2004 viruses

If viruses are present in food preprocessing, residual viral infectivity may be present after some industrial processes. Therefore, it is key that sufficient attention be given to good agriculture practice GAP and good manufacturing practice GMP to avoid introduction of viruses onto the raw material and into the food-manufacturing environment, and to HACCP to assure adequate management of control over viruses present during the manufacturing process.

If viruses are present in foods after processing, they remain infectious in most circumstances and in most foods for several days or weeks, especially if kept cooled at 4 degrees C. For the control of foodborne viral infections, it is necessary to: Heighten awareness about the presence and spread of these viruses by foodhandlers; Optimise and standardise methods for the detection of foodborne viruses; Develop laboratory-based surveillance to detect large, common-source outbreaks at an early stage; and Emphasise consideration of viruses in setting up food safety quality control and management systems GHP, GMP, HACCP.

Abstract Several groups of viruses may infect persons after ingestion and then are shed via stool. United Kingdom 1. Germany 1. In , spammers became more inventive using new obfuscation techniques, rotating domain names and hiding their domain owner information. In the past 12 months, the speed at which they use new techniques has gone from weeks and days to hours and minutes - soon it will be seconds.

This accelerated spam activity now requires constant spam operations with analysis and research at every hour of the day. According to the Anti-Phishing Working Group, in October alone, phishing campaigns hijacked more than 44 brands worldwide.

New spam campaigns included:. Unprotected users are at risk at unknowingly abetting crimes through remote control and use of their computers. Some worms have used armies of zombie computers to launch distributed denial of service attacks against websites such as SCO, Microsoft, Kazaa, 10 Downing Street, the Pakistani government, RIAA, online betting websites, anti-virus and anti-spam companies.

In addition, phishers are recruiting mules in complex money-laundering schemes through legitimate seeming requests. From phishing emails that warn consumers of phishing to money laundering rings, phishing scams have become both more elaborate and more graphically realistic in Most worrisome, however, are a new generation of phishing attacks that wait for users to visit real banking websites before surreptitiously monitoring and secretly recording the login process through Trojan horses.

Well-publicized arrests include Jaschan and the US Department of Justice's "Operation Web Snare" in August, where more than people were either arrested or convicted in connection with online computer crimes.

Unfortunately, this is but a small fraction of the perpetrators in existence, and some criminals, such as Jaschun and 29A virus-writing gang member Marek Strihavka, are being rewarded by security companies who employ them after their arrests. Worryingly, Sophos also reports a continuing need for a formal framework allowing disgruntled computer users to report virus infections or spam easily. Despite legislation, no government has the resources or the infrastructure to effectively and efficiently process public complaints and warnings.

In , organizations will not only need to strengthen their corporate policies to achieve this proactive protection, but also to take advantage of technology to ensure the enforcement of such policies. Continued Mastoras, "In , we're going to see more mass-mailing worms like Netsky and Bagle. Spammers will keep on spamming. All of these criminals will continue to collude and create inventive attacks. Figure 1 Return to top. Figure 2 Return to top. Figure 3 Return to top.
