Answer:
Purchasing products before their sell by date, selecting fruits that are damage free and washing vegetables before you consume them.
Explanation:
Buying meat in leaking packages
⇒It is never a good idea to buy food from packages that are tampered with, discolored, or damaged. This could mean that the food is unsafe to eat, or there is bacteria inside the package.
Purchasing products before their "sell by" date
⇒This is a good choice. The sell by date tells the consumer when the product should be purchased by.
Selecting fruits that are damage free
⇒This is another good choice. Damaged fruits can have pathogens and bacteria inside of them, so you should always buy damage free fruits.
Purchasing products after their "use buy" date
⇒This is not a good idea. The use buy dates tells consumers when a product should be used buy. If you buy a product after the use buy date, it could be spoiled or expired.
Washing vegetables before you consume them.
⇒This is a great choice. Vegetables and fruits should always be washed. Sometimes they can have pesticides or even bugs on them from when they were growing.
Therefore, the best choices are: Purchasing products before their sell by date, selecting fruits that are damage free and washing vegetables before you consume them.
