Viruses

Monitoring viruses in food is essential, as pathogens such as norovirus and hepatitis A remain leading causes of foodborne illness worldwide. Contamination commonly arises through direct contact with infected individuals, particularly food handlers, and foods that are manually prepared and not further processed are at heightened risk. Because viral infections can range from mild gastrointestinal symptoms to severe hepatitis, robust detection methods play a crucial role in preventing outbreaks and ensuring consumer safety. Molecular techniques, including highly specific real-time PCR assays, enable precise identification of viral contaminants and form an important part of modern food safety management.

Common Foodborne Viruses

Hepatitis A

Hepatitis A virus can cause serious infections, primarily affecting the liver. Symptoms include gastrointestinal complaints, fever, and skin rash. The virus is mostly transmitted through contaminated drinking water (including ice cubes), contaminated food (mainly mussels, oysters, fruit, and vegetables), or via smear infection.

Novovirus

Noroviruses are responsible for more than 90% of non-bacterial gastroenteritis cases due to their extreme environmental stability. They can cause outbreaks in community facilities such as hospitals, nursing homes, and healthcare facilities. Symptoms include vomiting, diarrhea, and nausea. While norovirus infections can occur year-round, there is an increase during winter months, often referred to as “winter vomiting disease.” The virus can be transmitted directly from person to person or indirectly through contaminated surfaces, objects, food (e.g., mussels, fruits, and vegetables), or water. The minimum infectious dose is between 10 to 100 viral particles.

Solutions such as the SureFast® PATHOGEN real-time PCR kits provide rapid, accurate, and reliable detection across a wide variety of food matrices and environmental samples. Their high specificity supports confident identification of target viruses, while fast turnaround times help producers respond quickly to potential risks. These systems integrate smoothly into existing food safety workflows, offering a versatile and efficient approach to routine monitoring. By adopting advanced molecular tools, food producers can strengthen their contamination control measures and uphold high standards of public health protection.
