Silage contains a number of potential hazards to the safety and quality of milk and dairy products. This paper reviews the present knowledge about silage as a source of (1) spores of anaerobic spore-formers (Clostridium species) and aerobic spore-formers (mainly Bacillus and Paenibacillus species), (2) the zoonotic pathogenic bacteria Listeria monocytogenes and Escherichia coli, and (3) mycotoxins. A distinction is made between field-derived mycotoxins, i.e. mycotoxins that are formed during growth of crops in the field, and ensilage-derived mycotoxins, i.e. mycotoxins that are formed after ensiling. The routes of transmission of these hazards from feed to milk, the effect of pasteurization of milk, and reduction strategies are discussed. Aerobic deterioration of silages is a major factor influencing levels of spores of both aerobic and anaerobic spore-formers, L. monocytogenes, and certain mycotoxins.

Bacillus sporothermodurans and other highly heat-resistant spore formers in milk

et al. 2006

A recent example of a micro‐organism causing undesired growth in consumer milk is Bacillus sporothermodurans producing highly heat‐resistant spores (HRS) which may survive ultra‐high temperature (UHT) treatment or industrial sterilization. Molecular typing showed a heterogeneous group of farm isolates (non‐HRS strains), but a clonal group of UHT isolates from diverse European countries and other continents (HRS‐clone) suggesting a common source. During a survey of Belgian dairy farms for the presence of potentially highly heat‐resistant spore formers, high numbers of these spores were detected in filter cloth, green crop and fodder samples. The strain collection showed a high taxonomic diversity with 18 potentially new species and with Bacillus licheniformis and Geobacillus pallidus as predominating species overall. Seventeen B. sporothermodurans isolates were identified, mainly originating from feed concentrate. Heat resistance studies showed the UHT resistance of B. sporothermodurans spores present in industrially contaminated UHT milk, but a lower heat resistance of laboratory‐grown strains (HRS and non‐HRS). Hydrogen peroxide, used as sanitizer in the dairy industry, was found to induce higher heat resistance of laboratory‐grown B. sporothermodurans strains to a certain level. This indicates that sublethal stress conditions may affect the heat resistance. By transmission electron microscopy, structural differences at the spore level were found between HRS and non‐HRS strains. The data indicate that the attainment of extreme heat resistance is rather multifactorial.

A Gram-positive, rod-shaped, motile and spore-forming bacterium, designated ZLD-8(T), was isolated from a desert soil sample collected from Xinjiang Province in north-west China, and subjected to a polyphasic taxonomic analysis. This isolate grew optimally at 30°C and pH 7.0. It grew with 0-4% NaCl (optimum, 0-1%). Comparative 16S rRNA gene sequence analysis showed that strain ZLD-8(T) was closely related to members of the genus Bacillus, exhibiting the highest 16S rRNA gene sequence similarity to Bacillus kribbensis DSM 17871(T) (98.0%). The levels of 16S rRNA gene sequence similarity with respect to other Bacillus species with validly published names were less than 96.3%. The DNA G + C content of strain ZLD-8(T) was 40.1 mol%. The strain contained MK-7 as the predominant menaquinone. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The major fatty acids (>5% of total fatty acids) were anteiso-C15:0 (39.56%), iso-C14:0 (25.69%), C16:1 ω7c alcohol (10.13%) and iso-C15:0 (5.27%). These chemotaxonomic results supported the affiliation of strain ZLD-8(T) to the genus Bacillus. However, low DNA-DNA relatedness values and distinguishing phenotypic characteristics allowed genotypic and phenotypic differentiation of strain ZLD-8(T) from recognized Bacillus species. On the basis of the polyphasic evidence presented, strain ZLD-8(T) is considered to represent a novel species of the genus Bacillus, for which the name Bacillus deserti sp. nov. is proposed. The type strain is ZLD-8(T) (=CCTCC AB 207173(T) = KCTC 13246(T)).
