Abstract Salmonella is a major pathogen associated with poultry food products. Over the past 20 years, pressure to reduce human illness from poultryrelated salmonellosis has resulted in intensive research activity as well as stronger regulatory standards in Europe, North America, and, because of international trade policies, throughout the world. In the United States, implementation of a Hazard Analysis Critical Control Point-based inspection program has been credited with reducing the incidence of Salmonella-positive carcasses from approximately 20 to 10. Since 1998, however, the reported incidence of Salmonella in retail poultry from 12 countries implementing similar pathogen reduction programs, including the United States, has averaged 29 positive for Salmonella. Although these reports examined products at retail outlets and used a variety of sampling methodologies, these results appear to contradict the U.S. Department of Agriculture claims for Salmonella reduction. The purpose of this review is to examine this contradiction with a focus on the potential impact of sampling methodology on reported incidences of Salmonella.

Outbreaks of illness associated with consumption of fruit juice have been a growing public health problem since the early 1990s. In response to epidemiologic investigations of outbreaks in which juice was implicated, the U.S. Food and Drug Administration implemented process control measures to regulate the production of fruit juice. The final juice regulation, which became effective in 2002, 2003, and 2004, depending on the size of the business, requires that juice operations comply with a hazard analysis critical control point (HACCP) plan. The Centers for Disease Control and Prevention (CDC) receives reports of food-associated outbreaks of illness. We reviewed fruit juice–associated outbreaks of illness reported to the CDC's Foodborne Outbreak Reporting System. From 1995 through 2005, 21 juice-associated outbreaks were reported to CDC; 10 implicated apple juice or cider, 8 were linked to orange juice, and 3 involved other types of fruit juice. These outbreaks caused 1,366 illnesses, with a median of 21 cases per outbreak (range, 2 to 398 cases). Among the 13 outbreaks of known etiology, 5 were caused by Salmonella, 5by Escherichia coli O157:H7, 2 by Cryptosporidium, and one by Shiga toxin–producing E. coli O111 and Cryptosporidium. Fewer juice-associated outbreaks have been reported since the juice HACCP regulation was implemented. Some juice operations that are exempt from processing requirements or do not comply with the regulation continue to be implicated in outbreaks of illness.

Data regarding Salmonella on raw poultry are very limited in China. The objective of this study was to determine the prevalence of Salmonella on raw poultry at the retail level in six provinces and two national cities in China. Whole chicken carcasses (n = 1,152) were collected from three types of retail markets (large, small, and wet). All samples were analyzed for the presence of Salmonella by using the U.S. Department of Agriculture, Food Safety Inspection Service method. Of 1,152 chicken samples, overall Salmonella prevalence was 52.2%. The highest prevalence was observed in Guangxi Province (65.3%), next in Guangdong Province (64.6%), and then in Beijing (63.9%), Shaanxi Province (50.7%), Henan Province (47.9%), Shanghai (44.4%), and Fujian Province (42.4%), and lowest prevalence was observed in Sichuan Province (38.9%). Salmonella prevalence was significantly different among the six provinces and two national cities. Salmonella prevalence was highest in the wet markets (54.4%) compared with the large markets (50.3%) and the small markets (52.1%), but differences were not significant (P > 0.05). Good manufacturing practices, good agricultural practices, and hazard analysis critical control point systems for Salmonella control in poultry production at the farm, processing, and retail level should be implemented.

ABSTRACT Ready-to-eat (RTE) meat and poultry product samples collected from RTE-producing establishments for the ALLRTE (random) and RTE001 (risk-based) sampling projects of the Food Safety and Inspection Service (FSIS) were tested for both Salmonella and Listeria monocytogenes. The FSIS analyzed Salmonella results for RTE meat and poultry product samples collected for the two sampling projects from 2005 to 2012. Data for 24,385 ALLRTE samples collected from 3,023 establishments and 66,653 RTE001 samples collected from 2,784 establishments were evaluated for the percentages of Salmonella-positive samples, product types of positive samples, and Salmonella serotypes. There also were descriptive summaries with respect to establishment hazard analysis and critical control point (HACCP) size, production volumes, L. monocytogenes control alternatives, geographic location, and season or month of sample collection. Results showed low occurrences of Salmonella-positive samples from the ALLRTE and RTE001 sampling projects, with 14 positive samples (0.06%) for ALLRTE and 33 positive samples (0.05%) for RTE001. Percentages of establishments with at least one Salmonella-positive sample averaged 0.46% for ALLRTE and 1.11% for RTE001. Three product types—sausage products, pork barbecue, and head cheese—accounted for 62% of all positive samples. There were 27 distinct serotypes from 48 Salmonella isolates, with serotypes Infantis and Typhimurium being the most common (5 isolates each). All but one of the Salmonella-positive samples were obtained from establishments with HACCP sizes of small or very small. More than half of the positive samples were obtained from establishments using L. monocytogenes control alternative 3 (sanitation only, highest-risk category). Positive Salmonella samples were found in all geographic regions at all times of the year. Information obtained from these sampling projects is relevant to the prevention of foodborne Salmonella illnesses from RTE meat and poultry products.

ABSTRACT Berries are potential vehicles for the transmission of parasites and have been implicated in illness outbreaks in various countries around the world, particularly in the United States. Although data on contamination of fresh produce with foodborne parasites have been obtained from various global regions, data from Colombia are lacking even though South American countries are major producers of fresh produce, which is both consumed nationally and exported. In this study, we used a previously published multiplex quantitative PCR approach to investigate contamination of strawberries purchased in either supermarkets or local markets in 20 localities. Strawberries were washed in a detergent solution after purchase, and the eluate was concentrated and sent to Norway for molecular analysis. Of the 120 strawberry samples analyzed, wash eluate from 6 samples (5%) tested positive for Toxoplasma gondii DNA, and 1 sample (0.83%) was positive for Cyclospora cayetanensis DNA. These results indicate that strawberries for sale in Bogotá, Colombia, may be contaminated with T. gondii and C. cayetanensis and, therefore, could act as transmission vehicles for these parasites. These data also indicate that cat and human fecal contamination of the strawberries has occurred at some point in their production, transportation, or storage. These findings highlight the need for a hazard analysis critical control point investigation of the strawberry production chain and implementation of measures to reduce the risk of strawberry contamination, thereby minimizing the risk of transmission of parasitic infection via these fruits, which are usually consumed raw.

ABSTRACT In 1996, the Food Safety and Inspection Service (FSIS) published its pathogen reduction and hazard analysis and critical control point (PR-HACCP) rule. The intention of this program was to reduce microbial contamination on meat, poultry, and egg products. The program was implemented in stages between January 1998 and January 2000, with sampling for Escherichia coli O157:H7 and/or Salmonella in large production establishments beginning in 1998. As the PR-HACCP program begins its third decade, it is reasonable to question whether there have been reductions in the frequency of pathogen-contaminated meat and poultry products reaching consumers. This study summarizes the results for over 650,000 samples collected by FSIS between 2000 and 2018 in slaughter and processing establishments across the United States and compares these results to the roughly 100,000 retail samples collected by the U.S. Food and Drug Administration between 2002 and 2017. The data demonstrate that there has been an overall reduction in the occurrence of Salmonella on meat and poultry products, but the direction and magnitude of change has not been consistent over time or across commodities. Although the available data do not support the identification of causal factors for the observed changes, a historical review of the timing of various factors and policy decisions generates potential hypotheses for the observed changes.

The presence of numerous genera of spoilage bacteria, yeasts and molds, and an occasional pathogen on fresh produce has been recognized for many years. Several outbreaks of human gastroenteritis have been linked to the consumption of contaminated fresh vegetables and, to a lesser extent, fruits. Salads containing raw vegetables have been identified as vehicles of traveler's diarrhea, an illness sometimes experienced by visitors to developing countries. Enterotoxigenic Escherichia coli is the most common cause of this illness. Enterohemorrhagic E. coli, specifically serotype O157:H7, has been implicated as the causative agent in an outbreak of gastroenteritis resulting from the consumption of cantaloupes. Outbreaks of salmonellosis in humans have been attributed to consumption of contaminated tomatoes, mustard cress, bean sprouts, cantaloupe, and watermelon. An onion-associated outbreak of Shigella flexneri gastroenteritis has recently been reported in the United States. Outbreaks of human listeriosis have been epidemiologically linked to the consumption of fresh cabbage and lettuce. Gastrointestinal illness caused by the consumption of raw vegetable seed sprouts contaminated by Bacillus cereus has been documented. The ability of Aeromonas hydrophila and Aeromonas sobria to produce several virulence factors has been documented and their fairly common occurrence in water raises concern over public health risks that may be associated with the consumption of salad vegetables, although their role as agents in foodborne illness has not been fully confirmed. Viruses are not likely to grow on contaminated vegetables and fruits but can survive long enough to cause life-threatening illness in humans. An increased per capita consumption of fresh and lightly processed produce in the United States and other countries, coupled with an increase in importation of produce to these countries from regions where standards for growing and handling produce may be compromised, has resulted in heightened interest in outbreaks of human gastroenteritis that may be attributed to contaminated fresh produce, particularly salad vegetables. Likewise methods of handling, processing, packaging, and distribution of fresh produce on a regional or local scale within countries are receiving attention in terms of identifying and controlling microbiological hazards. Hazard analysis critical control point (HACCP) programs are being developed in an effort to minimize the risk of illness associated with consumption of fresh produce. Examples of pathogenic microorganisms associated with fresh produce as well as procedures that can be used to reduce their incidence at the point of consumption are discussed.

Contaminants of man-made and natural origin need to be managed in livestock feeds to protect the health of livestock and that of human consumers of livestock products. This requires access to information on the transfer from feed to food to inform risk profiles and assessments, and to guide management interventions such as regulation or Hazard Analysis Critical Control Point approaches. This paper reviews contaminants of known and potential concern in the production of livestock feeds in Australia and compares existing but differing state and national regulatory standards with international standards. The contaminants considered include man-made organic chemical contaminants (e.g. legacy pesticides), elemental contaminants (e.g. arsenic, cadmium, lead), phytotoxins (e.g. gossypol) and mycotoxins (e.g. aflatoxins). Reference is made to scientific literature and evaluations by regulators to propose maximum levels that can be used for guidance by those involved in managing contamination incidents or developing feed safety programs.

The International Commission on Microbiological Specifications for Foods (ICMSF) has recently proposed a scheme for the management of microbial hazards for foods that involves the concept of food safety objectives (FSOs). FSOs are intended to specify the maximum levels of hazardous agents required to meet a given public health goal. This scheme offers flexibility for the food industry in terms of allowing the use of alternative but equivalent means for achieving a given FSO. This paper illustrates the application of the ICMSF model via the analysis of the microbiological hazard of Staphylococcus aureus in cream-filled baked goods. Cream-filled baked goods have a notorious history as vehicles for foodborne illness, particularly staphylococcal food poisoning. Although the numbers of cases reported in the United States and Europe have declined in recent years, staphylococcal food poisoning may be much more common than is recognized, particularly in other countries. The ICMSF principles for setting FSOs and the use of performance criteria, process criteria, and validation in relation to hazard analysis critical control point and good hygiene practice plans for managing S. aureus in cream-filled baked goods are described.
