raises the alarm

Is the general idea of the paragraph natural English?

However, a report raises the alarm about the safety of disposable chopsticks which are mostly made from bamboo in factories. For one thing, disposable chopsticks are hazardous to health. Bamboo chopsticks are very likely to go moldy, so that chopstick manufacturers use industrial sulfur dioxide (SO2), which is known to cause damage to the respiratory system, to fumigate and kill mold and hydrogen peroxide to bleach the sticks, so they look white, clean and more attractive. But few people know they are not as clean as they seem.
