HEALTH EFFECTS OF CHEM IC ALS IN FOODS (Contact Mrs. Jean R. Renaud. Technical Secretariat Health Protection Branch. Health and Welfare Canada. Ottawa.) The Health Protection Branch of Health and Welfare Canada cele- brates a Century of Health Protection in 1975. From the I nland Revenue Act of 1875 "to impose license duties on compounders of spirits and to prevent the adulteration of food, drink and drugs". health protection has expanded to the Health Protection Branch of today. consisting of seven directorates: Administration Food Directorate Drugs Directorate Environmental Health Directorate Laboratory Centre for Disease Control Non-Medical Use of Drugs Directorate Field Operational Directorate (Abstracted from Dispatch # 36.

A31 A NEW BIBLIOGRAPHICAL REFERRAL SERVICE The National Science Foundation is developing an information retrieval sxstem. This is now in operation and is called CAN/OLE (Canadian On. LIne EnqUiry). It IS beIng operated by Concordia UnJversIly Libraries and is located in the Science and Engineering Library on the Sir George Williams Campus in Montreal. This system has the capability of retrieving current information in- stantly from large bibliographical data banks. It covers the fields of Bioi. ogy, Chemistry, Computer Science, Engineering, Physics, and Tech_ nology. The data bases include Biographical Abstracts Previews Chemical Abstracts Condensates, Computerized Engineering Index, and Information Service in Physics, Electrotechnology, Computers and Con. trol. The terminal in the library is linked to the computer centre at the N.R.C. via Bell Canada's new communications system. Dataroute. Searches resulting in 25 or more relevant references are usually printed off-line in Ottawa and mailed out within 24 hours. The fee for this service to academic libraries is $15 per request. To all others, except the Concordia University faculty and graduate students, who are allowed to use this service free of charge, the cost is $25 per request. Those requiring additional information should write to: Concordia University The Science & Engineering Library, 1455 Maisonneuve Blvd .. West, Montreal, P.Q. H3G I M8 W.J.E. BOOK REVIEWS MICROORGANISMS IN FOODS, VOLUME 2: Sampling for Micro- biological Analysis; principles and specific applications. International Commission on Microbiological Specifications for Foods. University of Toronto Press, Toronto. 1974.213 pp. $25.00. In the past, the most perplexing problem confronting microbiologists in appraising the microbiological quality of lots of food was the task of obtaining a sample which truly reflected, without bias. the microbial quality of the food. Some of the numerous sampling methods and proce- dures which are being implemented at present are often not derived from sound statistical principles and invariably lead to unsatisfactory decisions being made on the acceptance or rejection of the food. Due to the great liabilities and/or catastrophic consequences which can result from ac- cepting foodstuffs which should actually have been rejected. a more com- prehensive method of sampling is urgently needed. This need has ade- quately been fulfilled by the present volume. The book was prepared after five years of collaboration. study. and consultation among members of the International Commission on Micro- bial Specifications for Foods and recognized authorities in the field of sta- tistics. Although the present text by no means attempts to present solu- tions to all of the problems in this subject. it nevertheless represents the most serious effort and comprehensive text on the market today. The book is divided into two parts. Part I devotes attention to the principles of sampling. This section. comprising of six chapters. dealS with the following topics: Fundamentals of probability and sampling plan. The associated risks involved in the selection of sampling plans. Principles involved in obtaining a representative sample from a lot of foodstuffs. The question of what comprises a lot is discussed. Types of sampling plans available and the suggested choice of sampling plan which should be employed under a given situation. Particular emphasis on sampling plans for detecting the presence of health hazard causing microorganisms is presented. In view of the fact that samples selected provide one with frac- tional information on how the food was processed or handled. the subject of "in-plant" control by emphasising the need to adhere to Good Manufacturing Practices is discussed. Part II of this text includes ten chapters and focuses attention on the subject of appropriate sampling plans. methods of drawing a sample. and the test procedures for the following foods. Fish and fishery products including shellfish. Fresh and processed vegetable products. Dehydrated foods. Milk and dairy products. J. Insl. Can. Sci. Techno!. Alimenl. Vo!. 8. No.2. 1975
