Psychrotolerant endospore-forming bacteria Bacillus and Paenibacillus spp. are important spoilage organisms in fluid milk. A recently developed rpoB subtyping method was applied to characterize the diversity and phylogenetic relationships among Bacillus and related sporeformers associated with milk processing systems. Milk samples representing the processing continuum from raw milk to pasteurized products were collected from two fluid milk processing plants, held at 6°C uptothe code date that had been established by each processing plant (i.e., either 18 or 21 days), and plated for bacterial enumeration throughout storage. Bacterial colonies selected to represent the visible diversity in colony morphology on enumeration plates were examined further. Among 385 bacterial isolates characterized, 35% were Bacillus spp., and 65% were Paenibacillus spp. A total of 92 rpoB allelic types were identified among these isolates, indicating considerable diversity among endospore-forming spoilage organisms present in fluid milk systems. Of the 92 allelic types identified, 19 were isolated from samples collected from both processing plants. The same rpoB allelic types were frequently identified in paired raw milk and packaged product samples, indicating that Bacillus and Paenibacillus spp. can enter dairy processing systems through raw milk. Certain subtypes were found exclusively in pasteurized samples, including those that were temporally independent, suggesting the possibility of in-plant sources for these spoilage organisms, including through the persistence of selected subtypes in processing plants. Development of effective control strategies for the diverse array of psychrotolerant endospore-forming organisms that currently limit the shelf lives of high-temperature short-time fluid milk products will require comprehensive, integrated efforts along the entire milk processing continuum.

Experiments were done in 12 fluid milk processing plants to determine their sanitary condition. Tap water was sterilized by membrane filtration and sodium thiosulfate was added to inactivate residual sanitizer. This water was used to rinse the pasteurized milk storage tank, filler bowls and filled containers. Samples of rinse water were filtered through membrane filters which were incubated on media to produce colonies. Total and coliform counts were made. Storage tanks contributed fewer bacteria to the water than other equipment. About 60% of the first cartons taken from fillers were contaminated with at least 1 bacterium per 100 ml of rinse water and 37% contained at least 1 coliform per 100 ml. The method appears useful to evaluate the sanitary conditions of equipment.

The article is focused on the analysis of impact of the final consumer for milk on the price development on the fluid milk processing market. The impact research was based on the dynamic model of intermediate demand function in inverse form. There were examined two approaches for the dynamisation of developed models – the implicit and explicit approach. Implicit dynamic model, which was developed on the base of linear inverse demand function with time lag explanatory variable, wasn’t acceptable in the view of the achieved results of statistical and economical verification. According to this developed model, the quarterly lag in the examined vertical demand linkage did not play statistically significant role. Among explicit dynamic models, the best model with respect to results of T-test of B2 parameter got the following form:pt = +18.8854 – 0.8636 · qt* + 0.1783 · t – 2.7336 · 10–3 · t2; (t = 1, 2, ..., 32).This developed model with the explicit dynamisation fit theoretical economical condition of Law of diminishing demand and its transmission in the researched section of the product vertical – milk. The intensity of the impact of final consumer demand for milk on the price development on the market for fluid milk processing was evaluated on the base of value of B2 and on base of elasticity coefficient FPt(qt*). In view of B2, the rise of the consumer demand for milk by 1 litre implied the decrease in the prices of litre of milk on the market for fluid milk processing approximately by 0.90 CZK. According to FPt(qt*), the increase of the consumer demand for milk by 1 % bring out in average the fall of the prices per litre of milk on the fluid milk processing market by almost 0.60 %.
