Food and feed spoiling and mycotoxicogenic moulds cause great economic losses worldwide. The reduction of mould and yeast growth in food and feed production and storage is thus of primary importance and there is great interest in developing efficient and safe strategies for this purpose. In this context, the biocontrol has received much attention in recent years. Lactic acid bacteria (LAB) such as Enterococcus spp., are known to produce different antimicrobial compounds (organic acids, bacteriocins, etc.,) and are important in the biopreservation of food and feed (1,2). LAB are of special interest as biopreservation organisms since they have a long history of use in food and are generally regarded as safe organisms. The majority of the large numbers of reports on antimicrobial activity of LAB have focused on antibacterial effects, while there are only a few reports on antifungal effects (3). On the other hand, one of the effects identified on LAB is the protection against mycotoxins such as aflatoxins (AFs). Dogs are particularly sensitive to the acute hepatotoxic and carcinogenic effects of AFs. Anorexia and depression are the two most visible symptoms of aflatoxicosis in canine species (4; 5; 6; 7). In previous works aflatoxin producers strains and AFB1 were detected from dog foods (8).
