefore, the only valid list is the one in the most recently published scientific opinion. The 2013 update reviews previously assessed microorganisms including bacteria, yeasts, filamentous fungi, oomycetes and viruses used for plant protection purposes. All taxonomic units previously recommended for the QPS list had their status reconfirmed. The new notifications since the last QPS update were reviewed. Gluconobacter oxydans and Alphaflexiviridae were assessed for the first time and were recommended for the QPS list. The information of the previous opinion was updated for the taxonomic units on the QPS list. Qualifications for the taxonomic units included in the QPS recommended list were reviewed and confirmed. Filamentous fungi and enterococci were not recommended for the QPS list following updating and reviewing of current scientific knowledge. SUMMARYThe European Food Safety Authority (EFSA) asked the Panel on Biological Hazards (BIOHAZ) to deliver a Scientific Opinion on the maintenance of the list of QPS biological agents intentionally added to food or feed (2013 update). The question included four specific tasks in the terms of reference (ToR).The first required a preparation of an update of the list of biological agents for intentional use in feed and/or food, or as sources of food and feed additives or enzymes and as plant protection products for safety assessment as notified to EFSA Units and/or Scientific Panels such as Pesticides, the Panels on Additives and Products or Substances used in Animal Feed (FEEDAP) and Genetically Modified Organisms (GMO). The list was updated with the notifications received where applicable by EFSA Panels and Units since the last review.The second ToR was concerned with an annual review of the list of biological agents recommended for the QPS list. Where appropriate new taxonomic units should be assessed for their suitability for an inclusion in the QPS list, and taxonomic units previously assessed should be reviewed where new information has become available. The information provided in the previous opinion should be updated where appropriate. The BIOHAZ Panel confirmed all taxonomic units previously re...
