What other things are dried so that they remain unspoilt throughout the year?
Many items are dried to stay unspoiled throughout the year, such as papads, fish, grapes (raisins), spices like chillies and pepper and pulses. Drying removes moisture, which is essential for microbial growth. Without moisture, microbes cannot multiply, so these dried items can be stored for monthsRead more

Bacteria develop resistance when antibiotics are overused or taken incorrectly. If people take antibiotics for viral infections or stop medicine early, some bacteria survive. These surviving bacteria change and become stronger. They multiply and share resistance with other bacteria. Over time, many bacteria no longer respond to common antibiotics. This makes infections harder to cure. Responsible use of antibiotics and hygiene are key to preventing this dangerous problem.
