A survey of process hygiene in the Sri Lankan prawn industry. 2. The hygiene status of personnel

Of 262 personnel tested, 137 (52%) were found to be positive for Staphylococcus aureus. Among individual companies the prevalence of S. aureus ranged from 92% (Company No. 1) to 22% (Company No. 2). Although five companies provided a sanitiser hand-dip, this was found to be ineffective for the control of S. aureus. Provision of hand-washing facilities, of protective clothing and of toilet facilities was found to be inadequate for an export food industry.

A survey of process hygiene in the Sri Lankan prawn industry. 3. Critical control points

Of fifteen processing plants surveyed in Sri Lanka, only five were found to have a prawn process which was adequately controlled. Most common process faults were: inadequate chilling of prawns after a wash in 30°C, mains water, the use of large blocks of ice to cool prawns, and high ratios of prawns to ice. There was also ample scope for cross-contamination of the processed prawns.

Observations on the wastage of raw material and recovery of meat in the prawn processing industry

The wastage of prawns due to spoilage in processing factories accounted to about 0-12% in 1974, 0-35% in 1975, 0-3% in 1976 and 0-4% in 1977. Spoilage increases with the time lag between catching and processing and also due to defective icing. The paper discusses the counts of whole prawns required for obtaining meat of specified size grades.

Vibrio parahaemolyticus and the seafood industry

The role of Vibrio parahaemolyticus in food borne gastroenteritis outbreaks associated primarily with the consumption of contaminated seafoods has been well documented. Information pertaining to various aspects of its occurrence in seafoods, procedures for isolation and identification, generation time and inactivation profiles is discussed. Emphasis has been given to the response of V. parahaemolyticus to low temperatures, heating and antibacterial agents. The public health hazard posed by the pathogen is outlined and the guidelines for control are reviewed in detail.

A policy dimension required for technology roadmapping: Learning from the development of emerging wind energy industry in China

Innovation policies play an important role throughout the development process of emerging industries. However, existing policy studies view the process as a black-box, and fail to understand the policy-industry interactions through the process. This paper aims to develop an integrated technology roadmapping tool, in order to facilitate the better understanding of policy heterogeneity at the different stages of new energy industries in China. Through the case study of Chinese wind energy equipment manufacturing industry, this paper elaborates the dynamics between policy and the growth process of the industry. Further, this paper generalizes some Chinese specifics for the policy-industry interactions. As a practical output, this study proposes a policy-technology roadmapping framework that maps policy-market-product- technology interactions in response to the requirement for analyzing and planning the development of new industries in emerging economies (e.g. China). This paper will be of interest to policy makers, strategists, investors, and industrial experts. © 2011 IEEE.

Survey of the properties of the master cartons (corrugated fibreboard boxes) used in frozen shrimp industry

Master cartons for fishery products collected from different prawn freezing factories were evaluated for bursting strength, puncture resistance, waterproofness, combined weight of liners, basis weight of the corrugating medium, weight of the carton, dimensions of the carton, wax content and saponifiable matter and discussed in the light of the ISI standards.

Survey of the properties of waxed duplex cartons used in frozen shrimp industry

Waxed duplex cartons collected from different prawn freezing factories were evaluated for their physico-chemical properties such as bursting strength, puncture resistance, water proofness, tearing, strength, tensile strength, elongation, moisture content, thickness, weight of the carton, dimension, wax content and saponifiable matter. The results are discussed from the point of view of formulation of standards for this most widely employed packaging material for frozen fishery products in the country.

Quality control in the Indian fish processing industry

Quality control is defined as the continuing assessment of a current operation. It is usually the responsibility of an individual or a department directly responsible to the management. In the case of fish and fishery products, quality control includes all the steps taken to protect the quality of the material since catch until it reaches the consumer.
