Management of possible exposure to CJD through medical procedures Salmonella Stanley and Salmonella Newport in imported peanuts Following an international outbreak of Salmonella Stanley associated with consumption of a specific brand of imported peanuts in Australia (1,2) and Canada (3), a request for information was sent via Enternet on 8 October 2001 to ascertain whether any other countries had any cases that may be associated with this product. To date, seven cases have been identified in Australia and Canada; no other countries have reported cases associated with this product. S. Stanley has been isolated from an unopened packet of this product in Australia, whereas in Canada both S. Stanley and S. Newport have been isolated from unopened packets. The peanuts originate from and are produced in China, and are distributed via Singapore. If found in the United Kingdom (UK) these peanuts are more likely to be sold through specialist stores. At the request of the Food Standards Agency (FSA), local sampling was undertaken by the Public Health Laboratory Service (PHLS) and environmental health departments of local authorities in London and the north west to determine whether any of these imported peanuts, on sale, are contaminated with Salmonella spp. To date, three samples of garlic flavoured in-shell peanuts from the same batch with a best before date of 28 June 2003 have been found positive for S. Newport or S. Stanley by the PHLS London Food, Water and Environmental Laboratory and Preston PHL. A further two samples of the same product and batch have been found positive for Salmonella spp. by Chester PHL. Molecular typing of these food isolates together with recent human isolates is in progress in the PHLS Laboratory of Enteric Pathogens (LEP). The UK importer has initiated a recall of the product. As a protective measure, the FSA has advised consumers of what products to avoid, and has issued a food hazard warning asking local authority enforcement officers to ensure that these products are removed from sale (4,5). From 1 January 2001 to 30 September 2001, LEP has reported on 78 and 138 human isolates of S. Stanley and S. Newport, respectively, in England and Wales. References: 1. 2. 3. 4. 5.

Wound botulism in an injecting drug user in Scotland A case of presumptive wound botulism has been diagnosed in a 33 year old male injecting drug user (IDU) in Glasgow, Scotland. The man presented to hospital on 28 September and, shortly after admission, was admitted to the intensive therapy unit with respiratory failure. Clinical features are consistent with infection due to Clostridium botulinum. In the context of last year’s outbreak of severe illness and death among injecting drug users (see below) – mainly from Glasgow, Dublin, and parts of England (1-4) – which arose as a consequence of injecting heroin contaminated with C. novyi and other similar organisms, it seems likely that this latest infection was acquired in the same way. Prior to this outbreak, in February and May 2000, Eurosurveillance Weekly reported on clinical cases of wound botulism in IDUs diagnosed in Switzerland and England, respectively (5-7). Accident and emergency departments, general practitioners, and microbiologists have been informed about the latest case in Glasgow, which, at present, seems to be a sporadic one. Nevertheless, it is important that relevant clinical and public health professionals remain vigilant about recognising and reporting other cases, as it is possible that a batch of contaminated heroin is in circulation.

Severe systemic sepsis in injecting drug users in Scotland in 2000: final report published Last year, Eurosurveillance Weekly covered an outbreak of severe systemic sepsis in injecting drug users (IDUs) in Norway, Scotland, Ireland, and England (1-14). A report into the deaths of 23 drug users who died after injecting contaminated heroin has now been published by a multidisciplinary team in Glasgow (15,16) and is available at <http://www.show.scot.nhs.uk/ggnhsb/>. Doctors investigating the outbreak, which also affected drug users in the north west of England and in the city of Dublin in Ireland, have drawn up 12 recommendations to prevent further deaths. The report describes an unprecedented outbreak of severe illness among 60 IDUs in Scotland, mostly in Glasgow, between April and August 2000. It said that 23 IDUs died as a result of taking the drug, some within hours of presenting to hospitals. All victims developed a serious abscess after they had injected into muscle or accidentally outside a vein. But it is still not known how the heroin was contaminated. Most addicts inject into their veins, and the oxygen in their blood does not facilitate the growth of anaerobic bacteria present in the heroin. In these cases, the acid solution of heroin is believed to have killed the muscle tissue into which it was injected, depriving it of oxygen and providing ideal conditions for anaerobic bacteria to grow. Greater Glasgow Health Board (GGHB) investigated the outbreak, identifying the bacterium Clostridium novyi as the causative agent in many of the cases. GGHB is hoping that this discovery may help earlier recognition of the organism in future cases. In many cases the C. novyi infection caused untreatable multiple organ failure, according to the clinical analysis of the outbreak which affected 109 addicts in Scotland, England, and Ireland. GGBH said it could happen again, underlining the vulnerability of street heroin users and the need for effective treatments. The 12 recommendations made include improving communications between doctors and hospitals dealing with any further outbreak, and also the flow of information to users. The recommendations are as follows. 1. When there is no obvious cause of death in a known drug user, pathologists should be told immediately to enable necessary specimens to be taken. 2. When there is a risk of serious or unusual infection, doctors should inform clinical microbiologists that patients are known drug users and discuss what specimens should be taken. 3. Information about any unusual infection in a drug user should be given to the local public health consultant, who should inform the relevant national centre for communicable disease surveillance. 4. Tissue samples from living and deceased cases involving severe tissue infection should receive additional treatment to facilitate the growth of strict anaerobes. 5. Steps should be taken to ensure hospital laboratories are maintained with qualified staff to enable them to cope with such outbreaks. 6. A properly funded prospective research study should be undertaken to ascertain the underlying incidence and nature of soft tissue infection. 7. Drug action teams should review arrangements for communicating information for those at risk from future outbreaks. 8. Health boards should review arrangements for receiving and treating drug users. 9. Drug action teams should continue efforts to make drug users aware of the dangers of injecting. 10. In future similar outbreaks, there should be proactive, consistent, and open communication with the media. 11. The coordinating health board should use a pre-existing outbreak website to disseminate information, available, and publicised on commonly used search engines. 12. An international meeting should be convened to consider what lessons should be learnt from the outbreak and what could be done to prevent future incidents. A fatal accident inquiry is due to open at Glasgow Sheriff Court next month into the deaths of 18 men and women from Glasgow who died from the apparently contaminated drug batch. An international scientific meeting about the outbreaks of illness among IDUs is being held on 15 and 16 October 2001 at the Royal College of Physicians and Surgeons in Glasgow. Topics will include the identification and investigation of the outbreaks, the epidemiological, microbiological, pathological, and toxicological findings, outbreak management, and public health implications. The meeting is being convened by GGBH, in collaboration with SCIEH, the Public Health Laboratory Service (England and Wales), the Eastern Regional Health Authority (Ireland), and the Centers for Disease Control and Prevention (Atlanta).

Outbreak of serious illness related to contaminated heroin: European network helps improve surveillance of acute serious health events During July 2001, new warnings were issued in Britain about the possibility that a batch of contaminated heroin was back on the market in England and Scotland. The European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) in Lisbon, Portugal, alerted by the Public Health Laboratory Service (PHLS) for England and Wales, passed on these new warnings to the Reitox network of national focal points for immediate dissemination to professionals in contact with drug users throughout the European Union (1). By the end of August, nine potential cases of serious illness (including necrotising fasciitis) had occurred in Scotland, but these were less severe than in 2000. It is suspected that, unlike last year's outbreak, they represent a cluster of mixed infection comprising group A streptococcus and Clostridium perfringens. Additionally, in the last week, the Scottish surveillance network has also reported an isolated case of wound botulism (C. botulinum) in an IDU (see above). At present, there is no evidence that the outbreak of heroin related serious illness in Scotland is related to last year's outbreak, but continued vigilance is needed. In England, there have been two reports of Clostridium novyi isolated from injecting drug users in 2001, one at the beginning of the year and the second recently. The incidents illustrate the value of the European infrastructure for rapidly alerting professionals in the drug field. Furthermore, they show that improved surveillance of acute serious health events among injecting drug users is warranted. Reference: 1. McMenamin J, Goldberg D, Gill N, Wiessing L.

Management of possible exposure to CJD through medical procedures The Department of Health in the United Kingdom is seeking views on this consultation paper produced by the CJD Incidents Panel (1). This expert advisory group was set up in August 2000 by the chief medical officer to advise on issues relating to the possible transmission of Creutzfeldt-Jakob disease (CJD) and variant CJD from person to person through healthcare. Such CJD ‘incidents’ can arise when a patient found to have CJD has previously had surgery, or donated blood, organs, or tissues. There is considerable scientific uncertainty about the transmission risk in such circumstances. In sporadic CJD, abnormal prion protein and experimental infectivity have been demonstrated in brain, spinal cord, and parts of the eye. Rare episodes of transmission have been documented through neurosurgical procedures and in recipients of human pituitary derived gonadotrophins and growth hormone. Person to person transmission of vCJD has not been documented. The distribution of abnormal prion protein in the body in vCJD, however, is wider than in sporadic CJD. This leads to the unquantifiable, but theoretically possible, risk that vCJD may be transmissible through surgical procedures, especially those involving lymphoreticular tissues as well as tissues of the central nervous system, and through donations of blood, organs, and tissues. Normal decontamination and sterilisation procedures do not destroy abnormal prion protein. The proposals put forward by the CJD Incidents Panel to support health authorities and trusts in managing CJD incidents acknowledge the uncertainties and ethical dilemmas posed by the limited scientific knowledge of these risks and their possible consequences. Four main actions are proposed. 1. Provide advice on when instruments or blood products should be removed from use. 2. Establish a confidential database of all possibly exposed people, who would not be routinely informed about their possible exposure. This database, which would be maintained by the Public Health Laboratory Service Communicable Disease Surveillance Centre (CDSC), would be used to increase the knowledge of the risk of transmission. 3. Inform a small group of possibly exposed people where the panel considers there is sufficient risk to warrant public health action (advising people not to donate blood or organs and special precautions should surgery be needed). 4. Publicise the database to enable people to find out if they have been possibly exposed, or to choose to remove their names without learning whether they may have had an exposure. The consultation paper is available electronically at http://www.doh.gov.uk/cjd/consultation. The views of a wide range of healthcare professionals, patient support groups, and other interested people are sought to address a series of questions highlighted within the document. Responses can be returned electronically or by post. Reference: 1. Management of possible exposures to CJD through medical procedures. A consultation paper. CJD Incidents Panel.
