New Zealand – Fronterra Products Did Not Present a Threat

Botulism BlogClost

Dairy products made by the New Zealand company Fonterra that were at the center of a global contamination scare this month did not contain a bacterium that could cause botulism and posed no food safety threat, New Zealand officials said on Wednesday.

The Ministry for Primary Industries said tests showed that whey protein concentrate manufactured by the world’s largest dairy processor contained Clostridium sporogenes, which cannot cause botulism but which at elevated levels can be associated with food spoiling.

Initial tests conducted by Fonterra and a New Zealand government research institute had indicated the presence of Clostridium botulinum, raising fears that infant formula and sports drinks made from the product and widely exported could be dangerous.

The botulism scare caused a recall of products made by multinational brands that may have contained the whey protein in markets like China, Southeast Asia and the Middle East. It also prompted bans in Russia and Sri Lanka.

CFIAEurofins Food Testing UK

Ottawa, September 17, 2013 – The Canadian Food Inspection Agency (CFIA) and Gort’s Gouda Cheese Farm (EST 4478) are warning the public not to consume cheese products described below because they may be contaminated with E. coli O157:H7.

Europe – Surveillance of Six Priority Food- and Waterborne Diseases in the EU/EEA 2006 -2009

ECDC

The European Centre for Disease Prevention and Control (ECDC) is an EU agency [1] with a mandate to operate surveillance networks and to identify, assess, and communicate current and emerging threats to human health from communicable diseases. The agency became operational in 2005. Initially, data were collected for 49 diseases (2008), with three more added in 2012. All data are entered in ECDC’s database system, known as the European Surveillance System (TESSy). Epidemiological overviews of all diseases are provided in the ECDC’s Annual Epidemiological Report. The surveillance of salmonellosis, campylobacteriosis and Shiga toxin/verotoxin-producing Escherichia coli (STEC/VTEC) infection was carried out until 2007 by an EU-funded dedicated surveillance network, Enter-net, which was hosted by the Health Protection Agency in the United Kingdom. In October 2007, the coordination of Enter-net was transferred to ECDC and Enter-net is now under the auspices of the Programme of Food- and Waterborne Diseases and Zoonoses (FWD). After the transfer, the scope was broadened to also cover listeriosis, yersiniosis and shigellosis. For the six priority diseases, surveillance was developed further in close collaboration with nominated disease experts, epidemiologists and microbiologists. This report is the first dedicated epidemiological report on these six diseases, offering a detailed analysis for the years 2006 to 2009. The intended readership includes public health and food safety professionals, policymakers, scientists, and the general public.

Research – Salmonella Antibiotic Resistance

Food Safety NewsSalm

The number of antimicrobial-resistant Salmonella serotypes hasn’t increased drastically in recent years, but drug-resistant Salmonella continues to pose a public health threat in the United States, particularly as resistance spreads across classes of drugs, necessitates the use of more expensive drugs, makes treatment less effective, and, in worse-case scenarios, leaves infections untreatable.

A recent Centers for Disease Control and Prevention study identified increasing resistance to a class of drugs called Cephalosporins, which are commonly used to treat severe Salmonella infections in adults and are the main drug of choice when treating children, for whom the fluoroquinolone class of drugs is not recommended. Currently, about five percent of Salmonella strains are resistant to Cephalosporins, mostly in cases of Salmonella Heidelberg and Salmonella Newport.

Research – Effect of Pickling on Pathogens in Hard Boiled Eggs

Journal of Food BiochemistryEGGS

Traditional methods of food preservation, such as pickling, have reemerged as popular approaches for home and commercial food processing. The process of pickling hard-cooked eggs (HCE) can be an effective method of preventing the growth and survival of pathogenic microorganisms. Because of the variety of pickling processes, HCE manufacturers must validate their pickling process for Food and Drug Administration (FDA) approval and demonstrate 5-log reductions of pathogens associated with the product. In this study, a rapid one-step pickling process was evaluated for its ability to reduce Salmonella spp., Listeria monocytogenes, Staphylococcus aureus and Escherichia coli O157:H7 inoculated onto HCE for 14 days at room temperature. All pathogens inoculated onto HCE were reduced by (>5.0 logs) within 24 h and were undetectable following enrichment. The data obtained in this study may be of interest to regulatory officials and processors of HCE seeking pathogen reduction validation for their products.
