Abstract The levels (1–2%) and increasing severity of allergic responses to food in the adult population are well documented, as is the phenomenon of even higher (3–8%) and apparently increasing incidence in children, albeit that susceptibility decreases with age. Problematic foods include peanut, milk, eggs, tree nuts, and sesame, but the list is growing as awareness continues to rise. The amounts of such foods that can cause allergic reactions is difficult to gauge; however, the general consensus is that ingestion of low parts per million is sufficient to cause severe reactions in badly affected individuals. Symptoms can rapidly—within minutes—progress from minor discomfort to severe, even life-threatening anaphylactic shock in those worst affected. Given the combination of high incidence of atopy, potential severity of response, and apparently widespread instances of “hidden” allergens in the food supply, it is not surprising that this issue is increasingly subject to legislative and regulatory scrutiny. In order to assist in the control of allergen levels in foods to acceptable levels, analysts require a combination of test methods, each designed to produce accurate, timely, and cost-effective analytical information. Such information contributes significantly to Hazard Analysis Critical Control Point programs to determine food manufacturers’ risk and improves the accuracy of monitoring and surveillance by food industry, commercial, and enforcement laboratories. Analysis thereby facilitates improvements in compliance with labeling laws with concomitant reductions in risks to atopic consumers. This article describes a combination of analytical approaches to fulfill the various needs of these 3 analytical communities.

Abstract The 4 major driving forces that are expected to lead to increased use of affinity biosensors that meet crucial industrial test specifications, e.g., fast, reliable, cost-effective, and use of low-skilled personnel, are (1) strict legislative framework, e.g., recent changes proposed to the European food safety and hygiene legislation, EC No. 178/2002; (2) industrial shift from quality control to quality assurance procedures, e.g., Hazard Analysis Critical Control Point, ensuring effective positioning in the global competitive trade; (3) just-in-time production resulting in right product every time; and (4) consumer demand for safe and wholesome products. The affinity biosensors field has expanded significantly over the past decade, with a projected global biosensors market growth from $6.1 billion in 2004 to $8.2 billion in 2009, representing major industrial sectors (e.g., Pharma, Medicare, and Food). This brief review is targeted to affinity biosensors developed for the food industry and includes research and development leading to biosensors for microbiological and chemical analytes of industrial concern, commercial biosensors products on the market, and examples of future prospects in this diagnostic field.

HACCP (Hazard Analysis and Critical Control Point) is a concept which identifies, evaluates, and controls hazards, significant for food safety. It is applicable to the entire food chain, "from farm to table". Prevention of a food borne mycotoxin contamination of commodities is the most rational and cost-effective method for preventing adverse effects of fungal metabolites on human and animal health. Deoxynivalenol (DON) belongs to the group of mycotoxins produced by certain Fusarium species, which can damage several vital organs, or demonstrate immunotoxic effect, when ingested in small amounts for a longer period of time. Of particular concern is exposure of children to this mycotoxin through cereals, which are believed to lead to reduced weight gain and decreased liver weights. For that reason, we tried to present HACCP concept for preventing wheat contamination with deoxynivalenol. To be able to apply this system, hazards must be identified and risks assessed, and for that purpose a real picture of area (region) in which preventive measures shall be applied, need to be established. According to the results of the study conducted in the laboratory at our department, DON contaminated wheat samples in the region of Vojvodina accounted for 41,6% in 2004 and 2005, whereas amounts of deoxynivalenol ranged from 57 to 1840 ?g/kg.

This study aimed to verify the hygienic-sanitary working practices and to create and implement a Hazard Analysis Critical Control Point (HACCP) in two lobster processing industries in Pernambuco State, Brazil. The industries studied process frozen whole lobsters, frozen whole cooked lobsters, and frozen lobster tails for exportation. The application of the hygienic-sanitary checklist in the industries analyzed achieved conformity rates over 96% to the aspects evaluated. The use of the Hazard Analysis Critical Control Point (HACCP) plan resulted in the detection of two critical control points (CCPs) including the receiving and classification steps in the processing of frozen lobster and frozen lobster tails, and an additional critical control point (CCP) was detected during the cooking step of processing of the whole frozen cooked lobster. The proper implementation of the Hazard Analysis Critical Control Point (HACCP) plan in the lobster processing industries studied proved to be the safest and most cost-effective method to monitor each critical control point (CCP) hazards.

AbstractThe application of biosecurity in seaweed aquaculture plays an important role in reducing the impact of disease and pest outbreaks. The continuous occurrence of seaweed pests including the macroalgal epiphytes, epi-endophytic filamentous algae and biofilms on Kappaphycus farms may also potentially induce further incidences of the ice-ice syndrome. In this study, on-farm biosecurity management measures were tested on the commercially grown seaweeds Kappaphycus malesianus and Kappaphycus alvarezii during peak ice-ice season at Gallam-Gallam Village, Sabah, Malaysia. The investigation was focused on preventative control measures including the early detection of the ice-ice syndrome and pests through propagule health checks, regular cleaning of the crop thallus and associated long-line ropes and monitoring of the environment. Farm procedures and practices were also assessed in terms of their biosecurity ‘risk’ using the hazard analysis and critical control point (HCCAP) approach. Observations were replicated in two different farm management systems; one system adopted routine biosecurity measures and the other had no biosecurity measures. The results showed that the ice-ice syndrome and pest outbreak was significantly decreased by 60–75% for K. malesianus and 29–71% for K. alvarezii at the farm which adopted the routine biosecurity measures compared with the no biosecurity treatment. The biosecurity measures also significantly improved growth rate and seaweed quality. The infection levels of the epi-endophyte Melanothamnus sp. contributed to the ice-ice syndrome in K. malesianus, whilst the epiphyte coverage was correlated to the ice-ice incidence in K. alvarezii. This study provides the first evidence of biosecurity management measures significantly decreasing the incidence of the ice-ice syndrome and pests on a commercial seaweed farm.

Food safety is an important issue in the incidence of foodborne diseases in society. Kaledo is one of the “must-try” traditional foods of Palu City, Indonesia. The main ingredients used for making this dish are beef and cow’s trotters, which are highly susceptible to microbiological, physical, and chemical contamination. This cross-sectional study aimed to analyze the Good Manufacturing Practice (GMP) and Hazard Analysis Critical Control Point (HACCP) in one of the culinary businesses in Palu City. The GMP assessment was carried out using the self-assessment questionnaire developed by Food Supplements Europe. The results of this study indicated that Kaledo X Food Stall still had not implemented GMP. However, HACCP analysis showed a critical control point (CCP) in the cooking process of Kaledo, i.e., at the time of boiling the meat and bones.

Hazard analysis critical control point (HACCP) module was prepared for one of the most popular fast food momo (chicken momo and buff momo). For this, hazard analysis was conducted in eight different restaurants of Katmandu city by observing all the steps of preparation, monitoring time-temperature throughout the preparation process and collecting samples of different stages of these food. The samples were assessed for total aerobic mesophilic count (TAMC), total coliform count, total Staphylococcus aureus count, total yeast and mold count, detection of Salmonella spp. and Escherichia coli. During preparation of chicken momo, the highest TAMC, yeast and mold count, coliform and S. aureus count were found to be 2.8 × 106cfu/g, 2.1 × 103cfu/g, 1.92 × 105cfu/g and 3.4 × 103cfu/g respectively. While preparation of buff momo, the highest TAMC, yeast and mold count, coliform count and S. aureus count were found to be 2.82 × 106cfu/g, 1.9 × 103cfu/g, 2.1 × 105cfu/g and 2.8 × 103cfu/g respectively. These values and near to these values too were obtained from the samples of pickles, spices, raw momo, mixture of minced meat with spices and raw meat. The organisms originally present in the raw materials were subsequently transmitted to all the preparatory stages but was not observed after steaming and hence the final steamed product of both kinds of momo were free from microorganisms. Thus from the above findings, it was concluded that steaming was the main critical control point (CCP), which if done for proper time and temperature, can eliminate all the contaminating organisms. Key words: coliform count, critical control point, hazard analysis, Staphylococcus aureus, Escherichia coli, Salmonella spp DOI: 10.3126/njst.v9i0.3164 Nepal Journal of Science and Technology 9 (2008) 49-56
