Sponges and kitchen towels must be replaced regularly. Don’t wash dishes and cutting boards with dirty sponges and towels.
Bacteria and other disease-causing pathogens grow on sponges and towels over time, so clean your sponge thoroughly every other day and replace it about once per week.
Bacteria can grow in enormous numbers on meat, so even a small amount of uncooked or spoiled meat can spread bacteria such as salmonella and E. coli. When it comes to meat and poultry, if you are NOT sure it is safe, do NOT eat it.
