The microbiological quality of the final product and the safety of the production procedures were screened in an ice cream factory, after implementation of a Hazard Analysis Critical Control Points (HACCP) system. We analysed 30 vanilla (IC1), 30 strawberry (IC2), and 30 chocolate flavoured (IC3) samples of ice cream; 30 of water; 90 of personnel’s hands flora; 150 of plastic ice cream containers flora; 50 of sanitised equipment-surfaces flora. After HACCP introduction, Staphylococcus aureus was not further detectable in ice cream and Escherichia coli was mostly less than 10 CFU/g, while the spoilage markers (total coliforms – TC, aerobic plate counts – APC) in ice cream and the environment were reduced by 20–35%. Mean log CFU/g, for IC1: TC from 2.20 reduced to 1.57, APC from 4.58 reduced to 3.62. For IC2: TC from 2.29 reduced to 1.65, APC from 4.61 reduced to 3.49. For IC3: TC from 2.67 reduced to 1.76, APC from 5.08 reduced to 3.81.

The microbiological quality of 30 production lots of charcoal-broiled river lampreys was studied at three lamprey processing plants (plants A, B, and C). Samples were taken directly after charcoal broiling and stored at 22 and 3°C. Lampreys were examined on the day of manufacture, and those kept at 22°C were examined every second day for 6 days. Samples kept at 3°C were examined every fourth day for up to 24 days. On the production day, the mean aerobic plate counts (APCs) for broiled lampreys from plants A, B, and C were 2.29 log CFU/g, 1.88 log CFU/g, and undetectable (1.67 log CFU/g), respectively. At 22°C, the mean APCs for samples from plants A, B, and C increased markedly within 4 days, and after 6 days the counts for samples from these plants were 8.56, 5.04, and 6.23 log CFU/g, respectively. Chilling and storage at 3°C remarkably improved the shelf life of the product. The levels of bacteria in charcoal-broiled river lampreys from plant A were higher than those in lampreys from plants B and C. No significant increases in APCs were observed during storage at 3°C for 24 days; mean APCs did not exceed 2.80 log CFU/g for samples from any plant. Staphylococcus aureus was found in two samples. No lactic acid bacteria, thermotolerant coliforms, enterococci, Clostridium perfringens, or Listeria monocytogenes was detected. Microbiological data from this study will be used for the development of a hazard analysis for the determination of critical control points.

Atp Bioluminescence Assay

The meat industry is in need of faster and more reliable methods to determine microbial loads in food products. A rapid method (<15 min) has been developed to assess the microbiological quality of chicken carcasses using the adenosine triphosphate (ATP) bioluminescence assay. The results indicate that, following modifications, the ATP bioluminescence test produced an acceptable correlation with plate counts (r = 0.85, p < 0.001) and demonstrated good repeatability between replicates. It is envisaged that the modified ATP bioluminescence assay would best be used as a platform rejection test. Using threshold levels determined from the regression equation, the ATP bioluminescence assays gave about 90% agreement with plate counts for carcass rinses with counts above 5 × 104 CFU/ml. These findings suggest that the modified ATP bioluminescence assay could be used for monitoring critical control points (CCPs) in programs based on hazard analysis of critical control points (HACCP).

Pattern minas cheese is a product developed with pasteurized milk, fermented with mesophilic cultures, and with the final addition of rennet. This cheese undergoes an artisanal maturation process and possesses a firm shell of yellowish color and striking and acidic flavor. Our study objective was to evaluate the microbiological quality of pattern minas cheese. We collected 40 samples from two micro regions (Uberlândia and Patos de Minas) of the Triângulo Mineiro and Alto Paranaíba mesor regions of the State of Minas Gerais, Brazil. The microbiological test results were recorded as counts of enterobacteria, Escherichia coli, coliforms at 35°C, coagulase-positive Staphylococcus and Salmonella spp. In the Patos de Minas micro region, the results were 45%, 35%, 20%, and 20% higher than 103 CFU/g for the counts of enterobacteria, Escherichia coli, coliforms at 35°C, and Staphylococcus coagulase-positive, respectively. Five percent of the analyzed samples were positive for Salmonella spp. in the Uberlândia micro region. Based on the findings of the microbiota in the cheese analyzed from the micro regions (Uberlândia and Patos de Minas), we concluded that the hygiene conditions in the manufacturing, handling, transport, and storage stages were precarious, requiring the implementation of Good Manufacturing Practices (GMP) systems, including Hazard Analysis and Critical Control Points (HACCP).

To develop a hazard analysis and critical control point plan for food processing operations, critical control points must be determined. Swine slaughtering and dressing operations were investigated to establish their critical control points. We monitored the microbiology of swine carcasses by surface swabbing carcass bellies at various steps during the process and by quantitating total aerobic plate count (APC) and coliforms. Starting with a dehaired carcass, the sequential steps monitored included presingeing, postsingeing, polishing, and chilling. Initial results indicate that singeing and chilling substantially reduced the levels of APC and coliforms, whereas polishing increased their levels. The hygienic characteristics of individual operations involved in dressing swine carcasses were then evaluated in the second experiment. A set of 40 randomly selected carcasses leaving singeer, polisher, shaver, and washer were sampled. Carcasses were heavily contaminated during the final polishing procedure, and the APC increased threefold compared with prepolishing levels. Washing reduced the bacterial numbers by 69%. To reduce the microbial load on swine carcasses, final polishing and manual shaving steps were not used during the dressing operation on a set of 90 carcasses. APCs on singed carcasses were reduced from 1.34 to −0.15 log10 CFU/cm2 when the final polisher and manual shavers were not used. However, carcasses were subsequently recontaminated with bacteria after evisceration, and the APCs were similar (P > 0.05) regardless of whether the final polishing and manual shaving steps were used, averaging 1.30 and 1.46 log10 CFU/cm2. These results indicated that individual operations can be identified as critical control points, appropriate limits can be set and monitored in a hazard analysis and critical control point system, and steps where further changes to reduce bacterial levels may be needed for swine slaughtering plants.

The article examines the features of the Hazard Analysis and Critical Control Points (HACCP) system as a factor in food safety. The principles of HACCP, formulated in the ISO 22000: 2005 standard, in the Alimentations Commission Codex are compared, as well as in accordance with the Ukrainian regulatory document "Requirements for the development of food safety standards", approved by the Order of the Ministry of Health of Ukraine on October 1, 2012 No. 590. The comparison is carried out in order to establish the compliance of the Ukrainian HACCP system with the international rules, in particular the ISO 22000: 2005 standard. Shown, that the principles of the Ukrainian HACCP system generally comply with international standards, in particular ISO 22000: 2005. This means that the legislation of Ukraine guarantees that, in compliance with it, food products originating from Ukraine comply with international requirements for the control of its manufacture. The guarantee of this is the system of control measures that are provided for by the laws of Ukraine regarding compliance with the requirements of the HACCP system.
