The primary tools used to manage grain in bulk storage are Grain Temperature Detection Systems, and Aeration. A temperature detection system is an electronic reading device that is attached to special cables, suspended from the roof of the grain storage. A storage structure may have one, or many cables, depending on the structure diameter. The cables contain temperature sensors at approximately two-meter vertical intervals. Grain temperatures change relatively slowly, and are normally read and recorded once per week. Variations in grain temperature across the grain mass, or localized rising temperatures, can be indications of grain spoilage and the need for managers to take action. But since grain temperature detection is another complete presentation, we will not focus on it today. More importantly, we will focus on Aeration, the process of making changes within a grain mass.
The authors conducted a training workshop on the application of HACC in shrimp farming in Chennai, India on the request of MPEDA and NACA. This article is based on their resource paper.
The Thai shrimp aquaculture industry has had an excellent record in the production of safe products of consistent quality. However, as aquaculture production expands, the industry and regulatory agencies become more concerned with hazards that impact on people!¡¥s health an safety. Specific problems which may be encountered in shrimp aquaculture products include:
