The problem is that Big Ag has been/and continues to sacrifice food safety for profit. The bill is too weak to solve the problem, however it does reduce risk a little. IMO the bill is weak because politicians are under pressure from food safety groups to tighten regulations and from industry to allow industry to regulate itself. This ...bill is the compromise crafted between those interests, failing to get this bill passed just means the next set of food safety regulations will be even weaker.
That's my take on it.
