SUMMARY
The Juice HACCP regulation published January19, 2001 requires most juice processors to comply with safety standards through implementation of a HACCP program.  This article is designed to help industry understand the events that led up to this regulation and the key points of the HACCP regulation.  It is divided into three sections. The first addresses the outbreak history and microbial, physical and chemical hazards associated with juice. The Juice HACCP rule was enacted because of an increase in the number of foodborne illness outbreaks caused by consumption of fresh juices during the past decade. The second section discusses the development of juice regulations such as the HACCP rule and the requirement of a warning label on all unpasteurized or untreated packaged juice products, advising consumers of the potential risk of consuming these products. The last section deals with new or emerging processing technologies, such as ultraviolet radiation and high-pressure processing, and measures taken to ensure that juice processors abide by the Juice HACCP rule.  One approach to help increase the safety of fresh juice products is to develop a standardized training curriculum for inspectors, which the National Center for Food Safety and Technology (NCFST) has developed. This is readily available at the Center’s web site in pdf format or may be purchased in bound form from NCFST.

SUMMARY
Food safety perceptions and practices of adults have been researched extensively, yet little research exists about high school students’ perceived foodborne illness risks or their food safety concerns.  The goal of this study was to determine Iowa high school students’ perceptions of food safety by measuring awareness of foodborne illness sources; determining perceived risk of foodborne illness from various foods; assessing food safety attitudes associated with home, restaurants, and school; and assessing demographic influences on perceptions.  This research provides a basis for educational material and program development with potentially great impact on future adult consumers. 

Students were familiar with Salmonella (90.7%), E. coli (88.9%), and Hepatitis A (83.7%), but few were aware of Campylobacter (4.8%), Listeria (12.8%), or Clostridium (14.2%).  Students were more concerned about getting sick from eating meat
and eggs than about getting sick from eating fruits and vegetables. Food processors/manufacturers were considered the most likely source of food safety problems (75.8%), followed by restaurants (64.4%), transportation (58.1%), supermarkets (47.1%), home (40.5%), and farms (38.4%). Students were more confident of the safety of food eaten at home than of that eaten at school and were least confident of food from restaurants.

Nearly a third of students (32.5%) had foodservice work experience and 62.3% of students had received some food safety education in school.  Nevertheless, students reported a limited awareness of common foodborne illness sources and perceived risk of foodborne illness.


Microbial Food Safety Considerations for Organic Produce Production:  An Analysis of Canadian Organic Production Standards Compared with US FDA Guidelines for Microbial Food Safety

SUMMARY
Increased attention has been focused on fresh fruits and vegetables, especially raw or minimally processed, as a significant source of foodborne illness. Outbreaks have been linked to both conventionally and organically grown produce. This paper outlines the risks associated with fresh produce, common pathways of contamination, and current trends in organic agriculture. The primary objective was to determine whether the Canadian General Standards Board (CGSB) organic standard is consistent with the production of microbiologically safe produce and to examine the potential for the CGSB organic standard to include considerations for microbial food safety.  This objective was achieved by examining information gaps between the US Food and Drug Administration on-farm food safety guidelines and the organic standard developed by the CGSB.  This examination showed a significant degree of commonality and, in some cases, it was demonstrated that microbial food safety standards are achieved indirectly under organic production. The main difference between the US guidelines and the CGSB standard is the focus on the process rather than the safety of the final product and the lack of discussion of microbial considerations in the CGSB standard. Specific omissions include worker hygiene and recommendations for safe use of processing and irrigation water. The production of safe food is the responsibility of everyone in the farm-to-fork chain. With established relationships between growers and regulatory infrastructure, the CGSB organic standard would be an ideal vehicle for providing organic growers with information and guidelines on identifying and controlling microbial hazards on their produce.

SUMMARY
This study compared manual shaking with mechanical stomaching for preparing ground meats for microbiological analysis. Manual shaking is simple and inexpensive compared to use of a mechanical stomacher.  However, it may not sufficiently homogenize a sample to allow for accurate detection (qualitative methods) or quantitation of particular microbes or microbial groups.  Packages of ground beef (n = 38) and poultry (n = 37) were purchased from a local market.  Using a split-plot experimental design, 25-g samples of each package were prepared by mechanical stomaching and manual shaking for enumeration of Escherichia coli by use of the Petrifilm E. coli/ coliform count plate method. Statistical analysis using the Mixed procedure (SAS, version 8) showed that the two sample preparation methods were not interchangeable (P = 0.0058).  In terms of  E. coli recovery, ground beef and ground poultry were almost significantly different (P = 0.085), but there was no statistically significant interaction between sample preparation method and type of ground meat.  Manual shaking cannot be used instead of mechanical stomaching for ground meat sample preparation.
